How can i create a circle on center and tangent of a surface?


I want to create a circle tangent to the surface and on its center.


I could only do that.


How can i do this vs. rotate / orient / align etc.?

Thank you, you’re really good at this

To be exact, these circles are perpendicular to the surface and not tangent.
