3D CAD, or three-dimensional computer-aided design, is technology for design and technical documentation, which replaces manual drafting with an automatedprocess. Used by architects, engineers, and other professionals, 3D CAD softwareprecisely represents and visualizes objects using a collection of points in three dimensions on the computer.

Autodesk has a broad portfolio of 3D CAD software programs to help people explore and share ideas, visualize concepts, and simulate how designs will perform before they are made.
