Constrainin Points to a Circle?

I am wondering if it’s possible to take the highlighted verticies shown here:

And form them into a perfect circle. I had thought there was such a function but I don’t remember.


Enable Loop Toolsaddon that comes with blender and use its Circle function.

There is also the ‘To Sphere’ function (Shift+Alt+S) that may or may not work depending on your mesh

That did it, thanks Richard!
