Wrong shape with proportional editing So I'm currently trying to bend this plane around a corner:



I turned on Proportional Editing and moved the rightmost vertex on the Y-axis:



This creates a problem. The arc that is created goes in the wrong direction. I want it to confine to the correct arc that I drew:



This looks like the kind of shape I want (taken from a UV Sphere):



I've already tried manually dragging the individual parts of the arc to the correct places, but it makes the arc look really artificial and rough (which is not ideal, considering that the model I'm making is supposed to be organic and natural-looking). I have tried different falloffs, but those did not work either. I also tried moving the center of the arc to the correct place with Proportional Editing turned on, but it also results in a very weird looking shape.

How would I go about solving this? I would prefer it if the solution used Proportional Editing, but I do not mind if there is a more efficient solution that does not use Proportional Editing.
You need to use the Sharp profile.
It's the only one that bends 'inwards'.
