constrain center of torus

[pcmdanb]

I'm trying to create a lug on a part using the torus command. I've created a sketch with a point where I want to the center of the torus to be located. However, when I use the Torus command, while I can easily select the plane I want it to lie on, the best I can seem to do with the center point is snap to grid close to my point:

It may be difficult to see, but the maroon dot just to the right of the cursor is the location I'm aiming for. However, nothing seems to be directly selectable during the "place center point" step. Nor do I see any means of selecting the center of the torus and re-defining it with a constraint afterwards. Am I missing something?

I do know that if this doesn't work, I can always revolve a circle to accomplish the same thing. But that would involve creating an additional sketch plane and an axis, and I was hoping the torus command would be a simple alternative (I'm trying to learn to use all the available features at this point in my F360 "career", rather than simply brute-forcing the basic tools. Gotta learn sometime!).

Thanks in advance for any tips.

the only way to constrain the center is to put it in it's own component and joint the origin of that component to something.  Mostly i would advise not bothering with the primitives.

If you do want to use the torus and both are bodies, you can place a construction point where you want the torus to be. The torus will not snap to the point though so place the torus anywhere. Then you can do a point to point move of the torus and align it with the construction point.  If they are both components, you can place the torus with a joint.

Well, that will certainly work. It seems kinda kludgey, though. Looks like a revolve will be the cleaner solution.

The primitive shapes can cause you all sorts of headaches later. I strongly suggest modeling your lug in place.
