Remove Block Definitions
To reduce the size of a drawing, you can remove unused block definitions.
You can remove a block reference from your drawing by erasing it; however,
the block definition remains in the drawing's block definition table.
To remove unused block definitions and decrease the drawing size, use PURGE
at any time in your drawing session.
All references to a block must be erased before you can purge the block
definition.
