Indeed Marco I was looking for an easy way to drag the center of the circle. While making technical drawings sometimes you need to place hundreds of circles and invoking a command each time is tedious. Since MOI3D snap system is excellent I was wondering there was an easier way to just drag the center of the circle to an intersection.

It is easy to do the other way around. But as Michael guessed. I'm drawing bisect lines so I can snap its center... It is a tedious extra step.
