What is a technical drawing?
A technical drawing, also known as an engineering drawing, is a detailed, precise diagram or plan that conveys information about how an object functions or is constructed. Engineers, electricians and contractors all use these drawings as guides when constructing or repairing objects and buildings.
Why are technical drawings important?
Technical drawings bridge the communication between designers, the people who come up with ideas, and producers, the people who put those ideas into practice. They’re designed as a universal language to be understood by engineers, contractors and architects.

Types of technical drawings
Mechanical engineering drawing
Mechanical engineering drawings are used to define the requirements for engineering products/components. They serve as technical manuals and as trouble-shooting tools for identifying the weak spots in a mechanical design. Mechanical drawings rely on precise mathematical equations to accurately depict the mechanism and it component parts.
Electrical drawing
Electrical drawings (US site) are technical documents that depict and notate designs for electrical systems. They convey relevant information about lighting, wiring and power sources, as well as information about voltage and capacity. Technicians rely on electrical drawings during a building’s construction or when repairing a building’s electrical system.
Architectural drawing
Architectural drawings are detailed, precise depictions of every aspect of the construction being proposed. Architects use the drawings to visualise ideas and concepts, turn a design idea into a coherent plan for a building and decide the type of supplies and labour that is needed for the project.

Delivering the world's fastest electric motorcycle
Electric motorcycle builders out-raced the petrol-powered competition with a superbike developed with generative design and 3D printed prototypes. Autodesk’s iterative process to auto-design translated into significant gains in speed and range for the motorcycle, helping them to achieve world records.
Creating a "ropeless" lift for the US navy
Federal Equipment Company designs highly innovative lifts for the US Navy with help from Autodesk software, including AutoCAD, Revit, Inventor. Collectively, these programmes helped performed initial finite element analysis (FEA), track materials and optimise designs for manufacturability, ultimately reducing cost overruns associated with production stoppages and re-work.
