Purge Unused Arrowhead Styles

[ssimonson]

I have been working on my office template and would like to purge unused arrowhead styles. What is strange is that I have about 9 arrow styles that do not appear in the purge unused list under "other styles", yet I am virtually certain that they are not assigned to any elements (tags, text, whatever). Any ideas? Is there some way I am not thinking of to identify where a style is in use?

Revit doesn't allow purging everything.

• Manage ribbon > Settings > Purge Unused
• in the Purge unused window, pick the Check None option
• scroll all the way tot he bottom and there should be an Arrowhead category

IF the arrowhead in question is truly not being used, it should be able to be purged from here.
