I want to assign different materials to my surfaces. When I don't have any cuts through my structure, this works perfectly. But as soon as I cut out a quarter I am not able to assign a material to certain surfaces. I think the problem has something to do with the same feature (helix) being cut into completely detached bodys and surfaces.
This is what the structure looks like:
I would like to assign a appearance/material to all marked surfaces (red for carbon; blue for white plastic), but what you can see in the image is as close as I can get. I can select the missing surfaces, but I am not able to select a material for them. Am I doing something wrong? Is this a bug?
Any help would be greatly appreciated. I attached the model in question.
