factor set? (I am using the GUI initially.) The coordinates in
the STEP file are consistent with my CAD model. When I save GEO and
MSH files from gmsh the coordinates all seem to be scaled by a factor of
1000 for one model. However, for a second model the scale is
correct.<o:p></o:p></span></font></li>

non-uniform weights, repeated control points and multiple internal knots
