Hi Roland, There's are various known methods to extend 2D curves to 3D surfaces, like NURBS, Catmull-Clark, Loop subdivision surfaces or T-Splines. I can't tell from the description, but maybe you derived a similar algorithm independently? For some new surface representation to be added to Blender I guess it would need to have compelling properties that existing algorithms don't have.
