CAD (Computer Aided Design or Computer Aided Drafting) is application for2D and 3D

design and drafting,CAD programs to run on personal computers, in earlier releases.

CAD used primitive entities such as lines, poly lines, circles, arcs, and text, as the foundation for

more complex objects. Since the mid-1990s, CAD has supported custom objects through

its includes a full set of basic Solid modeling and 3D tools.

CAD is used in the design of tools and machinery and in the drafting and design of all types of

buildings, from small residential types to the largest commercial and industrial structures.
