基于AutoCAD VBA的螺旋面零件参数化造型技术

The Technology of Sculpting a Part with Helix Property by Parameter Based on AutoCAD VBA

参数化设计在机械产品设计中非常适用,是农业机械工程人员实现快速造型的关键技术之一。本文通过实例阐述了如何通过AutoCAD二次开发出螺旋面零件三维模型的VBA程序,实现螺旋类零件的参数化造型,提高农业机械产品设计的效率,加快了产品开发周期。

Parameter design is very useful in machine product design; it is the key technology in realizing speediness sculpting for agro-machinery engineering personnel. This paper expounds how to develop helix parts 3D model VBA program by AutoCAD secondary development, which can realize parameter sculpting for helix parts, enhance design efficiency, quicken products development period.
