Command: _MoveUVN


#1

UV Move mode
Along tangent

Hi Rhino! :grin:

When I moved the control point of the curve, I expected U to be in the red direction, but it moved in the blue direction.
Is how to the calculation that determines the direction of UV with along tangent mode? :sweat_smile:

(Pascal Golay) #2

Hi Knead - I think I’d expect what you expect here. I’ll see what I can find out.
@Knead - I see that in Help, the command is described as:

UV Move mode
Along tangent
_The u- and v-sliders move the points in a plane that is roughly tangent to the surface.

So, I guess this is not unexpected…

thanks,

#3

roughly :confounded:

In Rhino V6, I hope to improve to be move the points in a plane that is exactly :joy: tangent to the surface.

Thank you, Pascal!
