Trying to work out a way to build a surface between non-parallel lines. I've got an attachment here to show what I'm working with - basically, I've got four straight lines connecting to each other, none of which is parallel to any of the others. I want a smooth curve, but all I get is a corrugated surface or a sharp angle formed from a line directly bisecting the region. Or a stalled plugin.
Trying to complete the missing side of this, basically.
