Cloud Based CAD

Cloud Service Based CAD

What is Cloud Based CAD? In a simplistic sense, it means that instead of having CAD software resident locally on CAD workstations or on local network servers, cloud-based solutions enable CAD software to be loaded and run remotely, and to be accessible on the internet to an approved CAD professional.

Before answering the question “How Quickly is Cloud Based CAD being adopted?”, it is useful to know whether there are incentives for CAD organizations to be interested in cloud-based CAD.

  • Is cloud-based computing a novelty, or does it provide benefits such as cost savings, improved productivity, and protection of intellectual property?
  • Are there disadvantages or drawbacks which should be considered before using cloud-based CAD, instead of locally based CAD?

Cloud Based CAD

Answers to these two questions will make it easier to interpret and understand existing data regarding adoption rates for cloud-based CAD. Specifically:

  • Is cloud-based CAD growing, shrinking, or at a standstill?
  • If cloud-based CAD is growing, will it continue to grow? If it is not growing, why is that the case?
  • If cloud-based CAD will grow, at what projected rate?

What Benefits and Drawbacks Does Cloud-based CAD Provide?

Some of the benefits of using cloud-based CAD are:

  • Reduced capital expenditure, because it reduces the need to purchase and maintain workstations
  • Reduced cost of licensing CAD software on individual workstations
  • Global access to CAD software, and elimination of the need to co-locate CAD personnel
  • Increased productivity and collaboration
  • Provision for data backup and recovery, and certain levels of security
  • Reduced energy usage and reduced carbon emissions

Some of the drawbacks are:

  • The risk of security breaches and the danger of losing sensitive business data to hackers
  • Availability issues due to downtime or system outages
  • Inadequate internet bandwidth for certain mission-critical projects
  • Loss of control over company data, and the risk of entrusting protection of company data to an external organization
  • The potential for hacker intrusion and theft of sensitive, classified data

Is There Resistance To Adopting Cloud-based CAD?

The benefits of cloud based CAD seem compelling from a business viewpoint, even if there are some drawbacks. However, it appears from published reports that the current adoption rate of cloud-based CAD is probably between 20% and 30%. Although many businesses are seriously considering the adoption of cloud-based computing, either they have done so in a limited way, or they have not taken the plunge.

Since cloud-based computing provides many benefits, what reasons or concerns are delaying or resisting adoption of the service?

The three top concerns are:

  • Security (61%)
  • System Integration challenges (46%),
  • Information governance (35%).

This probably means that although many CAD organizations are carefully evaluating cloud-based offerings from many vendors, the organizations are in no hurry to adopt cloud-based CAD. This makes sense, because the potential for security breaches, the potential for hackers to steal sensitive company design data, and system performance issues are too risky to be taken lightly.

Until the drawbacks of cloud-based computing are resolved or eliminated, it makes sense for CAD organizations to:

  • Maintain software applications which handle sensitive company data on their own firewalled local servers,
  • Use cloud-based computing for handling data which does not require security clearance,
  • Use a combination of privately-maintained cloud computing together with locally-based computing (hybrid cloud computing).

It is necessary to define three main categories of cloud computing:

  1. Public cloud computing provides both computing resources and data management to the general public. The service is provided either freely or on a pay-per-usage model. This type of service is useful when security is not a major issue.
  2. Private cloud computing appeals to large enterprise organizations which have sensitive data, and require high levels of data protection and security clearance.
  3. Hybrid cloud computing uses the best of both public and private cloud computing. This is a good choice for CAD organizations which want to “test the water” before diving into fully-fledged cloud computing.

What Does Existing Data Say About Adoption Rates Of Cloud-based CAD?

The adoption rate for cloud-based computing depends on the type of software application. Although many types of cloud-based services are available, there are three main types:

  • SaaS (Software as a Service) or “on-demand” software migrates easily to the cloud, because security issues are minimal. Clients usually access SaaS with web browsers. The adoption rate is about 49%.

    Examples of SaaS are Google Apps, Microsoft Office 365, Twitter, Flickr, Dropbox, and Facebook.
  • PaaS (Platform as a Service) provides a computing platform on which software applications can be developed and deployed. Because PaaS provides a virtualized computing environment, software developers can focus on writing software without being concerned with attendant OS-driven tasks. The adoption rate is about 18%.

    Examples of PaaS are AWS (Amazon Web Services) Beanstalk, Google App Engine, Heroku, and Red Hat’s OpenShift.
  • IaaS (Infrastructure as a Service) provides scalable computing resources in a virtualized environment, and it manages cloud-enabled data.  Because IaaS clients have control over SaaS and PaaS clients, IaaS is the most likely candidate to be adopted by CAD organizations.

    IaaS could be used to develop applications for SaaS and PaaS environments. The adoption rate is about 28%.

    Examples of IaaS are Windows Azure, Rackspace, CloudSigma, HPCloud and Softlayer.

Is It Likely That The Adoption Rate Of Cloud-based CAD Will Grow?

A report by Cisco reveals that by 2018,

  • 31% of cloud workloads will use public cloud service,
  • 69% of cloud workloads will use private cloud service.

Furthermore,

  • 59% of cloud workloads will use SaaS, an increase of 41% from 2013,
  • 28% of cloud workloads will use IaaS, a decrease of 44% from 2013,
  • 13% of cloud workloads will use PaaS, a decrease of 15% from 2013.

If these projections hold true, the adoption rate of cloud-based CAD should either remain the same or decrease. Any more growth in the adoption of cloud-based CAD will probably occur as IaaS, within the realm of either private or hybrid cloud computing.

Is there a cloud for AutoCAD?

Yes, AutoCAD has options for cloud-based storage and collaboration. Autodesk, the company behind AutoCAD, offers a service called “AutoCAD Web and Mobile” which allows you to access your AutoCAD files online through a web browser or a mobile app. This service also integrates with cloud storage providers such as Autodesk’s own cloud storage solution, Autodesk Drive, as well as other popular platforms like Google Drive, Dropbox, and OneDrive. With these cloud integrations, you can store your AutoCAD files in the cloud and access them from anywhere with an internet connection.

