Dear Sir!
I would like to know normal vector in b-spline suface.
In Plane, To use member fuction, I find ease the value.
But how can i find normal vector in b-spline surface?
If my though mistake, How do i solve it ?
And Can i convert b-spline surface to plane ?
Thanks..

All surfaces in OCC inherited from geom_surface. So, you don't have to think of the type of surface. Just call DO,D1,D2 or D3 memeber fucntions in goem_surface as you did it in goem_plane. Unless you mean approximation, It is impossible to convert geom_bsplinesurface into geom_plane,
