初学ug二次开发的GRIP语言,想用GRIP语言画个渐开线花键,但是关于曲线剪切命令不会使用,总算让我试出来了,先来个小例子讲解一下吧!我要将ln3用c2和ln1裁剪,
& a3 H9 U/ K" x$ l( m. C) ^grip语言剪切命令CRVTRM命令格式:' S e8 e: `+ L2 @: c; ~
Obj=CRVTRM/curve,REF,{pt1|x,y,z},$
# V) z0 O& f1 a) xFIRST,limit1[,REF,{pt1|x,y,z}]$
6 Y3 {* L! @% ~, I) X: Y2 i8 d[,INT,{pt2|x,y,z}][,NOTRIM]$
7 B; R, s/ y: N9 V1 Q[,SECOND,limit2[,REF,{pt1|x,y,z}]][,INT,{pt2|x,y,z}][,NOTRIM]]$
0 G" p* y+ d/ p! G0 V$ p,STATUS,status[,IFERR,label:]$ T6 j( ?* C7 C. x$ t- [
. m) h% g8 w2 d; ^. \ ]
具体实现代码如下,直接可以放到grs中运行!