Is there a online CAD program?

Yes, there are several online CAD (Computer-Aided Design) programs available. Some of the notable ones include:
AutoCAD Web App: This is the online version of the popular AutoCAD software by Autodesk. It allows you to create, view, edit, and share CAD drawings directly in your web browser.

CAD plays a vital role in understanding the plan for the electrical fittings and creating CAD drawings. Before CAD machines were found, the construction field needed architects that could elaborate with detailed drawings on a sheet of paper. There were many problems with the process. Not only is it fallacies drawing, but it pins down all the details by taking care of the different views and angles that come with particularly complex.

However, using electrical CAD drafting services makes it easier to handle the construction process. By following a few ways in which electrical CAD drafting turns out handy in construction.

ACCURATE DRAWINGS WHICH CAN BE SCALED

It helps electrical CAD drafting to make the most detailed drawings. CAD software is often packed with a bundle of features. Not only you can change the scale, but you can make smart use of annotations and a few parameters with ensuring that you are making detailed and precise drawings.

With the help of electrical CAD drafting, you can handle the different details without the margin of error. When using CAD software, you will rely on the program for making all the drawings. It reduces the margin error significantly.

ADAPT TO VARIOUS CHANGES

In the construction field, making changes can be tough to visualise. Even when altering a very minute part of the design, you need to visualise how it will impact the rest of the structure. We may often end up missing crucial factors, which will lead to problems in the long run. However, with the support of electrical CAD drafting, you can make edits and modifications.

If there’s a need for some change in design, the user can implement it on a CAD drawing. They can analyse how the changes will impact the rest of the design. If there are huge ramifications, one can take another alternative. One needs to make minor changes in CAD software and thereby remodel with finesses.

Hence, when it comes to modifications, the constructions are underway. As it’s electrical CAD drafting that turns out to be handy in several ways.

HAVE A BLUEPRINT

It helps electrical CAD drafting with having a blueprint before one puts the plans into action. There are times when it has been seen that architects find it hard to visualise every single thing. However, the Cad software is well designed and finds a three-dimensional look. It helps to get a great deal with making a design feasible and looking good.

Electrical CAD Drafting In Construction Field

Since CAD started using architects, it adds importance that cannot be replaced. This makes it looks like part of the core construction process. The software offered a wide variety of use and made the construction process easier. It’s a lot more reliable and less prone to errors.

What is a CAD designer in electrical?

A CAD designer in electrical engineering is a professional who specializes in creating detailed technical drawings, plans, and diagrams using computer-aided design (CAD) software specifically tailored for electrical systems. CAD designers in electrical engineering play a crucial role in the design, development, and implementation of electrical systems in various applications such as buildings, industrial facilities, power plants, infrastructure projects, and more.

The primary responsibilities of a CAD designer in electrical engineering include:

Raster Image Formats

It adds many 3D CAD file formats for storing and transmitting data. CAD file formats are classified in terms of two distinct forms. It offers bitmap or raster format and the vector format. The distinction clarifies the two formats by pointing out the critical difference between them.

The raster format adds images in terms of pixels. On a display monitor, the pixels work as dots that carry colour attributes and levels of intensity in RGB. Raster graphics are suitable for photographic images adding resolution-dependent. One does not need to scale higher resolutions without loss of quality. It uses an image that is grainier by adding image details. The vector format represents images as lines, points, curves and polygons on an algebraic grid. The primitives are utilised to create vector-based images. It scales up to any resolution without loss in quality.

Raster Image Formats in CAD

The essential difference between raster and vector-based images covers raster images when scaled higher than the resolution we create. On the other hand, vector images are scaled up or down without any loss in image quality:

  • Popular raster-based formats include JPEG, PNG, BMP, and TIFF.
  • Popular vector-based formats add EPS, PDFor AI, SVG (Scalable Vector Graphics), WMF (Windows Metafile Format), DXF (Drawing Exchange Format), DRW, and DWG formats.
  • Compound formats come with EPS, PDF, SWF, and PICT and contain pixel and vector-based data.

Raster Image Formats in CAD

It determines whether the raster image format disappears from CAD file systems. This article answers all specific questions:

  • How popular is vector format based on leading CAD vendors?
  • Which CAD file formats come with 3D printing technology?
  • Is any particular CAD file format suited for CAD data exchange?
  • Why raster format remains an essential part of CAD file systems?

HOW POPULAR IS VECTOR FORMAT AMONG LEADING CAD VENDORS?

It offers modern CAD software packages storing design and drawing information in vector format. To confirm this observation, it’s worthwhile to look at CAD formats that lead to CAD vendors, such like:

  • AutoDesk is used as its native file format, supporting DWG, DXF and more.
  • AutoCADuses the DWG and DXF vector formats.

SolidWorks mainly uses a structured format in which different file formats are embedded. The design data are stored in the DXF vector-based formats covering AI, GCR, and STL. It keeps in a structured layout. The structured format also holds raster formatted images.

Many software applications can convert images between the raster and vector formats. It adds significant images that convert CorelDRAW, Easy Trace, WiseImage, Freehand, VP Software, and others. It leads to CAD vendors that convert between raster and vector file formats. 

WHICH CAD FILE FORMATS ARE MOST FAMOUS FOR 3D PRINTING TECHNOLOGY?

The format used for 3D printing comes with STL (STereoLithography) format. We aren’t sure whether any CAD file format is most suitable for 3D printing. It leads to 3D companies, including Stratasys and 3D Systems, that convert automatically into recognisable CAD files. Further, CAD vendors export their files into STL, including Catia, Autodesk Inventor, SolidWorks, SolidEdge and ProEngineer.

IS THERE ANY PARTICULAR CAD FILE FORMAT BEST SUITED FOR CAD DATA EXCHANGE?

