[Closed] Arc or Circle through points script?

I need a script to draw me an arc starting in one point and ending in another (and be able to ajust the “hight” of the arc).

The reason I need this script is that I have problems doing this interactively in the viewport (the points are very far apart and the “height” should be very small), max simply will not make me do that with snap on … and if making a bigger arc I have no way to ajust this so that it still goes though those two points.

A script to make a circle go through two points (where I can ajust radius) would also do the trick I think.

Anyone know if such script exists… or can help me get started on this?
Thanks
