1.04892e-006)) 如何才能让已有的SPLINE提供11组码？

无痕

不行了。改了阶数，万劫不复

BDYCAD

SPLINE曲線, 如果是剛畫出來再用ENTGET涵數可以查到11的組碼. 但是如這樣SPLINE曲線經過打斷, 或都修剪和偏移后. 11的組碼就不見了. 我也不知是什麼回事.

龙龙仔

dxf 10的组码不好用嗎?

BDYCAD

可用. 但是因為缺少11的組碼時. 下面這個貼子的程序就不太完善哦. http://bbs.mjtd.com/forum.php?mod=viewthread&tid=13129

在无痕的帮助下，已经找到了原因：只有三阶SPLINE有拟合点。

BDYCAD

樓上, 請教何為三阶SPLINE呀? 沒有聽說過哦.
