我试试，认真学习下dcl。回报mj。
两个半天一个晚上的学习，汇报结果。
程序不完整，一上手就是动态，对初学者有点难度，而且没有做出效果。
先给你一个对话框驱动的通用函数
(defun dlg_load (dlgfile tag initialize dlg_action / DLG_ID)
(if (> (setq DLG_ID (load_dialog (findfile (strcat dlgfile ".DCL")))) 0)
(progn
(if (new_dialog tag DLG_ID)
(progn
(initialize)
(dlg_action)
(setq result (start_dialog))
)
(princ "\nCan't display dialog")
)
(unload_dialog DLG_ID)
)
(princ "\nCan't open dialog")
)
)
初始化参数及控件函数
(defun bearing_ini ()
;(setq
;(set_tile
;(mode_tile
;;;
)
控件驱动函数
(defun bearing_act ()
;(action_tile
(action_tile "accept" "(done_dialog 1)")
(action_tile "cancel" "(done_dialog 0)")
)
调用通用对话框函数
(dlg_load bearing BEARING bearing_ini bearing_act)
(if (= result 1)
(draw_bearing);;;画轴承
(princ "Bearing function cancelled!\n")
)

我这里有一个轴承的数据库忘记在哪里弄的了挺全的
本人一直想做一个可是一看轴承的种类就晕了
常用的还用作用lisp程序吗 事先画好了做成块用的时候一粘贴多省事
