Maybe it is time to clarify some misunderstandings here. Twisted Symmetry is correct when he says that this is a loft, simply because in Max(Probably GMax to) the loft begins as what some programs calls a Sweep, extrusion of a spline along a path. In Max they have basically merged the two tools. When you have extruded the spline along its path (Sweep), you can go into subobject level and insert new and different splines and then you have a loft.... And to compare Rhino with Max is pointless, since the NURBS tools in Max are almost useless (They implemented them in version_? and haven`t touched them since). It is like comparing Rhino and Max on a Poly basis....
