Most CAD software at the time ran on graphics terminals connected to mainframe computers or mini-computers. In earlier releases, AutoCAD used primitive entities such as lines, polylines, circles, arcs, and text — as the foundation for more complex objects. Since the mid-1990s, AutoCAD has supported custom objects through its C++ API. Modern AutoCAD includes a full set of basic solid modeling and 3D tools.
