Question
A
Some add-on applications may create a large number of anonymous groups in a DWG file while copying objects. These anonymous groups (blocks) are named like *A1, *A2, .... *A####. They cannot be erased with standard AutoCAD tools.
To delete and remove these groups, use the freeware utility by CAD Studio - DelGrpA. Download the LSP file from Download, load it with APPLOAD and run the DELGRPA command. This command lists all deleted anonymous groups.
