19:54 <Ademan> is it possible to constrain two circles to be concentric "directly" ?

19:55 <Ademan> I accomplished this with four line segments, two perpendicular to the other two, but this seems awfully indirect

19:56 <Ademan> *also* I would like to constrain a drawing such that a margin between a cutout and the edge may *not* be smaller than a certain value, but I don't see any sort of "minimum length" constraint

19:58 <swivel> Ademan: for the circles can't you just select both their center points and press 'o' ?

20:00 <Ademan> swivel: ah thanks! not sure how I missed that...
