I'll offer one stupid tip in the hopes someone can answer one stupid question! Stupid tip: if you want to uniformly scale something in the assembly room quickly, "group" it first, then it will only scale in ALL directions at once. Remember to ungroup when done. Stupid question: Sometimes in the shader room my preview window goes all wierd.. the perspective is all funny and the movement controls work in strange ways. Trying Reset Camera or Fit Object in View doesn't seem to help. Is there some way to get it out of this state? thanks Ed
