Normal transform orientation doesn't work with edges

[eobet]

PROBLEM

Normal transform orientation feels very random with edge selections.

Why isn't the normal of an edge the median between its adjacent faces?

Scenario 1, what determines the seemingly random angle of this line: [2018-12-10_11-09-50] (Here’s how I’d expect the normals to orient:) [2018-12-10_11-19-41] Scenario 2, again, what determines the random offset angle of this line: [2018-12-10_11-21-41] (Again, here’s what I would expect it to look:) [2018-12-10_11-22-54] Where does this random looking rotation to the edge normals, compared to its adjacent face(s) come from? It’s really annoying to have to select a face and add a cus…

SOLUTION

Normal transform orientation should attempt to find an average normal plane for the current selection.

In the case of a single edge selection, it should find the average normal plane for the adjacent faces.