There is no answer to this question. The CAD file exchange software will have the ability to convert between raster and vector formats. The reason requirement comes with a modern CAD file system. It moves towards a structured file format that works better in which both raster and vector file formats are embedded. The contemporary CAD files contain more drawings and design information. It makes sense to come with different file formats stored within a structure adding minimal information lost during file transmissions.

An excellent example is integrating different data types into a CAD file offered by BIM (Building Information Modelling). BIM helps incorporate activities for parties and disciplines involved in a building project. It comes with a synergistic body that exchanges different information types. With other teams working together on a project, it needs to use different file formats that add information exchange.

Also, the Raster formats need visual displays, virtualisation and animation. It’s vector formats that use design drawings which is scalable. BIM offers a valuable extension on the CAD file format that’s not recognised as a CAD file format. The complexities integrate CAD file formats adding necessary coin a different acronym for a unified file format that does not primarily contain CAD information.

The answer to the question “Is any CAD file format best suited for CAD data exchange?” is no, with qualifications. If the CAD data is exchanged strictly in design drawings, the vector format is best suited for the data exchange. It comes with scalability and without loss of data information. The CAD data is exchanged strictly in pictorial views or animation. Then the raster format, created with a high enough resolution, works best suited for the data exchange. 

WHY WOULD THE RASTER FORMAT REMAIN AN ESSENTIAL PART OF CAD FILE SYSTEMS?

Although raster images not scale up without losing data, they are indispensable for conveying pictorial information and producing animations. The current trend helps store CAD data that leans toward structured file format in which different file formats embed. As each primary CAD format has its right, the raster format undoubtedly remains an essential part of CAD file systems.

What is a raster image in CAD?

Raster and vector are two different approaches used in computer-aided design (CAD), each with its own advantages and applications:
Raster CAD:
Raster CAD works with images composed of a grid of pixels, similar to photographs or scanned images.
It is primarily used for creating and editing images that are based on pixels, such as photographs or digital paintings.
Raster CAD software typically includes tools for editing individual pixels, applying filters, and working with layers.
Common file formats for raster CAD include JPEG, PNG, TIFF, and BMP.
Vector CAD:
Vector CAD works with mathematical equations to define shapes and lines, rather than pixels.
It is used for creating precise drawings and designs that can be scaled to any size without losing quality.
Vector CAD software allows users to create and edit shapes using points, lines, curves, and other geometric primitives.
Common file formats for vector CAD include SVG, DXF, DWG, and AI.

What is a raster image?

A raster image, also known as a bitmap image, is a type of digital image composed of a grid of individual pixels (picture elements). Each pixel contains specific color information, and when arranged together in a grid, they form the visual representation of an image. Raster images are commonly used for photographs, digital artwork, and any other type of image that requires complex color and shading variations.
Key characteristics of raster images include:
Pixel-Based: Raster images are composed of pixels, each with its own color value. The resolution of a raster image determines the number of pixels it contains, which in turn affects the image quality and detail.
Resolution Dependent: Raster images have a fixed resolution, meaning they have a specific number of pixels per inch (PPI) or dots per inch (DPI). Changing the size of a raster image can result in a loss of quality if the resolution is insufficient.
File Formats: Common file formats for raster images include JPEG, PNG, TIFF, GIF, and BMP. Each format has its own compression methods and features, suitable for different types of images and purposes.
Editing: Raster images are edited using image editing software like Adobe Photoshop, GIMP, or Paint.NET. Editing operations include adjusting colors, adding filters, cropping, and retouching.
Scalability: Raster images are not inherently scalable without loss of quality. Enlarging a raster image beyond its original resolution can result in a loss of sharpness and detail, known as pixelation.

Mobile CAD Computing

When the PC (Personal Computer) was introduced in the late 1970s to early 1980s, the computing world witnessed progressive miniaturization of the PC into smartphones, laptops, and tablets that recently added to computerized watches. It comes with the availability of the internet along with cloud computing, which helps reduce computing power on individual computing devices.

Mobile CAD Computing

Additionally, packing computing power in a computing device access the computing power provided by servers, including distributed computing environment. Let’s say a consumer desktop or laptop isn’t suitable to run 3D CAD software. As CAD operations add complex computational procedures, it needs high performance using dedicated processors. Therefore, CAD workstations provide high-performance computational power adding snappy information that exchanges the networks in a cloud-based computing environment. A CAD engineer carries their workstation to meetings, design reviews, and business trips. All it requires is the mobility Mobile CAD Computing device, including:

  • Get performance compares to that of a CAD workstation

  • How does a mobile cad workstation perform as well as a traditional workstation?

The CAD analysts use the total CAD workstation market that comprises mobile and desktop workstations that continues to grow. Mobile CAD workstations come with the overall market. It adds mobile workstation sales that remain steady with 25% of the total workstation market.

A survey conducted by an industry research firm found that it grows mobile CAD workstations. This interest comes with declining desk-side PCs, consumers-class notebooks and workstations. Also, it finds several mobile CAD workstations that are used primarily for creating and editing CAD drawings. It uses accessing data and CAD drawings. Nevertheless, demands for mobile CAD workstations are expected to show strong growth in the next few years.

Before PCs became popular in the 1980s, most CAD workstations were RISC-based systems such as DEC Alpha, MIPS, PowerPC, and SPARC. Afterwards, CAD workstations used operating systems such as Microsoft Windows, GNU/Linux distributions, Apple Mac OS X, and Oracle Solaris. 

