Can anyone say please what is the 'proper' way of transferring (i.e. copying) mullion profiles between projects (I'm thinking of the supplied System Family curtain walls).

The profiles don't seem to appear in the Transfer Project Standards checklist.

I can use the clipboard to copy and paste the whole curtain wall containing the mullion profiles I want, between projects and then the mullion profiles appear in the target project but it seems a bit long-winded... although it helps that Revit doesn't seem to let the Paste override the curtain walls in the target project.

I wondered if mullion profiles could just be copied independently of the curtain walls?

thanks.
