Purpose: Remove CLEANUP elements inside blocks
This tool cleans the inside of blocks without affecting the rest of the drawing. It opens the DWG, goes through each block in the drawing, looks inside for entities marked “CLEANUP” / “MASK”, deletes them, and then saves the DWG. No other geometry or property is modified.

The software opens the DWG to be cleaned.
Loading the source file. Access blocks one by one
