# Rotate curve around x axis [closed]

How can I solve next problem? I have a curve and area which I need to rotate around x axis to make a sphere. Can it be like an animation? So far I made a half of sphere, and a whole sphere, bit I don't know how to animate it?

• If you want an animation of this you probably need to be a bit more specific regarding your expected result. – kirma Jan 20 '19 at 16:13
