I'm in my file right now but I can't see any way to alter the thickness of a floor. It only has an area to change thickness for the optional baseboard, which I didn't want or need on the light. Under Preferences I see an option to change the new level floor thickness, but but that doesn't seem to be what I want. I'm trying to modify the floor in the initial stage where I first created it. I also tried modifying it after I exported, and then imported it back into the program, but at that point, it's part of the whole object and the brace was already set for 6" thickness. What am I doing wrong here?

Wait, so if I made the color of those panels bright red, I'd get a red light? It makes the color and surface of the panel automatically translucent? When I've been working with the light panels, when I rotate them a certain way, when I get to the opposite side of them, they often disappear or turn invisible, so I assumed that whatever 'color' I assigned them was just replaced by whatever the program uses to represent illumination?
