I have a dwg with a linetype that I can't get rid of. All entities in the dwg are set to linetype ByLayer, I ran SetByLayer with included blocks and no layer is using this linetype. I can't purge this linetype.
When I run vla-delete on the vla-get-all-linetypes collection, it errors out with "error: Automation Error. Object is referenced by other object(s)"
If anybody has any idea what could be referencing this linetype, I would greatly appreciate it.
