Same yet different surfaces

Hi all,

i am before you with a strange set of surfaces, if you look closely the control point positions, point counts, degrees, Us and Vs of those surfaces are identical yet there are deviations up to 25 units.

Could you please enlighten me

thank you

same degree same point count different surfaces.3dm (463.0 KB)

uniform vs non-uniform knots, I think.

From wiki “The knot vector is a sequence of parameter values that determines where and how the control points affect the NURBS curve”

Indeed, but the question is:

How can @Blastered get a grip on that

@pascal are you aware of any tools how to know there are non_uniform knots and tools to deal with that?
