Filling a hole in a face with loop cuts forming a 2-way intersection? I have a mesh that forms a plane with loop cuts running in both directions. Part of this area is cut out and I need to fill it back up, maintaining the loop cuts in both directions. Is there an automated way of doing this? If not, what's the easiest method?
Because the number of vertices are matching on opposite sides you can do Ctrl+F> Grid Fill:



Also found in Mesh> Faces> Grid Fill from the header menu in the 3D view.
