Hi Psygorn so if you do mean "Arc through 3 points", 3 non-collinear points already fully defines a single unique arc and so there isn't any way to set up a tangent additionally there.

I'm not sure that there is a built in tool in MoI currently that will generate a circle by tangent and 2 points on the circle. It can be calculated with this method:
