ashley, I think keith has the right idea. If you do not have the same number of points in each cross section when you loft the model this can happen. Either adjust the cross sections or, after creating them, change modelers to the vertex modeler and "link" the extra vertexes from one cross section to a vertex on the neigboring cross section, creating a triangle. THis should remove the flaws... Come to think of it you might just want to hit "triangulate" in the vertex modeler and it should solve the problem. mike
