There are mainly two ways you can do that using arx, the following DevNote exposes both: 1 - First technique create an infinite plane and infinite line, then uses a ray to check if the intersection point of these two infinite entities is inside the face. If you already have two line segments in and they don’t meet, select one of the lines and hover over the gripper on the end you want to extend.
