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.
TECHNICAL DRAWING
Draft precise and detailed drawings quickly with CAD software from Autodesk.
What is a technical drawing?
Why are technical drawings important?
Technical drawings bridge the communication between designers, the people who come up 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 (US site) are detailed, precise depictions of every aspect of the construction being proposed. Architects use the drawings to visualize ideas and concepts, turn a design idea into a coherent plan for a building, and decide the type of supplies and labor that is needed for the project.

Delivering the world's fastest electric motorcycle
Electric motorcycle builders out-raced the gasoline-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 achieve world records.
Creating a "ropeless" elevator for the U.S. navy
Federal Equipment Company designs highly innovative elevators for the U.S. Navy with help from Autodesk software, including AutoCAD, Revit, Inventor. Collectively, these programs helped performed initial finite element analysis (FEA), track materials, and optimize designs for manufacturability, ultimately, reducing cost overruns associated with production stoppages and rework.
