What is 3D CAD software?
3D CAD, or 3-dimensional computer-aided design, is technology for design and technical documentation, which replaces manual drafting with an automated process. Used by architects, engineers, and other professionals, 3D CAD provides an extra dimension to precisely visualize and share designs.
Autodesk has a broad portfolio of 3D CAD software programs to help people explore ideas, visualize concepts, and simulate how designs will perform before they are made.
