print 3d pdf so it doesn't show the triangle in viewing

Question

How do I set print to 3d pdf settings so that when I view the 3d pdf it does show Triangle lines in solid, solid wireframe or illustration viewing mode? 
 I didn't have this issue prior SS4

You should be able to control the initial "Display Mode" of the U3D in Acrobat by selecting Settings->3D Plotting->Display Mode in the print dialog. By default is set to "Shaded (Solid)".
