What is Computer Aided Engineering (CAE)

COMPUTER AIDED ENGINEERING (CAE)

    Computer-Aided Engineering (CAE)

    Computer-aided engineering (CAE) is the method of using computers in design, analysis, and manufacturing of a product, process, or project. CAE relates to most elements of CADD in industry. CAE is often recognized as the umbrella discipline that involves several computer-aided technologies including but not limited to, CAD, computer-aided industrial design (CAID), CAD/CAM, CNC, CIM, and PDM, plus the Internet and other technologies to collaborate on projects.
    CAE often focuses on mechanical design and product development automation. Some of the most familiar elements of CAE are surface and solid modeling and the simulation, analysis, testing, and optimization of mechanical structures and systems using digital prototypes. FEA is a process often associated with CAE.

    DESIGN APPLICATION

    Computer-aided design and drafting (CADD) and related computer-aided technologies offer revolutionary tools for engineers and drafters to use during the engineering design process. CADD enhances design creativity, efficiency, and effectiveness when appropriately applied to product development. There are many different forms of accepted engineering design processes and integration of CADD within the engineering design process.

    Computer-Aided Engineering (CAE)

    The figure shows a simplified sample of an engineering design process for a lift hook. The lift hook example and the following information is an introduction to CADD in the engineering design process.

    STEP - 1

    Step 1 is to identify the problem and design constraints. A constraint is a condition, such as a specific size, shape, or requirement, that defines and restricts a design and must be satisfied in order to achieve a successful design. The problem statement in Figure, Step 1 describes the requirements and constraints for a forged-steel lift hook able to support a 3000-pound load.

    STEP - 2

    Step 2 is to sketch an initial design according to a possible solution to the problem. The sketch in Figure, Step 2, is hand-drawn. You can use CADD as a sketching tool, and some CADD systems require you to create a digital sketch as an element of the CADD process. However, hand-drawn sketches are
    common practice, especially during early design.

    STEP - 3

    Step 3 is to generate the initial three-dimensional (3-D) computer-aided design (CAD) solid model according to the hand-drawn sketch. You can now study the model using finite element analysis (FEA) software. FEA applies the finite element method (FEM) to solve mathematical equations related to engineering design problems, such as structural and thermal problems.

    STEP - 4

    The figure, Step 4 shows a structural stress analysis applied to the lift hook to simulate a real-world lift.

    STEP - 5

    Step 5 is to optimize the design to reduce material and improve shape while maintaining an acceptable working strength. You can perform design optimization using manual calculations and tests, repeated FEA simulation, or design-optimization software. The figure, Step 5 shows the optimized lift hook CAD solid model.

    STEP - 6

    Step 6 is to reanalyze the model to confirm a solution to the design problem.

    STEP - 7

    The final step 7 is to use the CAD solid model to prepare two-dimensional (2-D) detail drawings and a digital format of the model supported by computer-aided manufacturing (CAM) software. The manufacturer uses the supplied data to create the forging equipment necessary to produce the lift hook.

    PROFESSIONAL APPROCHED

    A wide variety of jobs are available for qualified CADD professionals. Keep in mind that the kinds of tasks may not always be traditional drafting functions. In addition to creating drawings, you can be responsible for working in some of the following areas:

    • Preparing freehand sketches on the shop floor or at a job site and then converting the sketch to a finished CADD drawing.
    • Digital image creation and editing.
    • Text documents such as reports, proposals, and studies.
    • Incorporation of CADD drawings and images into text documents.
    • Conducting research for job proposals, feasibility studies, or purchasing specifications.
    • Evaluating and testing new software.
    • Training staff members in the use of new software or procedures.
    • Collecting vendor product information for new projects.
    • Speaking on the phone and dealing personally with vendors, clients, contractors, and engineers.
    • Checking drawings and designs created by others for accuracy.
    • Researching computer equipment and preparing bid specifications for purchase.

    Human-resource directors who most often hire employees agree that persons who possess a set of good general skills usually become good employees. The best jobs are found by those students who have developed a good working understanding of the project planning process and can apply it to any situation.

    The foundation on which this process is based rests on the person’s ability to communicate well orally, apply solid math skills (through trigonometry), write clearly, exhibit good problem-solving skills, and know how to use resources to conduct research and find information. These general qualifications also serve as the foundation for the more specific skills of your area of study. These include good working knowledge of drawing layout and construction techniques based on applicable standards and a good grasp of CADD software used to create drawings and models.

    In addition, those students who possess the skills needed to customize the CADD software to suit their specific needs may be in demand. What is most important for the prospective drafter to remember is the difference between content and process. This was discussed previously in this chapter but deserves a quick review. Content applies to the details of an object, procedure, or situation. Given enough time, you can find all of the pieces of information needed to complete a task, such as creating a drawing or designing a model.

