(求助)请教一下各位大神，能不能帮忙解决关于批量修剪的问题
本帖最后由 999999 于 2020-12-21 10:40 编辑麻烦路过的大神，有没有知道解决这个问题的，
1.输入命令
2.框选修剪对象(框为:矩形，圆形，椭圆)
3.修剪多个框外的对象（框外对象为:多断线，直线，辅助线，圆弧）
以下是CAD2007里面超级修剪的源码，请教各位大神，能不能帮忙改成可以批量框选的

支持，顶一下 需要多次裁剪，每次裁剪后，剩余部分的图元名可能发生变化，要点就是重新获取剩余图元选择集进行操作 satan421 发表于 2020-12-21 09:37

我一开始以为就是把选择的方式改一下就可以哟 本帖最后由 lee50310 于 2021-1-8 14:37 编辑
下方這個圖不能用裁剪 ,要用交點打斷原因是你要在交點處裁剪這些不要的線段 光選點就是一大難題但是如果你用物件交點打斷,然後在圈選你要的物體,並去除不要的線段就可完成
