I've been trying to figure this one out, without a surefire way... Basically I have 4 verts, and I am creating a Face from those. Alot of the time the face is created right, but sometimes it gets created wrong and the new edge appears twisted. Like if you extruded an edge, then rotated it 180, so the verts are on opposite…
I ended up changing how I was creating, using a different interface, so now I setup Ctrl and Alt to Flip the Edge or Remove it. What a pain in the ass.