    Process refers to a method of doing something, usually involving a number of steps. By learning a useful process, you will find it easier to complete any task and find all of the information (content) you need. It is beneficial to learn a good process for problem-solving and project planning that can be used in any situation. By using the process for any task, it becomes easier to determine what content is needed.

    For these reasons, it is strongly recommended that you focus your efforts on learning and establishing good problem solving and project-planning habits. These skills make the task of locating the content you need for any project easier and contribute to making all aspects of your life more efficient, productive, and relaxing.

    What is Engineering Prototyping

    What is Engineering Prototyping

    What is Engineering Prototyping

      PROTOTYPING

      A prototype is a functional part model of design; it is used as the basis for continuing the production of the final part or assembly. The terms prototype and model are often used interchangeably. Prototypes are used to determine if a new design works as intended. A prototype is commonly used as part of the product design process to enable engineers and designers to explore design alternatives, determine unknown characteristics in the design, finalize part tolerances, confirm customer interest in the design, verify design performance, coordinate with marketing and sales, and test theories before starting full production of a new product.
      A variety of processes can be used to create a prototype. The processes range from creating a digital model to developing a solid physical model of a part directly from a 3-D CAD model data and to fabricating a model using standard manufacturing processes. A company generally contracts with another company that specializes in developing prototypes quickly and accurately. Some companies have their own prototype development departments. A prototype is generally different from the final production part because special processes and materials are used to quickly create a part that can be used to simulate the actual part.
      The development phase of the design process is when a fully functioning prototype model is made that operates at the desired quality level. A physical prototype can be machined, molded, or created using rapid prototyping processes. Parts are assembled into the desired product and then tested to determine if the design meets specifi c product requirements such as weight and performance. The design might have to return to the concept phase for reevaluation if some aspects of the design do not perform as intended or manufacturing process appears to be too costly. After the functioning prototype has been built and tested, drawings are created for continuing to full production of the product.

      DIGITAL PROTOTYPING

      digital prototyping model

      A digital prototype is a computer-generated model or original design that has not been released for production. The most common and useful digital prototype is a 3-D solid model. A solid model digital prototype functions much like a physical prototype, is often just as or even more accurate, and can be subjected to real-world analysis and simulation. Digital prototyping is the method of using CAD to help solve engineering design problems and provide digital models for project requirements. Successful digital prototyping offers several ben-efi ts to the engineering design process. It provides companies with a deeper understanding of product function, enables the simulation of product performance as part of a complete system, offers interactive and automatic design optimization based on requirements, and assists other areas of product development and coordination.
      Digital prototyping can support all members of a product development team and help communication. Designers, engineers, and manufacturers use digital prototyping to explore ideas and optimize and validate designs quickly. Salespeople and marketers use digital prototyping to demonstrate and describe products. Depending on product requirements and company practices, digital prototyping can reduce or eliminate the need for physical prototypes, which are often expensive and time-consuming to create and test. The figure shows an example of digital prototyping to model, analyze, simulate, and visualize products in a virtual environment.

      RAPID PROTOTYPING

       

      rapid prototyping model

      Rapid prototyping is a manufacturing process by which a solid physical model of a part is made directly from 3-D CAD model data without any special tooling. An RP model is a physical 3-D model that can be created far more quickly than by using standard manufacturing processes. Examples of RP are stereolithography (SLA) and fused deposition modeling (FDM), or 3-D printing.
      Three-dimensional CAD software such as AutoCAD, Autodesk Inventor, NX, Pro/Engineer, and SolidWorks allows you to export an RP fi le from a solid model in the form of a .stl file. A computer using postprocessing software slices the 3-D CAD data into .005–.013 in. thick cross-sectional planes. Each slice or layer is composed of closely spaced lines resembling a honeycomb. The slice is shaped like the cross-section of the part. The cross-sections are sent from the computer to the rapid prototyping machine, which builds the part one layer at a time.
      The SLA and FDM processes are similar, using a machine with a vat that contains a photosensitive liquid epoxy plastic and a flat platform or starting base resting just below the surface of the liquid as shown in Figure. A laser-controlled with bi-directional motors is positioned above the vat and perpendicular to the surface of the polymer. The first layer is bonded to the platform by the heat of a thin laser beam that traces the lines of the layer onto the surface of the liquid polymer. When the first layer is completed, the platform has lowered the thickness of one layer. Additional layers are bonded on top of the first in the same manner, according to the shape of their respective cross-sections. This process is repeated until the prototype part is complete.
      Another type of rapid prototyping called solid object 3-D printing uses an approach similar to inkjet printing. During the build process, a print head with a model and support print tip create the model by dispensing a thermoplastic material in layers.

