Rounded edges on parts with multiple materials

[Avsha]

Hey everyone.

I read many threads regarding rounded edges but can't seem to figure out something.
When I import a single material part from Solidworks to KS6, I manage to round the edges nicely. But when I import a multi material part, with some surfaces from one material and other surfaces from another, KS doesn't allow any rounded edges between them.
In the images you can see a model I imported with pre-added rounded edges, and the another with outlined edges using occlusion mask with added contrast but without the rounded edges that I need.

Is there something I could do to make those edges rounded?

Model them with a fillet.

Rounded edges only work with object that are perceived as solids (meaning the object has the same material on all surfaces/sides). Because you have an object of different surfaces, rounded edges won't work.

Thanks Will

It was less effort the way you've mentioned.
