Perhaps that's not available for Revit Architecture, after all. If you need one or two family files converted, post them here and I'll convert them. I currently have 2012 and 2013 installed here, so anything of an earlier release would have to be upgraded.
Thanks CADastrophe for your inputs and cooperation.
What I was doing was only exploration of this feature for my knowledge, not something related to any projects I'm working on. So there is nothing I'd like you to convert for me. But I appreciate the response.
Thanks all of you, guys!
