Hey,

I discovered a small bug. I sketch on na imported STEP of a PCB to create a case. For the mounting tabs I want to create circles concentric to the holes in the PCB.

I attached images and a SHPR file, but the steps to reproduce are

- sketch on plane
- draw circle
- select circle and circle on 3D shape
- press concentric. Nothing seems to happen, but one notices that the radius marker is misaligned?!?
- Klick the radius marker, adjust radius.
- voila, you have two circles: the concentric one, and the old one

It’s a minor nuisance, but bug reports are good I guess 😉

Just a short explanation: the images aren’t in the right order, the last two need swapping. I don’t want to muck up the links here. Thus I didn’t dare editing.
