geometry : how to create an arc of a circle ?

Discussion created by nickdis on Jun 30, 2014
Hello, I would like to create an arc of circle on a map layer.

What is the best approach ?

Right now I am drawing a circle from two parameters : radius & center. I would like to be able only to draw a "part" of this circle (like : a quarter of circle, a semi circle, etc. ).

Thank you
