在很多年之前就编过，可以同时给不同的对象进行中心线标注，包括圆、圆弧、矩形等，

谢了先，这个不好用，有没有象LTOOLS里CL一样的,可以对圆、圆弧、矩形画中心线，中心线长度可以自动调整
楼上的兄弟，可不可以分享一下，谢谢先

谢了先，但功能不好，对2条直线不能画中心线，中心线长度都是固定多出2MM，不能按比例调整
LTOOLS里的CL就可以，不知道哪位有这个LISP，谢谢先

作者: clswww 时间: 2006-11-6 22:33
终于找到个好的，中心线自动比原来多10％，自动放在CEN层

怎么没有附件？~~ 要不你加我QQ

怎样用啊？

作者: liu-jinpeng 时间: 2010-10-20 17:13
谢谢啦!!!!!!!!!!!

还是不懂！！！！

回8楼的

你的这一段有问题

   (command "line" (list (+ (* 1.05 cl_rad) (car cl_pt)) (cadr cl_pt))
                  (list (- (car cl_pt) (* 1.1 cl_rad)) (cadr cl_pt)) "")

   (command "line" (list (car cl_pt) (+ (* 1.1 cl_rad) (cadr cl_pt)))
                  (list (car cl_pt) (- (cadr cl_pt) (* 1.05 cl_rad))) "")

画圆的中心线时一边长处1.05 另一边长处1.1
