Working on a multi-body part with hundreds of features and 15 different bodies.  I stupidly tried to experiment with making one of the bodies into a sheet metal part so I could do a jog.  I clicked "convert to sheet metal" command and it totally screwed up my model.  Didn't realize until I had already saved and there are no "undos".  I deleted the sheet metal feature but now I am stuck with ugly "cut-list-item" folders for all of my solid bodies.  Is there really no way to get rid of this?  I can delete the folders but my bodies are still in this weird collapsible tree format.  I just want it back the way it was.....  any help would be appreciated, thanks!