      The printer can be networked to any CAD workstation and operates with the push of a few buttons as shown in Figure.
      Rapid prototyping has revolutionized product design and manufacture. The development of physical models can be accomplished in significantly less time when compared to traditional machining processes. Changes to a part can be made on the 3-D CAD model and then sent to the RP equipment for quick reproduction. Engineers can use these models for design verification, sales presentations, investment casting, tooling, and other manufacturing functions. In addition, medical imaging, CAD, and RP have made it possible to quickly develop medical models such as replacement teeth and for medical research.

      RAPID INJECTION MOLDING PROTOTYPING

      rapid injection molding prototyping by rapid injection molding rapid injection molding protoryping

      Rapid injection molding is an automated process of designing and manufacturing molds based on customer-supplied 3-D CAD part models. Because of this automation, lead time for the initial parts is cut to one-third of conventional methods. Cost-saving varies with the number of parts being produced, but rapid injection molding can also have a substantial cost advantage in runs of up to thousands of parts. Rapid injection molding produces quality molds using advanced aluminium alloys and precise, high-speed CNC machining. Parts can be molded in almost any engineering-grade resin. The figure shows the 3-D CAD part model, the injection molded part in the mold, and the resulting rapid injection molded part.

      SUBTRACTIVE RAPID PROTOTYPING

      Subtractive Rapid Pr ototyping

      Subtractive Rapid

       Rapid Prototyping Subtractive

      CNC machining of parts has been around for decades, but the use has typically not been applied to short lead-time prototype development. Subtractive rapid prototyping uses proprietary software running on large-scale computers to translate a 3-D CAD design into instructions for high-speed CNC milling equipment. The result is the manufacturing of small quantities of functional parts very fast, typically within one to three business days. A variety of materials, including plastics and metal, can be used with sub-tractive rapid prototyping. The figure shows the 3-D CAD part model, the CNC machining process, and the machined part.

      CONVENTIONAL MACHINING PROTOTYPING

      Some companies have a machine shop combined with the research-and-development (R&D) department. The purpose of the machine shop is to create prototypes for engineering designs. Drafters generally work with engineers and highly skilled machinists to create design drawings that are provided to the machine shop for the prototype machining. This practice generally takes longer than the previously described practices, but the resulting parts can be used to assemble a working prototype of the product for testing.

      what is engineering Drawing

      WHAT IS THE ENGINEERING DRAWING

      Engineering drawing is the common language of engineering and describes the process of creating drawings for any engineering or architectural application. Engineering drawings, produced according to accepted standards and format, provide an effective and efficient way to communicate specific information about design intent. Engineering drawings are typically not open to interpretation like other drawings, such as decorative drawings and artistic paintings. A successful engineering drawing describes a specific item in a way that the viewer of the drawing understands completely and without misinterpretation.

      The term engineering drawing is also known as drafting, engineering drafting, mechanical drawing, mechanical drafting, technical drawing, and technical drafting. Drafting is a graphic language using lines, symbols, and notes to describe objects for manufacture or construction. Most technical disciplines use drafting, including architecture, civil and electrical engineering, electronics, piping, manufacturing, and structural engineering. The term mechanical drafting has alternate meanings. The manufacturing industry uses mechanical drafting, with its name derived from mechanisms. The construction industry also uses mechanical drafting, but the term refers to drafting heating, ventilating, and air-conditioning (HVAC) systems, which is the mechanical portion of an architectural project.

      Manual drafting is a term that describes traditional drafting practice using pencil or ink on a medium such as paper or polyester film, with the support of drafting instruments and equipment. Computer-aided drafting (CAD) has taken the place of manual drafting. CAD uses computers for drafting. CAD also refers to computer-aided design when computers are used to design.

      Engineering drawings communicate a variety of concepts, such as engineering requirements, instructions, and proposals, to a variety of people, such as the many different individuals often involved with a project. An engineering drawing or a complete set of engineering drawings provides all of the data required to manufacture or construct an item or product, such as a machine part, consumer product, or structure.

      ENGINEERING DRAWINGStudy the drawing of the medical instrument part in Figure. The drawing completely and unmistakably describes the size and location of all geometric features, and it identifies other characteristics of the part, such as material and manufacturing precision and processes. The medical instrument company uses the drawing to share and document design intent and to manufacture the part. Consider how difficult it would be to explain the part without the engineering drawing.

       

      ENGINEERING DRAWING AUSTRALIAThe figure shows another example of an engineering drawing, an architectural drawing for a home-remodelling project.

      This engineering drawing is an architectural drawing for a home-remodelling project. The drawing is one sheet in a set of drawings that communicates architectural style, the size and location of building features, and construction methods and materials.

      The drawing is one sheet in a set of drawings that communicates architectural style, the size and location of building features, and construction methods and materials. The set of drawings is also required to obtain a loan to pay for construction, to acquire building permits to legally begin construction, and to establish accurate building cost estimates. Usually, it is legally impossible and certainly impractical to begin construction without engineering drawings.

