多线图层不能指定，请前辈指点指点

fedd

请前辈指点，为什么折断线指定图层就不行呢？如果把2细线层值这一句代码删除就没问题，加上就不行，为什么呢？
(defun c:77 (/ pt1 pt2 pt3 pt4 pt5 pt6 ang dis old1)
(setq old1 (getvar "blipmode"))
(setvar "blipmode" 0)
(setvar "clayer" "2细线层")
(setvar "OSMODE" 16383)
(setq pt1 (getpoint "\nSelect the first point:"))
(setq pt2 (getpoint pt1 "\nSelect the second point:"))

(setq dis (distance pt1 pt2))
(setq ang (angle pt1 pt2))
(setq pt1 (polar pt1 (+ pi ang) (* dis 0.15)))
(setq pt2 (polar pt2 ang (* dis 0.15)))
(setq pt3 (polar pt1 ang (* dis 0.6)))
(setq pt4 (polar pt3 (- ang (* (/ 80.0 180.0) pi)) (* dis 0.15)))
(setq pt5 (polar pt4 (+ ang (* (/ 80.0 180.0) pi)) (* dis 0.3)))
(setq pt6 (polar pt5 (- ang (* (/ 80.0 180.0) pi)) (* dis 0.15)))
(setvar "osmode" 0)
(command "_Pline" pt1 "W" 0 0 pt3 pt4 pt5 pt6 pt2 "")
(setvar "osmode" 255)
(setvar "blipmode" old1)
)        ；；end defun

可能是本图没有这个图层

(setvar "clayer" "2细线层")  ;這個是設定 2细线层 為當前圖層，如果圖檔本身沒有就沒辦法用

有这个图层，而且我换另一个图层还是不行

masterlong

这种情况下

正常运行  可以指定

谢谢各位大侠，代码没问题，估计软件有问题