The features of a top-end high-performance CAD workstation include the following:

  • High-performance processors from 4 to 18 cores, with base clock, speed up to 3.5 MHz, 2.5 MB core of last level cache, and DDR4 registered DIMM support for up to 32 GB of RAM.
  • Graphics GPU with up to 12 GB of memory as in the NVidiaQuadro K6000 graphics card. A high-performance GPU is necessary for 3D animations and rendering. Investing in a high-performance processor for everyday CAD design work is more productive.
  • Up to 24-inch LED display with a minimum high-level resolution of 1280 x 720. Typically, a top-performance workstation supports multiple displays.
  • SSDs (Solid State Drives) instead of hard drives, or a combination of SSDs and hard drives.
  • It points virtualisedCAD workstations that add a more productive CAD development environment. It relies on cloud computing, adding hardware virtualization. Virtualized workstations add cost-effectiveness in terms of hardware maintenance and upgrade cycles. It comes with a mobile CAD workstation which cannot compete with a top-end CAD workstation in terms of performance. It uses good economic sense by using a mobile workstation in that cloud-based distributed computing environment. It comes in an atmosphere of virtualized workstations.

WHAT ARE THE MAIN ADVANTAGES AND DISADVANTAGES OF USING MOBILE CAD WORKSTATIONS?

A mobile CAD workstation cannot match the performance of a top-end high-performance desktop CAD workstation. However, interest is growing in mobile CAD workstations, while interest is declining for desk-side PCs, workstations, and consumer-class notebooks. Mobile CAD workstations offer an advantage over unmatched traditional CAD workstations. It’s worthwhile to list a few benefits. Along with a mobile workstation, it offers complimentary performance with a desktop CAD workstation that provides mobility.

Getting a mobile CAD workstation used for project managers and executives comes with a primary interest in viewing, accessing, data and reviewing CAD drawings rather than creating them. The mobile CAD workstation is mainly used in field operations, adding CAD engineers that require to access and view data and CAD drawings.

What is CAD in computing?

In computing, CAD stands for Computer-Aided Design. CAD refers to the use of computer software and systems to assist in the creation, modification, analysis, or optimization of designs, typically in engineering, architecture, and manufacturing industries.

Virtual Prototyping Reality?

Lot of manufacturing organizations support reducing TTM (Time to Market). It helps to optimize product designs to maximize reality and get optimum performance. A typical product design cycle refers to PLM (Product Lifecycle Management), which comes with phases that include:

  • Tooling Design
  • Conceptual Design
  • Detailed Design and Validation
  • Product Build and Assembly
  • Manufacturing planning and implementation
  • Reliability Testing

It adds essential phases covering the preliminary phases of PLM, which are costly and time-consuming. In a typical PLM, physical prototypes and end products are tested and produced for reality, performance and functionality. It usually takes a lot of design and manufacturing iterations to make acceptable test results before launching the product. Many reasons cover the preliminary phases of PLM that are costly and time-consuming. Virtual Prototyping emerged as a promising method to create virtual rather than physical prototypes. It tests with simulation software that develops into a mature technology that offers tremendous benefits to manufacturing organizations.

  • To understand Virtual Prototyping, answer a few questions given below:
  • How CAD technology included in Virtual Prototyping?
  • To what extent does Virtual Prototyping use?
  • What benefits does Virtual Prototyping offer? 

HOW IS CAD TECHNOLOGY INVOLVED IN VIRTUAL PROTOTYPING?

The goal of Virtual Prototyping to use engineering simulation software that predicts the performance and reliability of product assemblies manufactured. Virtual Prototyping referred to as Systems Performance Modelling. It predicts the reality and performance that simulates software, adding complex and challenging tasks. To understand how components of a product deform individually under loadings, it deformed the assembly into a product.

It understands how the material properties of parts degrade with product life. The material properties degrade with low to high-temperature changes. It comes with chemical reactions in a corrosive environment. It supports an understanding of the nature of loadings. Let’s say cyclical loadings occur to wind forces, ocean wave forces and earthquakes. A product is subjected to vibrational forces created by neighbouring machinery.

It helps in understanding the manufacturing defects initiated with growth and propagation. It adds failure modes of parts that influence the performance of the entire assembly regarding reliability. Apart from these, it adds factors to be considered, including governmental regulations, manufacturing techniques and environmental issues for building a product. The main CAD-related tools mainly utilised Virtual Prototyping, which covers 3D CAD design and simulation tools, along with CAE analysis. These tools use designing parts that are well-known for static or dynamic loadings. It can perform crash simulations, including finite element analyses.

However, simulating the performance and reliability of an assembled product requires more sophisticated software that integrates the capabilities of these CAD tools. The main goal is Systems Performance Modelling and Virtual Prototyping.

Implementing successful simulation software predicts the reliability and performance of a product, making it possible to examine different design alternatives. It commits to specific product intent. If there’s Virtual Prototyping achievable, it benefits manufacturing organisations with ease. It points to the availability of Additive Manufacturing or 3D printing. It utilised to validate simulation software developed for Virtual Prototyping and more.

TO WHAT EXTENT IS VIRTUAL PROTOTYPING USED?

As Virtual Prototyping sounds, it’s used by specific organisations that make good progress in implementing the technology. It’s worthwhile to look at what’s been accomplished.

Mazda® use a Virtual Prototyping solution named CoMET from Synopsys®. It helps reduce the number of tests on actual automobiles to verify ECUs (Engine Control Units) and HIL (Hardware-in-the-loop) test equipment.

HIL offers simulation techniques that quickly test and develop embedded systems for automotive computer systems. Mazda credits the Virtual Prototyping tool that accelerates ECU development at lowering cost. Another company that benefits from Virtual Prototyping is Ford®.

If we talk about Optitex®, it’s an apparel manufacturer that uses a robust set of virtual fabric simulation software to create, view and edit accurate apparel patterns before putting them on the market. The virtual software offers the company a shorter time to market. It adds improved innovation and customer satisfaction. Let’s say the design parameters include fitting, pulls, buttons, zippers, pleats, buckles, seam finishes, repeats, and more parameters that manipulate a virtual environment. Another apparel manufacturer adds benefitting from virtual Prototyping is Tukatech®.

WHAT BENEFITS DOES VIRTUAL PROTOTYPING PROVIDE?

Although many benefits that Virtual Prototyping provides have been mentioned, it will be used to summarise the most important benefits. Virtual Prototyping performs repeatable tests on a virtualised product under conditions that are difficult to create. Virtual Prototyping performs design modifications on a virtualised product, testing the product and optimised design, which is cost-effective, robust, and reliable.

