I have sent a purged drawing to a client and they are telling me that there are still items that need to be purged. However, when i try to purge my drawing it does not reveal any items that are able to be purged.
You could have nested blocks, sub-objects of blocks referencing layers, etc....
A couple of favorites:
- leaders in block definitions, preventing purging of dimension styles
- text settings in dimension styles, preventing purging of text styles
- blocks as arrow heads in dimension styles, preventing purging of text styles
- block definitions with non-BYLAYER/BYBLOCK objects, preventing purging of layers or line types
- materials associated with nested XREFs
- deeply nested block definitions created by data-only or invisible attribute -only blocks e.g. BLOCK A -> AF -> FLOW -> AFLOW
- blocks with only invisible attributes
They may be using "purge" as a generic term, where they mean remove e.g. excess annotation scales.