      Computers in Design and Drafting

      The use of computers has revolutionized business and industry process, including design and drafting practices. Computer-aided design and drafting (CADD) is the process of using a computer with CADD software for design and drafting applications. Software is the program or instructions that enable a computer to perform specific functions to accomplish a task. CAD is the acronym for computer-aided design, but CAD is also a common reference to computer-aided drafting. Computer-aided design and computer-aided drafting refer to specific aspects of the CADD process. The use of CADD has made the design and drafting process more accurate and faster. Several industries and most disciplines related to engineering and architecture use CADD. Most engineering firms and educational institutions that previously used manual drafting practices have evolved to CADD.

      CADD allows designers and drafters to produce accurate drawings that are very neat and legible and matched to industry standards. CADD can even produce architectural drawings, which have always had an artistic flair with lettering and line styles, to match the appearance of the finest handwork available. In addition, CADD drawings are consistent from one person or company to the next. CADD enhances the ability for designers and drafters to be creative by providing many new tools such as solid modelling, animation, and virtual reality.

      difference between IGES and STEP Files

      What is difference between IGES and STEP Files?

      What is difference between IGES and STEP Files?

      • Both are "neutral file formats". They were developed to be compatible with different 3D packages
      • The oldest is IGES (Initial Graphics Exchange Specification). It was developed in the mid '70s by the defense industry to solve compatibility issues between different software packages
      • STEP (Standard for the Exchange of Product data) was created in the '80s by ISO as an improvement on IGES
      • The most widespread format is IGES but it can only contain basic 2D or 3D data
      • STEP is more versatile and contains additional information such as material information and tolerances

      For most design engineers, the following scenario should look familiar: Peter, the lead designer for company X, needs to send a CAD model to Mary, the design engineer for company Y. Peter designed the part using Solidworks and Mary only works in Pro Engineer. Peter’s Solidworks file can’t be opened in Mary’s software, so the simple transfer of a part file has now become a problem.

      This issue of non-interchangeable proprietary file formats for CAD data has been around for decades. Software companies want to promote the use of their own modeling packages, and one way to do this is to ensure that only their package can open a file created in their software. Unfortunately, every major 3D modeling software company has done this, so communicating between them is a problem.

      Luckily, a solution exists in the form of neutral file formats. A neutral file format is one that can be passed between different modeling software packages. Bob could use a neutral file format to pass his CAD model to Susan, who could then open it and work with it as needed.

      The most common variants of these neutral file formats are the IGES (pronounces eye-jess) and STEP formats. You can recognize these formats because the file name will end in .iges, .igs, .stp, or .step.

      The History of Neutral file Formats

      In the mid-seventies, the United States government realized that it had a problem. With all of the unique proprietary CAD programs used by its different contractors, millions of dollars and countless hours were wasted on the tedious process of sharing and converting data between all the systems. You can imagine how many times this scenario played out on a large project like an aircraft carrier or missile delivery system with hundreds of suppliers!

      So, the Air Force launched a project in conjunction with Boeing and several other large industry partners to create a neutral file format. The result was IGES (Initial Graphics Exchange Specification), which is a flexible file format that codifies drawing, 3d geometry, and other critical CAD data in a format that can be shared between all major CAD systems.

      Since the eighties, the US Department of Defense has required that the IGES format be used for all weapons and defense contracts, and it has been adopted in other industries as well.

      STEP (Standard for the Exchange of Product data) was created in the eighties as an improvement on the IGES standard by ISO (the International Standards Organization), with the goal of creating a global standard for a range of CAD-related data types. Due to the complexity of the undertaking, it has taken years of development and is still being continuously upgraded. It is currently the largest of all of ISO’s standards.

      Difference Between IGES and STEP

      IGES is the most widespread standard, and is supported by nearly all major CAD systems worldwide.

      An IGES file contains basic CAD information:

      • 2D and 3D geometry (curves, surfaces, and wireframes)
      • Presentation elements (drafting elements like lines and annotations)
      • Electronic and pipe schematic elements
      • Finite element modeling elements
      • Language and product definition data

      STEP is a newer standard, and is therefore not as widespread as IGES. However, most major CAD programs recognize STEP and its ubiquity is steadily growing as the standard improves.

      STEP files contain the same product definition information as IGES, with the following additions:

      • Topology
      • Tolerances
      • Material properties
      • Other complex product data

      Practical Considerations

      In most cases where solid models or drawings are being shared, either file format will work fine. For compatibility it is safest to start with IGES, since it is the more common format and therefore more likely to work with the receiving party’s software.

      However, a designer should also consider the information being shared. If the file being sent needs to contain more product definition (for example, geometric dimensioning and tolerancing data, material properties, etc), then STEP would be a better choice.

      It is not uncommon for one supplier to have trouble working with one format, and to request its alternative. Depending on your industry and software, you will likely become familiar with one or the other and stick to it in most situations

      The New Dimension in Electrical Design Evolution or Revolution?

      how electrical engineers moved from paper sketches to 3d

      Hi Folks! Its chilling winter here in Australia, so let's have some warms up from electrical design and drafting news..

