[Closed] Get Border Edges Using Face – EditableMesh

How would I go about this??

I know its easy to do in Polyop, but I have to use a Mesh. Well… I dont HAVE to, but I am using the MeshProjIntersect() to get the closest face in the mesh to a mouse Position, then would use that to get the border edges that are attached/closest.

Basically I am trying to get it so I can autodetect an open Edge/Border to extrude in Script without interaction.
