I'm building a rocket to which I want to attach a rover. However, when I build the rover I get the radial symmetry thing going on, which makes it impossible to add wheels in a rectangle. How do I disable the radial symmetry and let it attach perpendicularly to the surface of the rover base (which in this case is a rectangular block)? Ps. the "Forgot password" function might not be working, it never recognizes the captcha. I had to fix a new account.
