Hi guys. This is a very unfortunate design flaw, as it's almost always the case that when one is creating solids for 3d model details, concrete is NOT the material. In my case, I would certainly set the material to a solid color before mocking up trim, stair, railing, beam, etc details. The ability to set a default on this would be so helpful. Of course, if you did set a default while working on this or that and then want to set a different default while working on something else, you wouldn't want your previous items to change to the new default and thus there would need to be a sticky concept as well.
