As much as I like creating large ships, I have to make little ships to put in them, as well as turrets.
If it's wedges that are to problem, then I have a default message for that:
I can't due to a bug where everything disappears when I use advanced build mode with any rotatable block. It's really annoying, but until it is fixed, I can only use wedges in 4 directions utilizing symmetry planes. Thanks for your concern.
