Application of CAD Secondary Development Technology in the 3D Parametric Design of Mechanical Parts

摘要

This paper mainly studies the technology of computer aided design in mechanical design application. In the three-dimensional spring parametrization design as an example, introduced the use of AutoCAD embedded Visual LISP development tools for 3D parametric graphic design principles, processes and methods, introduction of computer aided design technology, reduces the design personnel repetitive drawing work, improve the efficiency of design.
