I can't make plane from circle

A special condition is that circle was created with the fillet algorithm
, i didn't make it

You can use a mate connector as the plane in this location.
This is a great tip that overcomes what users first see as an inexplicable restriction. It would be great if onshape either allowed users to create plans from circles (after all, every single point in a circle is on the same plane), or put a hint in when someone tries to create a plane from a circle, or even just add the mate connector button to the dialogue box when you try to create a plane. Do something that makes it just a bit easier to get used to/ figure out some of the seemingly illogical restrictions that are difficult to work out at first.
curious, why specifically there do you need a plane? What is the use case?
The use case is having the convenience of a named plane to do someting on (Sketch, Intersection, Extrude-up-to, …). We can have have plane-point planes, why not define the offset by the circle? A circle would count as a valid point or even plane, IMO. That said, I'd go with the mate connector in the circle center.
LOL. well I understand that and don't disagree but what I meant was what is a real world example where your using a tangent fillet edge to determine the source of feature definition. Not knocking that it shouldn't be possible, just curious to what led to the realization one couldn't use it for a plane.
There seem to be a lot of weird cases where certain references can be used to create planes but not mate connectors or vice versa. I know I've said this before, but the people who work on these two features should really talk to each other and coordinate (no pun intended). I really can't think of any reason that planes and mate connectors couldn't be the same thing. They really are only different in how they are displayed. Other than that, they both define a plane with an origin and X/Y directions - i.e. a coordinate system. Given that, the references that are used to define them, and the things that can be done with them should be identical.
@MDesign Well, I was more or less referring to a generic case. I'm just working on a design that has a lot of irregularily shaped small moving parts and bearings in odd angles. Parts are too small to actually pick proper faces or have none in the right place, but all these circles (e.g. cylinder cap faces) would have midpoints.
I second @S1mon in his approach of unifying MCs and planes. Makes all sense to me.
