Symmetry is hard on platforms, isn't it?

I built a ginormous Enterprise D, with 4 rockets on each nacelle. I ended up doing the saucer by drawing a quarter-circle, then copy & flipping it. That was after I'd spent a couple hours trying to draw a circle the hard way.

Even now, the uneven shapes of the base bits, and the way walls connect depending on angle, make eyeballing symmetry challenging, I find.

I salute you; this is impressive!
