The best way to Copy Point2dCollection.

[joantopo]

What is the fastest function to coy a Point2dCollection? -Loop with Foreach: foreach (Autodesk.AutoCAD.Geometry.Point2d pt in list) { NewList.Add(pt); } or: NewList(list.CopyTo(array[],0));

I don't know why there isn't a Point2d.CopyTo method, but there is a Point3d.CopyTo. Have you tried it out?

Which is your release? In Civil 3D 2014 I have both.

Interesting! I'm referencing the ObjectARX for vanilla AutoCAD 2011.

So do you think the .CopyTo method will do the trick for you?

It works: Point2d[] array = new Point2d[Coll1.Count]; Coll1.CopyTo(array, 0); Point2dCollection newColl= new Point2dCollection(); newColl.AddRange(array); "CopyTo() is void, not a function and doesn´t return a collection.
