Okay, I just thought you have something particular in mind.

Hey guys! Just stopping by and sharing how the third circle came to be:

You can probably trace what I did here... I was following Jean Lemire's guide (thank you very much for that, by the way!) and found a pretty simple method. I drew the tangent of the first circle you suggested I use and then drew a line from the radius of the second circle off to the right along the red axis. I found the radius of the third circle was exactly one-half the radius of the second, so I made a line of that distance and aligned it to the green axis at the point where the tangent and the radius-line-thingy met. The other end of that line was the center of the circle, and from there I drew the shape. 😄

That may be unclear, and if so, I apologize... I didn't bother to label the lines or anything. The only thing that bothers me is that the first and third circles don't exactly meet up, but it's understandable considering they're all using under 40 sides. It's not very noticeable from afar anyway.

Eyeballing? Doesn't sound very accurate......

It is'n't accurate indeed, but often quite enough to cut out the image part you need, say for a new 'Face Me' component. Then inferencing other than 'On Face' gets in the way. That was my point. I can't think of another time disabling inferencing would help at all.
The main reason for answering here was that other axes (as in the question by OP), like R/G/B with 60/60/60 degrees is possible.

If you would like to exchange suggestions about working around the orthogonal axes as mentioned in this thread:

let me know in that thread. (here we are to much off topic, sorry)
Unfortunately, in that thread your uploaded image contradicts what you are writing. So I'm not certain why you cannot just do what you are after without disabling inferencing to axes or disabling whatever.

Simple when drawing the geometry hit the ctrl key and it will switch to the circumscribed or Apothem method.

Yes. It is simple since SketchUp 2015 was released. Prior to that and when this thread was active, SketchUp didn't have this option as a native feature.