Virtual Prototyping makes it possible to test and virtualise products against failure modes adding effects, different loadings types, and other operating conditions like low or high temperatures. It’s used for customers who misuse products, adding corrosive environments.

Virtual Prototyping Reality?

Virtual Prototyping shortens the product design time by making it easy to introduce new products with less time to market. It offers better customer satisfaction by increasing product presence in the market. CAD/CAM software systems are integral to Virtual Prototyping or Systems Modelling software. It adds availability to 3D printing, using certain types of Virtual Prototyping simulation software that validate and develop with 3D-printed models.

What is virtual reality prototyping?

Virtual reality (VR) prototyping involves using virtual reality technology to create and test prototypes of products, environments, or experiences. Instead of building physical prototypes, which can be time-consuming and expensive, VR allows designers and developers to create digital simulations that users can interact with in a virtual environment.

In VR prototyping, designers can create 3D models of their designs and place them within a virtual space. Users can then put on a VR headset and interact with these virtual prototypes as if they were real. This allows designers to test different design ideas, gather feedback from users, and iterate on their designs much more quickly and efficiently than traditional prototyping methods.

VR prototyping is particularly useful for industries such as architecture, automotive design, product design, and video game development, where being able to visualize and interact with a design in 3D can greatly enhance the design process. It can also be used for creating virtual prototypes of user interfaces, allowing designers to test the usability of their designs in a more immersive way.

What are the techniques used in virtual prototyping?

Virtual prototyping is a method used in product development to create and evaluate a digital representation of a product before it is physically built. Several techniques are employed in virtual prototyping to simulate various aspects of the product’s behavior, performance, and characteristics. Here are some common techniques:
Computer-Aided Design (CAD): CAD software is used to create detailed 3D models of the product’s geometry. These models serve as the basis for further analysis and simulations.
Finite Element Analysis (FEA): FEA is a numerical technique used to analyze how structures and materials behave under different conditions, such as stress, heat, and vibration. It helps predict how the product will perform under various loads and environments.
Computational Fluid Dynamics (CFD): CFD simulates the behavior of fluids (liquids and gases) and their interaction with solid surfaces. It is used to analyze airflow, heat transfer, and other fluid-related phenomena within or around the product.
Multibody Dynamics (MBD): MBD simulates the motion and interaction of multiple interconnected rigid or flexible bodies. It helps understand the mechanical behavior of complex systems, such as machinery and vehicles.
Virtual Reality (VR): VR technologies allow designers and engineers to immerse themselves in a virtual environment where they can interact with and manipulate digital prototypes in real-time. This enables better visualization and evaluation of the product’s design and functionality.
Simulation Software: Various specialized simulation software packages are available for specific industries and applications, such as automotive, aerospace, electronics, and healthcare. These software tools simulate specific aspects of the product, such as electromagnetic behavior, thermal performance, and structural integrity.
Optimization Algorithms: Optimization algorithms are used to automatically search for the best design parameters that meet specified performance criteria. They help optimize the product’s design for factors like weight, cost, strength, and efficiency.
Prototyping Platforms: Virtual prototyping platforms provide integrated environments where designers and engineers can collaborate, iterate, and validate their designs using a combination of simulation, visualization, and analysis tools.

Cad Design

If you think the idea of having driverless cars on the roads seems dangerous and utopian, think again, because the idea is quickly becoming reality. Actually, we have been using certain features of driverless cars for some time. Until recently, automobiles did not have cruise control, automatic and antilock braking, temperature sensors, GPS technology, or road sensing technology. That has all changed.[/fusion_text][fusion_text]The autopilot system for air travel has been available for a long time, and the maturity and reliability of the technology continue to improve. If automatic piloting of complex aircraft in busy airspaces is acceptable, why should driverless cars not be acceptable?

Car Cad Designs

A partial list of technologies required to create driverless cars are the following:

  • Onboard computer technology,
  • Onboard telemetry (radar and laser sensors),
  • Anti-lock and automatic braking systems,
  • Adaptive cruise control,
  • GPS and sensor technology,
  • Traction and stability control,
  • Automatic engine control,
  • Computerized navigational system.

This article focuses on CAD-related technologies which could be involved in building driverless cars. Specifically, the article discusses how the following technologies (which involve CAD design) will affect driverless cars:

  • The role of sensors, GPS technology, and video cameras for driverless cars,
  • Leading players in the development of driverless cars,
  • Benefits which driverless cars will provide,
  • Problems which driverless cars could create.

The role of sensors, GPS technology, and video cameras for driverless cars

The following technologies will help implement driverless car technology while providing collision avoidance and traffic safety:

  • Video cameras will detect traffic lights, read road signs, keep track of neighbouring vehicles, and look out for pedestrians, pets and other obstacles.
  • LIDAR (Laser Illuminating Detection and Ranging) sensors will detect edges of roads and identify lane markings by bouncing light pulses off the car’s surroundings.
  • Ultrasonic non-contact sensors in the wheels will detect the position of curbs and neighbouring vehicles during parking.
  • GPS technology will use the location of the vehicle to determine routing, speed limits and to provide navigational guidance.
  • Onboard telemetry will enable cars to communicate with one another, and with traffic monitoring and control systems.
  • The onboard computer will analyze all monitored and measured data in order to make navigational decisions regarding steering, acceleration or deceleration, and braking.

