我想咨询您一个问题，我们这边搞坝身坝基处理，有很多直线，有没有一个程序一次性把单根直线的长度和总长度都统计出来的

我的要求是要把每根线的长度全部量测出来，最后可以直接导入EXCEL里边的那种，不知道可以实现，上面发的程序我看一下，好像不行呢，

最初由秋枫发布
[B][code](defun c:TEST (/ ssmap getarea getlen alist lenlist)
(defun getarea (e)
(if (vlax-property-available-p (vlax-ename->vla-object e) "area")
(vla-get-area (vlax-ename->vla-object e))... [/B]

对region，长度返回0。用个原始的：

(defun getlen (sname / l)
  (command "._area" "_o" sname)
  (setq l (getvar "perimeter"))
)
(defun getarea (sname / ar)
  (command "._area" "_o" sname)
  (setq ar (getvar "area"))
)

eachy · 发表于 2008-12-24 09:48:52

用 vlax-curve-getarea 和 vlax-curve-getdistatparam

taner · 发表于 2008-12-24 10:03:51

最初由 eachy 发布
[B]用 vlax-curve-getarea 和 vlax-curve-getdistatparam [/B]

vlax-curve-getdistatparam 对REGION应该也是无效的。

非常感谢各位的支持与捧场，特别感谢7楼的朋友，感觉可以了，谢谢

carrot1983 · 发表于 2008-12-24 10:34:39

(defun getlen (sname / l)
(command "._area" "_o" sname)
(setq l (getvar "perimeter"))
)
(defun getarea (sname / ar)
(command "._area" "_o" sname)
(setq ar (getvar "area"))
)

最早学习的时候就用这个。。。
绕了那么大的圈，还是回到了原来的地方
呵呵。。。发现自已没长进啊。。。
