CAD SOFTWARE

What is CAD software?

CAD, or computer-aided design and drafting (CADD), is the use of computer technology for design and design documentation. CAD software replaces manual drafting with an automated process.

If you work in the architecture, MEP, or structural engineering fields, you’ve probably used 2D or 3D CAD programs. These programs can help you explore design ideas, visualize concepts through photorealistic renderings, and simulate how a design will perform in the real world. AutoCAD software was the first CAD program, and it is still the most widely used CAD application.

CAD software features

CAD programs have different features depending on whether your design process involves 2D vector-based graphics or 3D modeling of solid surfaces. Most 3D CAD programs let you apply multiple light sources, rotate objects in three dimensions, and render designs from any angle.

Autodesk’s CAD programs

Our customers use Autodesk CAD software to design cars, ships, bicycles, prosthetics, and much more. Our CAD programs are available for Windows; many are also available in Mac-compatible formats. CAD software is also included in Autodesk product suites for building design, product design, factory design, and more.
