Hello guys,
Was wondering do you know of any good sites for Cad details and Revit familys?

I suppose you have checked the details and families available here on CADforum in the "CAD Blocks" section:
http://www.cadforum.cz/catalog_en/

Yes they are very helpful but just trying to get a variety of options.
