[求助]求助caoyin 版主，如何获取QLEADER末端的那个端点的坐标？

userzhl

(setq ssi (ssget))
(if ssi
(if (= (cdr (assoc 2 (setq edat (entget (setq e (ssname ssi n_in)))))) "材料")
(progn
(setq n_in 0)
(setq len_in (sslength ssi))
(command "undo" "begin")
(repeat len_in
    (setq INS (cdr (assoc 10 edat))
 INSc (cdr (assoc 41 edat)))
 (command "_SCALE" e "" INS (/ scal (abs INSc))))
)
(setq n_in (+ 1 n_in))
)
(command "undo" "end")
)

为何会出错呢？

选择对象: 指定对角点: 找到 8 个
选择对象:  ; 错误: 参数类型错误: numberp: nil

    (progn
      (setq INS  (cdr (assoc 10 edat))
            INSc (cdr (assoc 41 edat)))

;;我改了一下，但你未指定 scal 变量
