Hi, I am writing a small program to take in AutoCAD entities that have been copied/cut and pasted into the modelspace. The problem that I am having is that when I paste a Line, I get three ObjectAdded events. They are in the following order: Line Added, BlockReference Added and Line Added. After I have clicked on the drawing to paste the Line, the BlockReference gets erased but the first line does not. Is there anyway for me to find out of the Objects that were added to the drawing and are still in the drawing? Thanks, Jaspreet
