Two Screen Shots: Top and Bottom
Trying to heal (close) the open surface of the top shot.
I assumed I would need to retrace with line tool all four sides of the open space: that did not work.
But what did work was a single diagonal across the open space.
Does this mean that the four points of the original surface are out of plane, that is non-coplanar?
Will I need to redraw to get the point in-plane or is there way to find the bad point and pull it into plane?
