How big is the layout above?
I think a small text graphic of the measurements along the baseboards would be a nice addition to the 3D view in SCARM. Even just the max length/width in the far corner would quickly answer the math problem we do haphazardly in our heads each time, guessing at the size of the curve-to-base with visual estimates...after zooming to read the curves sizes...if we bother to, or can see them.
PS- Did you see the Wheather to weather thread? A girder bridge in it, had some very large patches, of very orangey, orange rust "growing" on it that you may want to look at.
