Abstract: The importance and development situations of the customized development platform of 3D digital design software are discussed. The key techniques of CAXASolid API including objects diagrams, naming convention, callback functions, App wizard and extension data object are researched. A complex application of CAXASolid API is also given, which is the 3D modeling of the bevel spiral gear based on the manufacturing process.

Key words: 3D digital design, Customized development platform, COM, Bevel spiral gear

摘要： 二次开发平台是三维数字化设计软件的重要组成部分，该文介绍了三维数字化设计软件二次开发平台技术的发展状况，研究了国产三维数字化设计软件“CAXA实体设计”二次开发平台的关键技术，给出了一个在CAXA实体设计上所做的复杂二次开发实例：基于加工过程的弧齿锥齿轮三维数字化造型。
