I have an issue for some time with face colors in assembly.
So i have a sheet metal part with a material assigned and some faces are colored green.
In the first assembly ("welded assembly"), in witch this component is mounted, the faces are ok, so the green color is visible. In the "mounting" assembly (with nuts,etc) the color doesn't show anymore.
The color is there somehow because if i make a section in the assembly the color appear. This usually happens on old assemblies. I tried to create new ones and this issue doesn't happen.
I am using SW 20165 and 2016. I have attached the assembly and components for reference.
Please let me know if you need more info.
