When I open my 3D model I want it to start in a
certain view and I can't figure out how to change this setting. Help please!

Are you saving and naming a view via the View Manager?What view do you want to start with?Maybe you need to set up a new template instead.  What one are you currently using?

I'm using one of the native templates from the 3d pdf converter from tetra4d. 

Here's a video about this...Hope it helps!http://youtu.be/7bbzzrU1V68
