Clean Up Internal Blocks (Library Menu)

This command clears up the internal blocks in the current drawing. This means that all internal blocks which are currently defined but not in use are deleted.

Before this command is carried out, you are asked for confirmation, to avoid the accidental deletion of internal blocks.

Internal Blocks deleted with this command can not be recovered using Undo. If internal blocks are accidentally removed they can usually be restored from the last saved version of the drawing using the command Import > Malz++Kassner CAD6 (*.MKD).
