Modern AutoCAD includes a full set of basic solid modeling and 3D tools. Since the mid-1990s, AutoCAD has supported custom objects through its C++ API.
In earlier releases, AutoCAD used primitive entities - such as lines, polylines, circles, arcs, and text - as the foundation for more complex objects. Most CAD software at the time ran on graphics terminals connected to mainframe computers or mini-computers. inc Initially released in late 1982, AutoCAD was one of the first CAD programs to run on personal computers, and notably the IBM PC. AutoCAD is a CAD(Computer Aided Design or Computer Aided Drafting) software application for 2D and 3D Designing and Drafting, developed and sold by Autodesk.
