Computer-aided design (CAD), also known as computer-aided design and drafting (CADD) is the use of computer technology for the process of design and design-documentation.

So, every program which was designed to help the user in the process of design can be called a CAD program.

Yo can call such program in any way you want, for example A Mickey Miki Mouse Cad Program. But is still A CAD. Even a small, primitive program for drawing and making circles on the screen is a CAD.

A program mentioned in may last post ( the one for the tunnel hull boats ) looks very inetresting.

Have good day, Basstronics.
