关于画双线每个线指定图层问题
本帖最后由 403181713 于 2019-11-24 19:21 编辑前两天借用了论坛上的一段代码画双线，忘了哪位朋友写的了，现在我想画过双线后，每一根线可以指定图层。恳请高手指点！代码如下：
(defun c:2L()
(if (= wwdy nil) (setq wwdy 4))
(setq str1 (rtos wwdy 2 2))
(prompt "\nnow dline width is: ")
(prompt str1)
(setq pt1 (getpoint "\n enter start point:"))
(setq pt2 (getpoint pt1 "\n enter next point:"))
(setq dis1 (* 0.5 wwdy))
(setq ag1 (angle pt1 pt2))
(setq pt1u (polar pt1 (+ ag1 1.5708) dis1))
(setq pt2u (polar pt2 (+ ag1 1.5708) dis1))
(setq pt1d (polar pt1 (- ag1 1.5708) dis1))
(setq pt2d (polar pt2 (- ag1 1.5708) dis1))
(command "pline" "non" pt1u "non" pt2u "")
(command "pline" "non" pt1d "non" pt2d "")
(repeat 100
(setq pt1 pt2)
(setq pt2 (getpoint pt1 "\n enter next point:"))
(setq dis1 (* 0.5 wwdy))
(setq ag1 (angle pt1 pt2))
(setq pt1u (polar pt1 (+ ag1 1.5708) dis1))
(setq pt2u (polar pt2 (+ ag1 1.5708) dis1))
(setq pt1d (polar pt1 (- ag1 1.5708) dis1))
(setq pt2d (polar pt2 (- ag1 1.5708) dis1))
(command "pline" "non" pt1u "non" pt2u "")
(command "pline" "non" pt1d "non" pt2d "")
)
)
初入LISP小白，熬了一星期夜解决不了！有劳大佬了，跪谢！
