复制最近的高程
是否有lisp例程使其更容易？因为我是手工做的，太耗时了。。有没有办法复制最近多段线的高程，并使其成为其他对象的高程，而不包含其高程或Z？？？
图纸2.dwg 我做了一个！嗯，至少我可以更快地工作。。。
如果有人能做得更好，我真的很乐意接受建议

(defun c:qq (/ elevations sss)
(if (ssget '((0 . "*POLYLINE")))
(progn
(vlax-for x (vla-get-activeselectionset

)
(setq elevations (cons (vla-get-elevation x) elevations))

(prompt "\n2nd Selection")
(setq sss (ssget "_:L"))
(command"_.CHANGE" sss "" "_P" "_E" (rtos (last elevations))
)
)
)
(princ)
) 考虑以下因素：
(defun c:fixelevation ( / dis dst elv ent enx idx lst src tmp vts )
(if (and (setq src (LM:ssget "\nSelect polylines with elevation: " '(((0 . "LWPOLYLINE")))))
(setq dst (LM:ssget "\nSelect polylines to modify: " '("_:L" ((0 . "LWPOLYLINE")))))
)
(progn
(repeat (setq idx (sslength src))
(setq ent (ssname src (setq idx (1- idx)))
lst (cons (cons ent (assoc 38 (entget ent))) lst)
)
)
(repeat (setq idx (sslength dst))
(setq enx (entget (ssname dst (setq idx (1- idx))))
vts (mapcar 'cdr (vl-remove-if-not '(lambda ( x ) (= 10 (car x))) enx))

命令：fixelevation
选择具有高程的多段线：
选择要修改的多段线：；错误：没有函数定义：
VLAX-CURVE-GETCLOSESTPOINTTO
有一个错误，先生，我想更改的不是突出的多段线，而是文字（位置Z）、引线（顶点Z）、直线（星形/端点Z）。。。 请尝试上面更新的代码。
