I have a site plan from another .dwg that I copied with base point and inserted into my .dwg as a block. To edit this block in my .dwg I Rt. Click-Edit Block in Place, then use the Refedit Toolbar to save my changes. It seems each time I edit the block the linework, circles, etc. are duplicated; resulting in several duplicate objects stacked on top of each other within my block. I exploded the block, used the drawing cleanup tool and it found 37,000+ duplicate objects to delete! This happened before in another .dwg. I am running AutoCAD Civil3D Land Desktop Companion 2009, I also have an EaglePoint plug-in that we use to download our data if that helps.
Any suggestions to remedy this problem would be greatly appreciated.
