   Getting a single face in trueSpcae 6?
  I am making a model for a gun which is an example from the book i am reading and I cannot get two spheres to have one face when I used the object union tool.  Any idea why?   
  Nevemind, I figured it out.  I had to have the object face tool selected and then I could click on the face of the two spheres and change its location on the X axis to match.
