基于OpenCASCADE的轴三维参数化设计系统

Design of Parametric System of Shaft Based on Open CASCADE Modeling

将OpenCASCADE与VC++结合,开发了轴的三维参数化造型与标注。根据轴的关键尺寸确定造型参数,利用OpenCASCADE相关建模函数和可视化功能建立轴的三维几何形状并显示和标注,再结合VC++来完成参数化人机交互界面。设计人员只需输入轴的关键尺寸,就可以快速实现各种轴的三维设计几何模型,为编制自主版权的参数化造型系统提供一个可行的思路。

This article uses OpenCASCADE with VC ++ to develop a three-dimensional modeling and mark of the shaft. The modeling parameters are determined according to the key dimensions of the shaft, the 3D geometry of the shaft is established and displayed by using the modeling functions and visualization functions related to OpenCASCADE and it is used with VC++ to finish the parametric human-computer interaction interface. Only the key dimension of the shaft is entered, the geometic model of three-dimensional design can be obtained quickly. The feasible idea is provided for independently compiling the parameterized modeling system.