      Over the past 260 years, the way we light our homes and power our businesses has changed dramatically. We’ve traded candles for light bulbs, abandoned the abacus for super computers, and swapped selenium wafers for energy-efficient solar panels. We now have a generation of products that are connected to the internet to improve the quality of our lives–think smart appliances, fitness monitors, and intelligent trash cans.  These innovations reflect advances in scientific thinking—and advances in the way engineers design increasingly complex electrical design systems.

      1752: Lightning in a … Kite?electrical design

      Benjamin Franklin was an inventor, writer and statesman, but he was also an engineer who developed electrical systems using hand sketches. His best-known feat? Verifying that lightning is actually electricity.

      In June 1752, history says that Benjamin Franklin sent a key attached to a homemade kite into the air. “As soon as any of the thunder clouds come over the kite,” he wrote, “the pointed wire will draw the electric fire from them, and the kite, with all the twine, will be electrified.” While there’s a good chance Franklin made up the tale, his theory was ”electrifying.”

      1879: A Little Menlo Park Magic

      Picking up where Franklin left off, Thomas Alva Edison (aka the Wizard of Menlo Park) held more than 1,000 patents. In 1879, he introduced the electric light bulb. It lasted longer than previous models and employed a carbonized cotton thread filament.

      Edison made a host of other contributions to electrical design, including the system of power stations now called General Electric, and schematics continued to be the planning tool of choice.

      Although a true technological genius, Edison wasn’t all butterflies and rainbows— he electrocuted puppies, a horse, and an elephant in an attempt to label alternating

      current (AC) power as dangerous. He lost this campaign and Nikola Tesla’s AC induction motor won, mechanizing factory work and powering household solidworks electrical designappliances.

      But that (admittedly creepy) anecdote hardly tells the full story of Edison’s life. He went on to improve life for generations of Americans with the phonograph, motion pictures, the storage battery, and more.

      1907: Vacuum Tubes

      Throughout the 20th century, electrical engineers used schematics to represent increasingly complicated systems for radio, medical devices, and computers. In 1907, Lee De Forest patented the audion, which enabled clearly audible sounds such as a human voice to be relayed and amplified using a three-electrode vacuum tube–the world’s first triode.

      1929: Machine Packs Serious Voltage

      Wiring diagrams based on physical connections entered the electrical engineering vocabulary in 1929, when Alabama native Robert Jemison Van de Graaff built the first working model of an electrostatic accelerator.

      Its purpose: accelerate particles, break apart atomic nuclei, and unlock

      the secrets of individual atoms. Van de Graaff’s invention is used widely in science classrooms and paved the way for future electrical research.

      1947: Transistor Transition

      Schematics advanced yet again when electrical engineers began creating them based on logical connections. A major breakthrough occurred in 1947 when John

      Bardeen, Walter Brattain, and William Shockley collaborated to demonstrate the transistor— which amplifies or switches electrical signals—at Bell Laboratories. The semiconductor, which paired two gold contacts and a germanium crystal, represented an upgrade from cumbersome vacuum tubes.

      1977: We’ve Gone Digital!

      By the late 1970s, functions such as placement and routing became available in automatic physicalElectrical design Drawings

      electronic design automation (EDA)— marking the birth of the digital schematic. Bell Labs, along with companies such as IBM and RCA, held advanced tools that operated on mainframes or 8-bit minicomputers. In 1977, super minis provided massive amounts of memory for designs.

      Today: Entering a New Dimension

      For decades, companies have developed products that feature both mechanical and electrical components. The traditional product development process for an electromechanical product has created long design cycles due to sequential electrical and mechanical design, as well as the discontinuities which occur when different groups use different names for common elements.

      There are challenges in keeping the Bill of Materials (BOM) accurate through the use of so many spreadsheets. Often, once the electrical design piece has been completed,

      it is then handed off to the mechanical design team. After they complete their part of the design, the entertaining part happens when it comes to figuring out how the electrical pieces fit into the product. A physical prototype is built at this point and

      the designers get out a ball of string or a measuring tape to figure out how the wiring will fit. Given all the powerful software design tools we have, it’s ironic that we have fallen back to low-tech ways of integrating the electrical and mechanical pieces of the design. As you might expect, this method is prone to introducing lots of errors

      and delays into the production process, product documentation, and BOM.

      Things have evolved a bit over the last couple years. Electrical schematics entered the third dimension in 2012, when SOLIDWORKS introduced powerful and affordable 3D electrical CAD software for Windows, merging the logical connections championed by Benjamin Franklin with the modern day need to build 3D physical connections.

