UV grid creation

[cn22tg]

Hello,

I have recently been making UV grids and cant figure out when revit chooses which grid to create, it feel very random and illogical to me, sometimes i get a grid following the outline of my shape and sometimes the gird is based off of one edge of the shape like in the examples, are there ways of changing that?

Its not random...3Each surface has an X/Y/Z positive vector orientation. As long as that surface is flat, the UV should follor the X & Y vectors of that plane and not the sides/edges.When the surface is not a plane, the U/V then based on the subdivisions of the edges
