不知道是不是如图所示:
(defun c:tt()
(prompt "\n请选择两条直线:")
(setq ss (ssget))
(if (>= (sslength ss) 2)
(progn
(setq ent1 (entget (ssname ss 0)))
(setq ent2 (entget (ssname ss 1)))
(setq pt11 (cdr (assoc 10 ent1)))
(setq pt12 (cdr (assoc 11 ent1)))
(setq pt21 (cdr (assoc 10 ent2)))
(setq pt22 (cdr (assoc 11 ent2)))
(setq pt13 (mapcar '(lambda(x y)(/ (+ x y) 2.0)) pt11 pt12));中点
(setq pt23 (mapcar '(lambda(x y)(/ (+ x y) 2.0)) pt21 pt22));中点
(command "line" pt13 pt23 "");中点连线
(setq pt33 (mapcar '(lambda(x y)(/ (+ x y) 2.0)) pt13 pt23));中点连线的中点
(setq ang1 (angle pt13 pt23));中点连线的角度
(setq L (/ (distance pt13 pt23) 2.0))

)

可能我表述不清楚，图片现在应该清晰些
感觉坑有点深！

还好吧:lol，只是想点两个点生成一个十字线

非常感谢百忙中帮我些的程序:handshake，现在这个程序功能是只能选直线，能否改成用鼠标在两条直线上分别点一下，生成十字线，因为这两个直线有可能是多段线或者面域上的线条

:handshake可以用耶，就是鼠标点的多了点:lol

大佬请收下我的膝盖，此程序正是想要的:handshake，非常感谢！
