how do i change the radius of a uvsphere…thanks!!
you scale it
there is no way to change it when you create it
[it when you create it is 1.414 units iirc]
You scale it by Hitting the S key. Or in object mode you can hit the N key and set the size numerically.
If you mean to set the radius specifically, as in by actual measurements in meters or whatever, you can’t. You’d need a CAD program for that.
Please read the online doc though, (see sticky thread above), this is super basic stuff.