Leading players in the development of driverless cars

It is not within the scope of this article to list the names and accomplishments of all leading players in driverless car technology. It will suffice to highlight two significant accomplishments. Israel’s Mobileye® made news recently when its driverless vehicle supplied by Delphi Automotive traversed a 3,000-mile journey from San Francisco to Manhattan in 9 days. Before this accomplishment, the driverless vehicle had been successfully operated in Los Angeles and Las Vegas. The driverless vehicle could detect cyclists, debris on the road, curbs, barriers, construction zones, traffic lights, and road signs.
Mobileye expects to offer 237 driverless car models by the end of 2016.
Deals to use the technology have already been made with BMW, Chrysler, Ford, General Motors, Nissan, Peugeot, Volvo and Tesla. Truck manufacturers MAN SE, Scania, and IVECO have also made deals to use the technology.
In 2014, Google unveiled the technology named “Google Chauffeur” for piloting autonomous or driverless cars. Google’s technology neither uses a steering wheel nor a brake pedal.
Automotive companies which have signed on to use Google’s technology include Toyota Prius, Audi TT, and Lexus RX450h. Google’s robotic car uses a LIDAR system which generates a detailed local map of its environment. The generated map is combined with high-resolution maps of the world in order to produce data models that the computer uses to pilot the vehicle.
Google’s driverless vehicles have been tested in the San Francisco area, and they have logged about 700,000 miles (1.1 million km) of accident-free driving. Google plans to make its driverless cars publicly available by 2020.

Benefits which driverless cars will provide

In order to enjoy the benefits that driverless cars will provide, it is necessary for legislative bodies to pass or modify traffic laws. In the United States, the District of Columbia and four states have already passed laws that permit the operation of driverless cars. Many other state legislatures are discussing the passage of similar laws.

Predictably, the public will initially be sceptical about operating driverless cars, until the following benefits become evident.

  • There will be a significant reduction in vehicle collisions, injuries caused by automobile accidents, and loss of life. Consequently, the cost of insuring motor vehicles will be lower.
  • There will be less need for individual driving licenses and driving skills.
  • Senior citizens, teenagers, and handicapped people will have the mobility that they do not now have.
  • A businessman or woman could work or play (read the newspaper or a book, watch TV, eat or drink) instead of focusing on driving to work. The need for police officers to arrest motorists for DUI, which is a leading cause of traffic deaths, will be gone.
  • Law enforcement will have more manpower to fight crime instead of enforcing traffic laws.

Problems which driverless cars could create

It should not come as a surprise that whenever new technology is introduced to benefit mankind, criminal minds will find ways to misuse the technology for personal profit or to cause mischief. What problems could arise?

  • Criminals will hack into onboard computer systems in order to steal automobiles.
  • Terrorists will hack into traffic control systems and into car computer systems in order to create accidents, traffic jams, or chaos.

Law enforcement will need the training to fight these new types of traffic crime. The use of the internet, GPS, and drone technology could become useful instruments for enforcing traffic safety.

Conclusions

Driving as we know it is about to change in a dramatic way. Although many technical problems remain to be solved, the use of driverless vehicles should accelerate rapidly by the year 2020.

Initially, driverless cars will be expensive. When the costs of these vehicles come down, almost everyone (including senior citizens, children, drunk drivers, and even blind people) will have the privilege of using driverless cars without endangering the lives of the public or themselves.

The majority of people born before the 1900 year haven’t lived past 50 years of age. In the 20th century, life expectancy increased dramatically. Today, the life expectancy is over 80 years in several developed countries.

For over 85 years, people have been estimated to comprise about 8% of the total world population. Furthermore, the cost of health care continues to rise, and expect a large number of health care that could stress the health care systems of several nations.

Although it’s welcome news that increases life expectancy, living to a good old age. There won’t be any means without a good quality of life. Old, diseased or disabled poor senior citizens create burdens for home and caregivers. It increases the health care cost and insurance for the entire population.

The one way to maintain a good quality of life for the elderly is to find efficient and inexpensive methods to monitor their health. Doing so makes it take preventive measures to combat diseases and treat diseases and ailments before it becomes difficult and expensive to handle.

The following adds a partial list of steps that have been taken to increase life expectancy:

  • It reduces the transmission of infectious and parasitic diseases.
  • They immunize against polio, smallpox, measles, and major childhood diseases.
  • Supports improving living conditions by offering clean water and nutritious diets.
  • It offers health awareness and education to minimise exposure and other health risks. It includes toxic substances, alcohol, smoking, poor diet, with lack of exercise.
  • It includes funding the developmentof advanced drugs to fight and treat diseases.
  • It provides health monitoring, injury control and health management.

The last item, “offer health monitoring, health management and injury control”, uses modern CAD-related technology that forms wearable medical devices and focuses on this article.

In the article, we’ll get answer these questions:

  • What are wearable medical devices?
  • In what ways are wearable used in medical devices CAD-related?
  • Which wearable medical devices are commonly used?
  • What trends are likely to use wearable medical devices? 

What are Wearable Medical Devices CAD Design?

Wearable medical devices are biosensors attached to the body to monitor physiological data. It usually uses remote or wireless communication. As these devices are wearable, they provide 24/7 medical data to physicians that help to deliver easy health care.

Examples:

  • A small shirt worn by athletes to measure heart rate offers vital physiological data that is analyzed and used for training.
  • A pulse oximeter is mainly worn on a finger to measure pulse rate and blood oxygen saturation reliably.
  • Wearable blood pressure monitors the arm’s worn to measure blood pressure and heart rate.

IN WHAT WAYS ARE WEARABLE MEDICAL DEVICES CAD DESIGN-RELATED?

One essential role that CAD technology plays in creating wearable medical devices includes Additive Manufacturing or 3D printing wearable items. Let’s say a Swedish company, Decomed Design, works with CAD engineers, designers, IT professionals, and physicians to create stylish 3D printed wearable medical devices called an Akufeel bracelet.

The bracelet comes with an anti-nausea device worn on the wrist. The device offers pressure to an acupressure point from the inside of the wrist to relieve nausea symptoms. It could arise due to pregnancy, motion sickness, the flu, side effects of medication, etc.

With the stylish nature of the bracelet, the wearer could be happy to add adornment to their attire while enjoying an improved life quality.

Additive Manufacturing mainly creates wearable medical devices in shoes, vests, hearing aids, implants, prosthetics, and more. 

WHICH WEARABLE MEDICAL DEVICES ARE IN MOST COMMONLY USED?

