@tig said: The 'Utility' tools that ship with SUp include 'Create Face' - you need to activate these from the Preferences > Extensions dialog; you then get an item under menu Tools > Utilities. Alternatively there are other tools... Try Plugins Index > 'AddFaces' [TIG] or http://www.smustard.com/script/MakeFaces [note you also need to get 'progressbar.rb' for this tool] thx.
