一个关于自动标注倒角的程序思路
本帖最后由 mj520plus 于 2012-12-27 23:33 编辑想编写一个自动标注倒角的程序，类似于PressCAD的CMN命令。
功能：鼠标点选倒角线或多义线，自动标注倒角大小，如下图：
思路：求出鼠标点选处端点P1和P2的坐标，算出倒角的大小。
难点：通过什么函数来求解鼠标点选处端点P1和P2的坐标?
请各位大虾指点，谢谢！
模板上倒角框很多个不是吗?
我们的作法是让程序自个儿去我且完成标注...
(一个思路,谨供参考) 回复的人这么少，是不是我提出的问题太简单了，不屑回答啊！
大家有没有现成的程序奉献出来，在此先谢谢了！
想法很不错 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

像用距形命令画出的长方形倒角，即多段线命令绘出的倒角标注不了，必须打散，另外倒角尺寸放置不美观，没有达到楼主那样引线标注