The majority of easy to design wearable medical devices could measure activity and exercise. It includes calorie-burn rate, heart rate, blood pressure, or distance walked. Also, wearable computers, smartwatches, and smart clothing provide measurements. One needs to have an interest in building sophisticated wearable medical devices. These devices help monitor complicated physiological functions such as brain activity, EKG, glucose levels, hydration, oxygen level, temperature, sleep, and several other vital functions. The scope of this article provides an exhaustive list of wearable medical devices. It’s worthwhile to name a few of them.

Zephyr® manufactures a bio-data logger called Zephyr BioHarness, which monitors posture, activity, breathing, and ECG. It can transmit data within a 10-meter range, which is helpful for Remote Patient Monitoring. The Medtronic® manufactures cover FDA approved CGM (Continuous Glucose Monitor) and a diabetes management system that includes an insulin pump. Additionally, Omron® manufactures an FDA-approved pain relief device for the lower back, arm, leg, or foot. 

WHAT TRENDS ARE LIKELY FOR THE USE OF WEARABLE MEDICAL DEVICES?

A breakthrough wearable device offer emerges controlling diabetes. It helps in research work performed at UC San Diego’s Center for Wearable Sensors. The researchers develop wearable medical devices that work by measuring chemical markers. It includes potassium or lactic acid levels present in sweat or saliva.

The wearable blood glucose level monitors the devices that extract interstitial fluid below the skin to the surface. There’s no penetration of the skin to measure blood glucose levels.

Expect regulatory bodies, including FDA and establish well-defined guidelines on the manufacture. It uses wearable medical devices. Wearable medical devices come with a failure mode caused by chemical reactions between the device and the skin, poor wireless communication, battery safety, or electric shocks.

Failure mechanisms become well understood. It covers reliable and wearable medical devices. It is manufactured with predictable and dependable lifetimes. Its data transmission protocols and device reliability become robust, patient care with depending heavily on the use of wearable medical devices. Thus, healthcare costs reduce fewer patients confined to hospital beds.

CAD Innovations in Rapid Prototyping

Rapid Prototyping offer advanced ability to design and fabricate models. Along with using proof-of-principle prototypes. Whereas in some cases, it uses functional components. Also, it adds well-established Additive Processes, whereby plastic parts are mostly built layer by layer directly from a 3D CAD model. Some of the standard techniques include:

Stereo Lithography (SLA)

Selective Laser Sintering (SLS)

Direct Metal Laser Sintering (DMLS)

Fused Deposition Modelling (FDM)

The Polyjet Process

Computer Numeric Control (CNC) machinery mainly uses a well-known subtractive process and uses machines, billets and other desired parts. Whereas on the other hand, it uses rapid prototyping processes that cover Injection Moulding and Casting. It uses master moulds that inject cast plastic or any other urethane parts.

Several methods, techniques, and approaches are used that add rapid prototyping parts. It includes components that are developed each year. Some of the most exciting developments are shown below:

(CAD Innovations in Rapid Prototyping) FORD’S F3T RAPID STAMPING PROCESS

Ford Motor Company mainly uses sheet metal parts that assemble vehicles and develop world-renowned sheet metal fabrication. The process that takes a new design from a CAD model to a prototype can be time-consuming.

The latency increases the design iteration time, makes it highly cumbersome and excellent off prototypes and test-fit new designs. Recently, ford created a new rapid process, which they call the Ford Freeform Fabrication Technology (F3T). It’s a part of a three-year, $7.04 M, U.S. The department of Energy-funded effort mainly uses next-generation manufacturing and energy-efficient processes. The new short-run stamping technology offers low costs with fewer delivery times for low-quantity run sheet metal parts.

The process mostly begins with a CAD model, which creates a Computer Numeric Control (CNC) tool path and works similar to the path. It is used by a 3D printer with generating the part. It directs position with keeping in-depth dual-arm robot. It holds tools in both arms as the process sheets into shape. Additionally, it allows prototypes and small production that run cost-effectively with shorter lead times. The customization comes with viable design cost iterations, and it offers drastically reduced change. The short-run stamping process is used with bigger applications in various industries.

(CAD Innovations in Rapid Prototyping) LARGE-SCALE 3D PRINTERS

It’s a kind of exciting area of innovation used in rapid prototyping. It uses 3D printers for building models and working prototypes which were impossible until now. The 3D printers are capable of printing vehicles and provide tiny houses. The researchers at the Oak Ridge National Laboratory and Cincinnati Incorporated developed a printer capable of using Additive Processes by building the Stratis Car. The machine, named Big Area Additive Manufacturing (BAAM), makes a volume of 7′ x 13′ x 3′ along with a deposition rate of 40 lbs/hr against BAAM’s rate of 40 lbs/hr. The system supports to combines 3D printing along with CNC routing with the largest high-quality 3D printing. Also, the second generation of this technology, referred to as Bertha, feature a volume of 8′ x 20′ x 6′ and a 100 lbs/hr deposition rate.

The other researchers develop technologies that revolutionize the housing industry by using Additive Manufacturing and building structures. Massimo Moretti devoted his time by applying 3D printer technologies and providing rapid prototype solutions. It caters to the housing crisis in developing countries across the world.

Additionally, the project is known for the World’s Advanced Saving Project (WASP). It mimics the construction method of the Mud Dauber Wasp building its nest. The primary goal of the technology is to build houses that add no cost by using materials. They are readily available on-site in third-world countries.

The complete system is designed with two people that assemble a 3D printer within 2 hours. The researchers at Winsun New Materials allow China to spend USD 3.2M over 12 years by developing an enormous 3D printer.

The printer measures a whopping 6.6m tall, 10m wide and 150m long. The houses print layer by layer using a mixture of cement and glass fibres. It helps to create a solid composite structure. Recently, Winsun proved that it built ten houses of 200 square meters in size using recycled construction and industrial waste in less than a few hours at the cost of only $4,800 each. 

