Hi Emre,Our NURBS objects are defined by structures on disk(ie, read in a file that contains the control points and knot vectors) and then the object is rendered. The selection part of our interface allows you to move those control points around to modify the shape of the original surface. We don't have support for redefining the NURBS object such as control point addition/subtraction, knot insertion/removal. biv
