May I ask why the control points are arranged like this

[Hershel]

Why deform the controller, the middle points are evenly spaced. As far as the outer two rows go, the spacing gets smaller

Networksrf rebuild - homogeneus control points distribution for flow?

@pascal, looks like the geometry library function that does the actual rebuilding extracts isocurves in the middle of surface domain in both directions, splits those into requested number of pieces and extracts the parameter values of the splits, and uses the extracted parameter values for constructing the new surface. Meaning the rebuilt surface isocurve division should be even right in the middle of the surface, and in many cases uneven elsewhere. Attached is a simple but extreme example. The…
