Switch gimball between U and V alignment?

You can set the gimball to object alignment, but I can’t find a U or V toggle.

I know Rhino is aware of this, because I can clearly see the red line of the other direction being drawn:


But how do I switch?

have you tried with relocate the gumball?

Thank you!

That’s a bit of a manual operation when the red line is already right there, practically begging me to click it, :wink: but if nobody else comes forward and points a more obvious thing to do out to me, I’ll accept that as an answer.

I agree it’s a bit tedious but the object aligment depends of the boundaries so relocating it can be more precise or accurate with the surface UV layout.
