摘　　要：目前,参数化建模技术已经成为三维CAD产品设计的主流,MDT作为目前运行于微机上的优秀三维机械CAD软件之一,是功能强大的参数化特征建模工具。本文以标准直齿圆柱齿轮的参数化建模为例,论述了采用MDT的二次开发技术及其本身的三维建模技术建立这类具有精确的曲线轮廓的零部件的三维实体模型,也为其它类似的零部件的三维建模提供了一种切实可行方法。The parameterization modeling is the main technique that used frequently for three-dimensional CAD applications.As one of excellent three-dimensional CAD software, MDT has powerful parameterization modeling tools.This paper takes standard straight-cut gear parameterization modeling for instance, introduces the method which is based on development of MDT technology and MDT three-dimensional modeling technology.This research provides three-dimensional entity modeling of parts with precise curve outline.And it demonstrates a practical method for similar situations as well.
