摘要
为有效发挥CATIA软件在有严格约束复杂曲面造型方面的计算快速、曲线精度高的优势,开发了基于宏命令的样条曲线自动生成程序,通过读入点坐标,利用程序生成CATIA的宏命令,然后利用CATIA软件在"创成式外形设计"环境下读入并运行宏命令,直接生成样条曲线。结果表明,此方法在处理由大量数据构成的曲面引导线时,可以有效提高工作效率并极大地降低数据出错的可能性。
To take advantage of high-fidelity, fast generation capability of CATIA software in generating curved surfaces, an auto-generation program of splines was developed based on macro command. The coordinates of discrete points are read in and then converted to CATScript. Then the macro script is read by CATIA in the ＂generative shape design＂ mod- ule, and the spline is generated. To employ this tool to deal with the guide curves of sur- face from massive data can increase the work efficiency and greatly decrease the data er- ror.