      Using SOLIDWORKS® Electrical software, you can easily design electrical schematics and transform the logical schematics into 3D physical models which integrate into the overall design. SOLIDWORKS Electrical 3D™ integrates with SOLIDWORKS 3D CAD modeling software to enable bi-directional and real-time integration of electrical components within the 3D model maintaining design synchronization and an accurate BOM. In this way, the entire engineering team can collaboratively work on a project concurrently, which not only produces a more integrated design; it can also lower project costs, and shorten time to market.

      Another benefit of the integrated SOLIDWORKS solution for electro-mechanical design is the ability to analyze or simulate the operation of the entire model against real-world conditions, such as thermal stress or physical vibration–all without having to build a physical prototype. This seems like “common-sense” (which even a man like Benjamin Franklin would appreciate if he were alive today).

      From light bulbs to intelligent trash cans—and from handwritten notes on paper napkins to 3D modeling—one thing is clear: electrical design has entered the next dimension.

      What You should know about Solidworks and its History?

      In the following article, I will describe you in short sentences the genesis of SOLIDWORKS. How did it happen and why SOLIDWORKS until today has been so successful.

      In December 1993, Mr. Jon Deer Tick founded together with a team of engineers SOLIDWORKS in Waltham Massachusetts / USA.His goal was to create a 3D CAD software (computer-aided design), therefore to develop a computerized program that volume body based modeling and to create technical drawings digitally. In addition, this software should be as user-friendly and do not require costly hardware.

      Deer Tick opted for the Windows platform, in the very successful release of Windows 95. He and his team developed and programmed over a year and came up with the "initial release" 1995th first edition.

      The friendly interface and intuitive handling of the parametric features made SOLIDWORKS quickly became popular. SOLIDWORKS was Distributed by certified resellers, offered in 1996 for the small machine builders in Germany at affordable prices and became the German success story.

      In 1997, the French software company Dassault Systèmes took notice of SOLIDWORKS success stories and bought it for 310 million US dollars. There were initial doubts by SOLIDWORKS users, whether Dassault SOLIDWORKS would be implemented in the CAD program Catia or would give up entirely, but the Dassault Systèmes quickly realized the potential of SOLIDWORKS and focused on its further development.

      Since SOLIDWORKS is continuously developed and expanded modularly. There are a variety of additional applications and industry-supporting functions. Such as the Sheet metal features or the weldment features.

      Currently SOLIDWORKS is worldwide, more than 3,073,600 licenses in 23,400 locations in 80 countries.

      fundamental issue with designer or drafter

      What are the Main fundamental Issues for 3d Designer/Drafter?

      There are some very confusing fundamental issues encounter by designer/drafter during design process and It should be address properly during process itself. If a 3d designer/drafter create his drawings separately from the production regardless of the manufacturing process, incurred costly and time-consuming delays.
      For example, if a drawing with incorrect dimensions or incorrect material properties given in the production, the drawing must be reworked with time consuming and the process flow is massively disrupted ,

      Therefore, make sure that your design and manufacturing work on a common basis, when it comes to integrating the entire process chain of product development. There are lots of intelligent 3d design and drafting software available for producing accurate manufacturing drawings. We will talk about Solidworks today.

      SOLIDWORKS provides you the answers to two important questions you should ask during the design process.

      1. Is this product financially feasible?

      The total cost of producing a product are influenced by a variety of factors, such as material and labor costs.This means that even a seemingly small change can have a large impact on the overall cost structure.

      SOLIDWORKS Costing helps you ensure that no cost-related surprises to come to you when your model goes into production. It allows 3d designer/drafter, project managers and the Engineers to pursue new product development. It gives clear cost perspective with regard to compliance with the pre-calculated structures that can be monitored and impact of changes are transparent and clear.

      Another advantage of SOLIDWORKS Costing is the ability to work with both original SOLIDWORKS models and drawings from other 3D CAD programs or neutral formats like IGES or STEP. The user can define different materials, make changes to drawings or relocate the place of manufacture. All changes to the model are displayed immediately in cost per piece.

      2. Can this product be manufactured?

      SOLIDWORKS supports 3d designer/drafter and mold makers with respect to the feasibility of your products by SOLIDWORKS Simulation . In the development process, there are complicated shape models that changing regularly. The export process and repair of data having high probabilities of error and often contain inaccuracies.
      For this reason, many mold makers tend to wait until the final design of a product is established and then only begin to develop final form. This costs valuable production time as well. Using SOLIDWORKS, mold makers can start early to make form. In addition, a correct form geometry including sketches audit and control of thickness and waste is ensured. For example, SOLIDWORKS Plastics can perform a detailed filling analysis and
      determine the optimum position of the injection points also SOLIDWORKS Plastics can ensure proper filling pattern of the component and tracking where form weld lines and if necessary, correct the injection points.

      3d designer/drafter can have complete product development process in SOLIDWORKS and ensure effective communication between design and production while the entire development process.

