How would I uickly switch places different planes of my part.

Is it the only way to reorient a part by changing dorientation of my part so it is related differently to the rest of the

assembly, by mating it differently? If it is, I know how to do this myself.

Is there any way I can change this part so the shadow is on the bottom, where arrow is pointing, not at tthe side?

I can rename layers all I want, but can I change where the shadow is cast?

Thank you very much for your time, in advance.
