大神，有试出来吗？
通过咨询上面的大佬

内部图元改为黄色后，选择的时候用选择过滤器过滤黄色的图元，大概就差不多实现了这个效果，就是图元太多的时候效率稍慢一点 qq25469005 发表于 2023-2-27 14:53

试了一下，出现：错误: no function definition: CURVE，大神能搞个完整的出来吗？谢谢分享！ 本帖最后由 qq25469005 于 2023-2-28 13:30 编辑

这个要使用ifoxcad开发
/// <summary>
/// 改变被包围的图元颜色为黄色
/// </summary>
public void WaiKuang()
{
using DBTrans tr = new();
var ents = Env.Editor.SSGet().Value.GetEntities<Curve>().ToList();
//ents.ForEach(t=>t.ForWrite(e => e.CloseCurve(tr)));
for(var i = 0; i < ents.Count-1; i++)
{
for(var j = i+1;j<ents.Count;j++)
{
Q_EntityEx.IsPolygonInsideAnotherPolygon(ents, ents);
}
}
}
