so last guess before I try to simulate your situation
You exploded the DWG1, so you have in this drawing
Now you check "how often is my BlockTableRecord named "BLOCK1 referenced within that database".
Look to the colored words ==> 2
- alfred -
I understand now. thanks
When you explode Dwg1, you're making a copy of the block reference in Dwg1,
so you end up with two block references:
one in the Dwg1 block table record, and one in the *Model_Space block table record.
