@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 surface on the left was rebuilt using 10x10 points.
