Add_face method using points and arcs

[medeek]

Normally I use the add_face method to create a face and looking at the documentation I should be able to use the same method where I have a number of points along with a couple arcs that will define the geometry of the face. The funny thing is I have never run into this before, I've only had to deal with polygon faces (only straight segments) or circles.

Does anyone have an example of creating a face with the add_face method that involves straight segments (ie. points) and arc(s)?
