Not yet, but I recently downloaded a CAD app to model some spaceships in, so I could 'pose' them better and make more interesting and accurate drawings of them in my comics.
I think I can use that app to nail down the basic geometries of trickier interior spaces. I'll be giving it a try, because otherwise, the living space of my scruffy courier's spaceship is going to be an absolute trial to figure out. I can use perspective grids just fine when everything is rectangles, but the shape language of his ship, other than the cargo bay, is all triangles.
