In most 3D modeling applications nurbs can be continuous and seamless.  Is this possible in Away3d?  Or, are all nurb objects a manipulated grid of points with a definite beginning and end(border points)?  If so, is there anyway to have the beginning column of points and ending column act as one (think wrapped around and overlaying each other).  Right now, because there is not another column following or proceeding them the curve for that area of the mesh is not constant with the rest of the mesh.
