Development of Computer-Aided Design Module for Mechanical Products Based on AutoCAD

Abstract

Based on the basic process of mechanical product design and a modular design idea, the module includes three parts, i.e. design calculation, computer-aided drawing and foundation database. The design calculation mainly includes the commonly used design calculation program in mechanical product design, and the computer-aided drawing mainly includes the parametric drawing programs about the drawing environment and the commonly used machine parts, the foundation database mainly stores the data related to the mechanical product design. Then a computer-aided design module for mechanical product will be constructed by Autolisp and DCL. And the proposed computer-aided design module is developed on the friendly interface, easy to use, and can provide mechanical engineers for product design efficiency greatly.
