完全可以实现,可将详图发至ljttjl@ tom.com
楼上的搂了多少业务啊，说来听听

(defun c:tt(/ ss sum i ena sum)
(vl-load-com)
(setq ss (ssget '((0 . "*line"))))
(setq sum 0 i -1)
(repeat (sslength ss)
(setq i (+ i 1))
(setq val (vlax-ename->vla-object (ssname ss i))
eparam (vlax-curve-getendparam val )
)
(setq sum (+ (vlax-curve-getdistatparam val eparam ) sum))
)
(setvar "dimzin" 8)
(princ (strcat "总周长长度是" (rtos sum 2 3)))
(princ)
)
