Hi All, thanks for the support & kind words!
Yes, the model & flat are linked in a family table. Somehow I saved the flat pattern, which now overwrites the instance in the family table. (Kinda silly IMO..) so, deteted the file, and all is good..
Yes, i do have a habit of regening & saving often, as there is NO warning if you close a window... all then is lost..
Stuff 'in memeory / In session' has burnt me once or twice, as well as "oops, forgot to save".. a consept that is taking a while to sink in...