      Autodesk Inventor Intellectual Property

      How to Protect Design Intellectual Property with Autodesk Inventor?

      In the modern business world with millions of files coming and going in cyber space it is important for companies to protect their Intellectual Property (IP). This becomes even more important when manufacturing a product in which countless hours of engineer time has gone into, not to mention a company’s reputation if a “knockoff “product held to lesser standards hits the market. We have found that as industries go, we also may find the need to work with Architects or architectural design firms to bring solid mechanical models, such as boilers or mezzanines into Revit to represent placement, size or shape. Regardless of the situation we would like you to keep your Intellectual Property safe. This is why Autodesk has worked so hard to help you prevent this with Simplify in Autodesk Inventor, allowing the user to create a simple version for the consumer to use without giving them the real important design information. So please follow along as we help you learn this important tool and how it can help you.

      The Full Model

      Shown below, you can see in the section that I created in which there are internal items as well as external items that you may  not want the customer to have when providing them with a model for their planning purposes in autodesk.   They basically need the size    shape and maybe a few connection points. This can be done a couple of ways, the first is creating a shell of the original model        as a single part, and another is creating basic shapes to represent the model and the space it takes up.

      Autodesk Inventor

      Include  Components

      The First step to protecting your Intellectual Property is going to the Simplify tab and choosing which components to include. You  will do this with     the  Include  Components command.

      Inventor Intellectual Property

      After selecting Include Components a mini tool bar will open, allowing you to select various options from the drop down menu. The first drop down is what you will view. In the drop down you have the option of viewing all Components, Included Components, or Excluded Components. I find it most helpful to switch between the three viewing options while making my selections, allowing   for a review of any missing parts or parts that should not be included. I have shown in the screen captures below what each option does. The drop down option is for choosing Part, Component, or Parent Priority. After choosing your options and selecting what needs to be included, simply click the check mark to finish this part of the process.

      autodesk Inventor Intellectual Property

      View Master

      When you finish the Include Components portion you will notice that you can no longer see the items that were not included, and if we look at our View Master the command automatically created a view called Simple View 1 (example is shown below). We can also right click on this view in the browser to edit our selections.

      Intellectual Property Inventor

      Create Simplified Part

      The Third step is to select Create Simplified Part, this launches a new dialog box with the standard new part creation options  such as file save location and name, but also includes options for what type of part you create using the combine style buttons. The options are as  follows:

      • Single solid body with seems between faces merged
      • Single solid body with seems between faces  maintained
      • Maintain each solid as a separate body

      For our purposes I will choose the second option. You will now see the BIM tab is open for further simplification.

      Note: Simple View 1 must be the current view and I always create a Simple Folder for these simplified parts.

      Autodesk Inventor

      BIM Tab and Further Simplification

      At this point your model is simplified a great deal, but we can still simplify it more using the Simplify section of the BIM Tab.  We will cover the other half of the BIM Tab in my next   paper.

      Inventor Autodesk Intellectual Property

      Remove Details

      We will first look at the Remove details command, using this will remove recagnized fillets and chamfers as well as custom-  selected faces. It utilizes a mini tool bar for any of your options. When looking at the mini tool bar we have a few options for selecting items to remove. The All Faces Selectable allows us to select faces. We  also have a Fillet and Chamfer selection box (these will be selected by default). Our last Option is Auto Select. Please see the screen captures below to understand how  thease  options work.

      Intellectual Property Inventor

      Fill Voids

      The second option to further simplification is Fill Voids, this option fills holes and spaces with surface patches, leaving a smooth surface. Our options on this tool bar for selection besides the auto Select are Select Loop, Select Edge, or Select Face.

      See below to view how these tools   function.

      Intellectual Property Inventor

      Define Envelopes

      The third option to simplify the parts further is the Define Envelopes option, this option replaces a part or object with a solid object in the form of a cylinder or box. Our options on this tool bar are Bounding Box and Bounding Cylinder for our first button, Join or New Solid in the second button and our selection methods are faces and solid. See below for examples.

      Best CAD Drafting Software

      Computer-aided Drafting or simply CAD Drafting has wiped out and replaced almost all traditional hand drafting techniques used in many industries – especially within the realm of mechanical engineering and design. Neater and faster to conduct, computer-aided drawings are also fairly easy to modify and far less vulnerable to physical damages. For these sheer advantages, CAD drafting has become an essential standard for mechanical engineers to formulate comprehensive strategies about a product and its mechanical components as well as to demonstrate a visual illustration of how it needs to be constructed to allow a flawless and effective functioning. And need we say, in order to cash on the ever-rising popularity of these drafting techniques, many global brands have stepped forward and dished out their own sophisticated CAD drafting software – thus eventually making it difficult for customers to make up their mind which program to pick. In order to help you out with the cause, today we are going to have a closer look at 3 of the best CAD drafting software around in the market today:

