Fill in missing point in grid I was doing some destructive work in Blender when it frustratingly crashed on me. I was just testing a few things.

I was trying "Dissolve vertices" on my mesh, and ended up with this when I reloaded the project again:



I tried F to join each edge, but it made a strange tugging-looking mesh.

How can I fix this grid mesh, by adding the point in the middle and all the other edges?
Standard way is to remove tha Ngon face and use Grid Fill to fill in with quads. Another a bit less fast way is to use either Connect Vertex Path tool (J) or Knife tool (K) to cut edges according to existing geometry.

However there might be another way without removing that face:


Press Alt+P to poke faces.
Press Alt+J to convert tris to quads.




Note that it depends on geometry what resulting topology you will get. Also note - Grid Fill restores the curvature of the filled surfaces, this way doesn't.
