Electrical Schematic & Line Diagram Drafting
Industry : Heavy Engineering Company Location : Australia
Technology & software used
- Electrical drawings are crucial to convey the information about how the electrical components are connected together to serve specified electrical functions. A well-defined wiring diagram considerably reduces the wiring efforts and minimizes the possibilities of errors during the actual installation. Australian Design and Drafting Services provided CAD solutions to a leading PLC manufacturer from by providing detailed wiring diagrams, schematic layouts and line diagrams based on inputs received.
The solution we delivered
- We utilized AutoCAD to convert hand drawn sketches into detailed wiring diagrams, schematic layouts and line diagrams as required by the client. Ensuring the standard conventions for electrical symbols, the 2D drawings were checked for any missing information to avoid any possible errors during installation. The conversion process was accomplished within specified time frame and the output files were provided as per the format requested by the client.
Outcome & benefits
- Minimized errors that may encounter during installation.
- Completed Missing information in the layouts and wiring diagrams.
- Reduced wiring efforts during installation due to comprehensive wiring diagrams.
- Australian Design and Drafting Services is a specialist firm providing engineering solutions to organizations across the globe. We have extensive experience in providing concept to manufacturing and post-manufacturing solutions to clients with a team of expert design engineers, CAD professionals and simulation analysts. We are based in Australia, serving 24×6, with a world-class infrastructure, hardware and software capabilities to address complex engineering problems with least turn around time.

Our electrical schematic drafting service
Electrical schematic drafting is detail work where consistency is the whole job: device designations that follow one convention across hundreds of sheets, cross-references that actually resolve, and symbology to the Australian standards the reviewing engineer expects. We produce and redraw schematics and single line diagrams from whatever source exists — consultant markups, faded legacy drawings, site investigation notes — in AutoCAD Electrical or plain AutoCAD to suit the client’s environment, with title blocks and numbering matched to the destination drawing system.
Typical schematic projects
The work splits into three recurring shapes: new design documentation drafted from an engineer’s markups and calculations, legacy drawing modernisation where decades of paper amendments get consolidated into clean CAD, and as-built capture where the drawings must be made to match an installation that evolved undocumented. Each has its own QA emphasis, and we state which checks were performed so the drawings carry their own evidence.
Electrical engineers, contractors and facility owners send us schematic work when their own drafting queue is full or absent. Per-sheet and per-package pricing is available, and pilot sheets are standard practice so drawing conventions are agreed before the volume flows.
Volume schematic work also benefits from automation we have built over years of it: block libraries, attribute extraction for device schedules, and batch title-block updates that keep hundred-sheet packages consistent without hundred-sheet manual effort. That tooling is why our per-sheet pricing on large packages surprises clients used to paying manual-drafting rates for what is substantially mechanical work.
A final word on standards: schematics destined for Australian switchboards and installations follow AS/NZS 3000-aligned conventions and the client’s state-specific requirements, while export-bound documentation follows IEC symbology on request. We confirm the convention at pilot-sheet stage so the volume never needs rework.
