基于CATIA软件对VBA的支持进行曲面设计

Using VBA to Design Curved Surface Based on CATIA Software

介绍了根据CATIA软件对VBA(Visual Basic for Application)的支持,利用VBscript脚本语言,开发复杂曲面的造型设计程序的方法。利用数学方法计算生成其截面控制点,利用程序读取控制点坐标,直接在CATIA软件曲面设计环境中,自动生成各剖面的Spline曲线,然后采用CATIA高级曲面的"Loft"命令完成复杂曲面的造型设计。

A method used to design Curved surface by means of program is introduced in this paper. The program is developed by VBA on the base of CATIA software. For a baffle with complex profile, the control points of section are calculated by a mathematical function. The splines of former sections are created automatically in the Generative Shape Design of CATIA using VBA program which read direct a series of coordinates of control points, finally, Curved surface shape is generated by ＂Loft＂ command of CATIA.