3D PRINTED JET ENGINES

The scope of 3D printing has been confined to housing. It has extended to jet engines, which are extremely difficult to build, including many intricate parts machined from many features with high tolerances for a seamless assembly.

The researchers at the Monash Centre comes with an Additive Manufacturing. Australia has produced the first 3D printed jet engine. It is based on an auxiliary powered gas turbine engine from Safran, a French aerospace firm. The Monash Centre mainly uses Concept Laser’s X line 1000R 3D printer. A state-of-the-art industrial printer fabricates components from metal powder by using sizes up to 60cm x 40cm x 50cm.

Whatever your proof-of-principle prototype requires. It is a suitable rapid prototype method that exists by adding CAD model and material/finish selection that the Software delivers. STP files enable customers by bringing ideas to life. We at Australian Design and Drafting help individuals and companies alike in this endeavour. The possibilities come endless as the technology becomes more viable and extends large sheet metals.

The architect developed a stunning 3D printing models

We have seen examples that prove that CAD design would be combined with 3D printing and produce fantastic artworks. It’s like a Turkish architect named Daghan Cam, and it depends on the software creation of art projects. It helps in computer simulation technology, primarily based on advanced algorithms. The robot creates an image processing training with a highly artistic 3D printed structure.

Architect developed a stunning 3D printing models

Daghan Cam is a pretty different architect. He founded his namesake architectural design company is based in London and Istanbul. At the University of London Bartlett School of Architecture faculty. Before this, he worked with famous architect Zaha Hadid, who worked and taught worldwide. In 2012, he receive an honorary Master of Architecture Degree with Distinction. Overall, Daghan Cam is a computational design, mechanical engineering and large-scale 3D printing specialist areas.

three dimensional design

From his architectural design, one can read keywords. One can see from the chart of the design model. It’s the essence design for futuristic and the Sydney Opera House. It is combined with the Milan Design Week to offer wide attention. Cam developed a GPU computing technology and algorithms combined to create fantastic and impressive models. The so-called GPU computing provides an app that calculates the part by heavy-handed GPU processing. It offers the remaining program in the CPU that is on the method. The method achieves unprecedented application performance.

The 3D printing effects comes with its unique programming through image processing robots. The team spent several years using a CUDA parallel programming model using NVIDIA GPU coded to develop these robots.

three dimensional design

Specifically, Cam design week offers an architectural model that use Quadro K6000 graphics and Tesla K40 GPU accelerators to support low accomplished superior computing power. The devices make the algorithm more sufficient to support such a gorgeous 3D shape creation. The Boston Corporation and Belgium 3D print vendors Materialize use the world’s largest stereolithography 3D printer. It prints the overall model time. You might ask that it’s a modern aesthetic that has become an actual building? As a senior architect, the answer is that it uses the least number of materials to reduce construction costs and add structural integrity.

3d printing models

After the great success of Milan, the Bartlett School of Architecture supports the application of technology to its wider range of projects. The large-scale 3D print manufacturing technology and robotics optimize deep learning algorithms for real-time image processing and robotics.

3d printing models

You need to develop a robot construction technology to effectively build these structures with its own decisions. Some of them still rely on NVIDIA cuDNN and its deep neural network library. Industrial manufacturing robots are mainly used for training.

Finally, Cam explains: “It’s just a prototype or artwork that can be used in the construction industry. It aims to explore the creative fidelity conversion process from intention-to information processing.” It is used as 3D printing innovation to use in the construction industry.

What is a 3D printing model?

A 3D printing model, also known as a digital model or a 3D model, is a virtual representation of a physical object created using computer-aided design (CAD) software or acquired through 3D scanning techniques. These models are typically stored in digital file formats such as STL (stereolithography) or OBJ (object) files.

The 3D printing model contains all the necessary geometric information required to produce the object layer by layer using a 3D printer. This information includes the shape, dimensions, and often intricate details of the object.
Once a 3D printing model is created or obtained, it can be sent to a 3D printer, which interprets the digital information and constructs the physical object by depositing or solidifying material layer by layer according to the specifications outlined in the model.

How do I print a 3D model?

Printing a 3D model involves several steps, but here’s a basic guide to get you started:
Choose or Create a 3D Model: You can either design your own 3D model using CAD software like Tinkercad, Fusion 360, or Blender, or you can download a pre-made model from various online repositories like Thingiverse, MyMiniFactory, or GrabCAD.
Prepare the Model: If necessary, use slicing software to prepare the model for printing. Slicing software takes the 3D model and generates the toolpath instructions (G-code) that the 3D printer needs to create the object layer by layer. Popular slicing software includes Cura, Slic3r, and PrusaSlicer.
Load the Model into Slicing Software: Import your 3D model into the slicing software. Adjust settings such as layer height, infill density, and print speed according to your preferences and the capabilities of your printer.
Slice the Model: Use the slicing software to generate the G-code instructions for your specific 3D printer. This process divides the model into layers and calculates the paths the printer’s nozzle or laser will follow to create each layer.
Transfer G-code to Printer: Save the sliced G-code file to an SD card or connect your computer directly to the 3D printer if it supports USB connectivity. Transfer the G-code file to the printer.
Prepare the Printer: Ensure that your 3D printer is properly calibrated, and the print bed is clean and level. Load the filament (or resin, in the case of resin printers) into the printer according to the manufacturer’s instructions.
Start Printing: Use the printer’s interface to select the G-code file you transferred earlier. Start the printing process, and the printer will begin creating your object layer by layer.
Monitor the Print: Keep an eye on the print throughout the process to ensure everything is proceeding smoothly. Address any issues that arise, such as filament jams or adhesion problems.
Remove the Print: Once the print is complete, carefully remove it from the print bed. Depending on the type of printer and material used, you may need to use tools like a scraper or spatula to assist in removing the object.
Post-Processing (Optional): Depending on your preferences and the requirements of your print, you may need to perform post-processing tasks such as sanding, painting, or assembly to achieve the desired final result.
