How do I draw a torus in unity?

I'm trying to figure out how to draw a torus in Unity. I would like to be able to control the large radius to small radius ratio, I can't do this with an imported 3D model because there is no way to scale the two parameters independently.

Use the Mesh class and whatever math is necessary to make a torus.

Go to the Asset Store and search 'primitive' there are at least two low-cost packs there.

Not possible... Look up the differences between a 3D Modeling software and a Game Engine. They're different, although many people don't seem to understand that...

Anyways, make it in 3D Modeling software, then import until you get it how you want it to be.

Good luck.
