Being the first CAD programs to be executed on personal computers AutoCAD did capture the major market of industrial designers. It was initially derived from a proprietary language called Interact.
Initially when the software was released it had primitive entities as basic shapes and text to construct complex objects which later came to support custom objects through C++ interfacing. The latest version includes complete set tools to design and model, automation and customization.
