标题: VBA怎样删除重复的圆？ [打印本页] 作者: taqqug 时间: 2010-1-23 17:30 标题: VBA怎样删除重复的圆？ 弱弱的问一下大家，CAD中怎样用VBA标记出有重复的圆，并提示删掉？我现在用选择集选择了所有的圆，想用圆心相等来判断（还得半径相等），可是圆心不让比较，请大家帮忙，最好给出代码，谢谢啦！！作者: sealive_leafage 时间: 2010-1-23 21:19 本帖最后由 sealive_leafage 于 2010-1-23 21:21 编辑 ! @5 ]# Q+ I1 W' H$ w2 j0 w4 B" V!

圆心(点)是数组,得分别比较三个坐标才行.
