Sometimes the block with definition may not be used in our drawing, to reduce the size of drawing, it needs us to confirm if these kinds of block definition is non-used then delete them.
We could use “purge” command to recognize and delete them. If we create large quantity of block definitions which are non-used then we could use “purge” to delete them and reduce the size of drawings.
