Wondering if anyone knows a way to do a data extraction but have it not count overlapping blocks.  
Example would be 2 sections of fence but each section is a dynamic block each with a post on both ends.  So when you put them together it should be 3 posts but counts 4 since there are 2 in the middle.  Is there a way to only count that as 1?

Appreciate the help

Hello, i would compose the blocks, that would have this problem, into two blocks; one is the fence and the other would be the post. after the drawing is finisched, you explode the combined blocks. after exploding, a simple vba routine can detect if similar blocks have the same insertion points. the vba code can deletes these double insertions. and then you have a correct count
