Primitives > Sphere.
2. In any viewport, drag to define a radius.
As you drag, a sphere emerges with its center
at the pivot p oint.
3. Releasethemousetosettheradiusandcreate
the sphere.
To create a hemispher e:
You can reverse the order of the following steps,
if you like.
1. Create a sphere of desired radius.
2. Ty pe 0.5 in the Hemisphere field.
