The 'purge unused' button is greyed out when editing the pens attributes. <BR /> All these rainbow coloured pens have no use to me and It just makes it a little messier if I want to edit pens or change the pens of an element. Anyone have any answers to why you can't delete pens, you can only edit existing ones? I know it must be possible, but it doesn't seem obvious.</T></DIV> Fri, 26 May 2023 13:29:24 GMT Anonymous 2023-05-26T13:29:24Z https://community.graphisoft.com/t5/Project-data-BIM/purge-unused-pens/m-p/63349#M13375 <DIV class="actalk-migrated-content"><T>I haven't used the attribute manager that much, but one thing I found very useful was the ability to purge unused materials.
