Hi Gang:
One thing I
didn't mention about OnShape, and other 3D programs, it is much
easier to use with a 3D mouse. I use a 3DCONNEXION "Space
Mouse". It allows one hand to spin the model while your other
hand works the keyboard and regular mouse. You can do it all
with the regular mouse, but the Space Mouse is cool. I think I
paid $60 for mine used.
Carl.
