Hi georgewhite331,
Sorry, I guess that leaves you with the plugin option only.
Here is a quick screen capture:

If the quads are too small, some quads will have the need to be converted to triangles.
To scale would limit the diameter, but is the four points define already the diameter, then yes, the scale tool would work here.
You might make a suggestion here:

Image examples are, most of the time, super limited. I prefer scene files, as this thread proves it again.
I thought so, hence why I wrote that I’m not certain if that is working for you.
The suggestion with the holes is not limited to holes, as the alignment of the points is often done before the hole is created. Also, of course, not a one-click, most of the time.
Here is the short version, also not a one-click option, but an example of what I had in mind with the hole suggestions:

Just to be clear, there is no native one-click option in Cinema 4D to my knowledge.
All the best
