I've been searching for the past 2 days for a solution to the following, and I was wondering if you guys could help me with this, or at least give me some hints. When I render two mated parts of the same color in the assembly, SolidWorks doesn't seem to recognize that they are two parts, and renders them as being one part. Take a look below. I would like the second photo below to have that diagonal that you see in the first photo, separating the two parts. Does anyone know what settings I can modify to clearly show in the rendered photo that there are two mated parts and not one? Please help.
