Computer-aided design (CAD) software is used in various industries to create 2D technical drawings, mock-ups of conceptual designs, and 3D models of physical objects. These digital representations of physical objects are used in the creation of actual objects in the tangible world. The products in the General-Purpose category include CAD programs that offer a wide range of tools and functionality to their users. While products may vary in their strengths and the breadth of their capabilities, they are not designed exclusively to meet the needs of an individual industry or field. Furthermore, products in this category have the potential to integrate with more specialized tools such as those in the Civil Engineering and BIM software.
