Whenever I try to fill the face connecting the selected vertices (by selecting the edges and pressing f:

I get this weird filling

So, why isn't that face filled properly? and how can I fill it smoothly?

• That's not just the failure of 'F' to create new edges spanning your new face ( which you would expect: either use Grid Fill or cut the replacement edges yourself ). Some of your edges are connecting the wrong vertices, somewhere inside the object, or doubles. Clean up, and check all the vertices on the perimeter of your hole. – Robin Betts Mar 23 '18 at 13:30
