I have been having difficulty lofting certain shapes. I am starting with a closed polyline form and using the fillet tool to round off the corners. This is then copied and stretched and the radii adjusted. When converted to NURBS and stacked in order, the loft tool connects them in odd ways. Is there a trick to finding the correct vertex on each form? It does not seem to be a problem when the forms have a corner point rather than a curve.
