Hi Brian,

There is actually a solution as it is - you can select the 2 edge curves and then make a Loft between them. But like I mentioned previously, that will create a surface that is collapsed / pinched down to a point at either end of it which will cause problems later on. That's why the other method is better.

It may be possible for me to add a tool in the future to fill in a hole like this where an extrusion will fit it.

That takes quite a bit of extra analysis in the hole filler code - right now it only knows how to handle a flat planar hole.