      1. AutoCAD
      2. CATIA
      3. MicroStation

      What makes AutoCAD one of the best CAD drafting software

      AutoCAD made its way into the market as an excellent CAD Drawing Software almost 3 decades back – in 1982, and ever since has been there at the top continuously ruling the charts. It is undoubtedly the best utility for documenting your design ideas – and thank the wide range of features and tools it brings along, the whole drafting process becomes more like a walk in the park. The program allows efficient editing and repurposing the drafting process in order to iterate and evaluate the available design options. Allowing the improvisation of existing geometries with easy-to-remember and easy-to-execute commands is another highlighting feature of this program. Now, let’s have a look at the key advantages that make AutoCAD the best CAD drafting software in the market today:

      • It allows you to drive efficient design documentation and other important drafting practices.
      • Efficient reuse of content is possible.
      • You can work on either Windows or Mac platform – whichever you may prefer
      • It allows you to customize your work environment as you prefer

      How CATIA made it to the list of best CAD drafting software

      CATIA – which happens to be the abbreviation for Computer-Aided Three-dimensional Interactive Application, also deserves to be there in the list of the 3 best CAD drafting software around today. It is a multi-platform suite written on the C++ language. Even though the first stable release was on March 2011, the origin of CATIA can be traced back to as early as 1977.

      CATIA is a leading product development solution for manufacturing organizations across various industries, including aerospace, industrial machinery, electrical, automotive, electronics, plant design, shipbuilding and what not! Some of its highlighting aspects include:

      • Easy drafting even in the context of rather large products or configuration
      • Real-time drafting with adequate security, integrity as well as traceability
      • Support for multi-disciplinary collaboration on diverse systems and products
      • Cross-platform support

      Three decades of excellence makes MicroStation one of the best software

      Dished out by Bentley Systems, MicroStation is a computer-aided design software suite for both two as well as three-dimensional design and drafting purposes. This widely popular product across multiple industries has been around in the market since the 1980s. While earlier its focus was more at Apple’s Mac platform, the recent most releases of this CAD Drawing Software are exclusively aimed at the Windows OS. While DGN is its native format, MicroStation also extends its compatibility to other formats like DWG, DXF, AVI, JPEG, BMP, PDF, VRML and so on. As one of the best CAD drafting software, Microstation facilitates:

      • Extensive format inter-compatibility, including the likes of DGN, DXF, PDF, 3DS, IGES, IFC, CGM and what not
      • Real-time sharing of live design data across all project participants simultaneously
      • The ability to view and render point clouds with bare minimum effort.

      sketchup VS Autocad

      Can Google Sketchup replace AutoCAD?

      If you spend any time at all using designing tools or rendering and model software, whether professionally or as a hobby in your free time, you’ve no doubt heard of Google Sketchup by now.

      A fast, free, easy to learn designing tool that competes with AutoCAD (or does it?), Google Sketchup offers an extremely friendly user interface and a minimized look and feel that might, at first glance, seem to lack the horsepower of more well-known modeling software. However, like an old-school muscle car that’s been supercharged, the real power can only be seen when you pop the hood. But even though the user interface and capabilities of Sketchup might seem to be giving AutoCAD a run for its money, there are two large limitations that will need to be overcome before Sketchup can hope to take on the big dogs.

      Limitation: Compatibility

      Sketchup is still wrestling with a few debilitating bugs. At last check, textures imported into Maya 6.0 or 6.5 had a tendency to reverse themselves. Any mesh system being transferred out of Sketchup will need to be recreated on the receiving machine. And if you’re thinking about exporting to Vasari, forget about it – the list of bugs is too long to list here. These issues will need to be addressed and remedied before Sketchup can hope to gain any kind of serious market traction against AutoCAD.

      Limitation: Naming Conventions

      Perhaps more than any other limitation, the forced truncation of file names for Google Sketchup textures poses a problem for users commanding large, complex, or sophisticated projects that require specific naming conventions. Google Sketchup is limited by the antiquated 8.3 DOS character maximums, so file names have to be shortened to eight characters or less. This poses a significant problem for high-end designers juggling hundreds or thousands of textures that have to be swapped in and out quickly and easily, since naming conventions will be far less intuitive with Sketchup than they would be with AutoCAD – or just about any other form of computer aided design software.

      Advantage: Free Models

      Google Sketchup hooks up to 3D Warehouse, which contains a seriously massive assortment or pre-designed models of all shapes and sizes. Hundreds of thousands of them. While AutoCAD typically ships with around 4,000 pre designed model templates – and users can easily access a few thousand more on one of the many AutoCAD user sites out there – the availability of pre-designed models from Sketchup is absolutely jaw dropping.

      If and when Google manages to correct the compatibility and naming convention problems with Sketchup, AutoCAD will have a tough and determined competitor. Until then, serious designers are smart to stick with the big dogs.
