CAD System Design on Standard Part Based on Software Reuse

In the field of CAD, the software system is of varies category and large amount and the problem of repeated development is existed in considerable amounts. For this reason, it is greatly meaningful to use the thought and technology of software reuse to develop products. The paper states the current situation and development of the CAD technology, analyses the technical mechanism and key techniques of secondary development based on Solid Works platform and specifies the process of secondary development of three-dimensional CAD software, Solid Works, by thought of software reuse through some cases.
