A Bug!

Is there anyone who created first a Geom_BSplineSurface and then querry the UIso and VIso lines according to the numbers returned from NbUPoles() and NbVPoles()?

If you try this and draw all the iso curves, you will see that some of them are not inside the surface.

I think this is a bug and it is related with BSplSLib and BSplCLib.

Is there anyone who knows a solution?

Hello Erki,
I think you should query your UISo and VIso according to the Bounds of the surface (U1,U2,V1,V2) and not the Number of poles.
