Re: Slots/elongated holes

Circles aren't supported, but you can use two arcs to make a circle.
Arcs work correctly. There are several in the set of boards I made, as shown in the pics I uploaded.
Let me know if arcs work for you.

Jj did you come to fixing the arc/ circle bug? Im making a ringlight
