I need to manage the import of DXF files into our plan management system. However, it often happens that objects are outside the scope of the MEP (these objects are not useful for us). I'm trying to create a macro that would erase all the entities that are out of frame. I manage to select all the entities of the MEP (1st selection set) as well as all the entities within the framework of the MEP (2nd selection set). But I can't select all the entities EXCEPT the ones in the frame: basically do Game1 - Game2.
Someone would know the method to achieve this. Thank you in advance.
