Current trends in the development of integrated general purpose CAD systems

摘要

This paper is approaching the computer aided design problem only from the programming point of view. Let us begin with two remarks to explain this approach:

rn

[i] very often computer aided design is heavily technology oriented; we mean that very often in a design process, the computer is used for the only phase of technological design of the object.

rn

[ii] moreover, until quite recently, CAD was considered only through application areas as, for example: aeronautics, electronics (circuits analysis), layout of printed circuits, civil engineering, ship building, etc...
