NURBS alignment difficulty

Making a model using NURBS for the basic shape then skinning. Realized that I could pull in a portion of a prior model to speed things, but the endpoints of the (closed) surface curve differ wildly between the two segments so when I try to join then face the created faces are twisted and out of place. Is there a way to reassign which control nodes are the endpoints in a NURBS curve/surface, or is it time to convert both to a mesh and do manual damage control?

If it makes a difference, I created the first by making a surface curve then extruding and the other by the method described http://wiki.blender.org/index.php/Doc:Manual/Modeling/Surfaces/Skinning although the end result appears to be similar.

>The endpoints of the (closed) surface curve differ wildly between the two segments…

Did you create the difference? Or is the skinned surface going wild. What do you mean by “closed” surface curve?

The difference is due to me building the surfaces at two different times using somewhat different methods.

The first was built using the technique http://download.blender.org/documentation/oldsite/oldsite.blender3d.org/117_Blender%20tutorial%20Fun%20with%20nurbs.html (c closes the loop) and extruding the closed loop. The second was built using almost exactly the technique shown on the skinning tutorial. Because I built the first part with a closed loop, I didn’t make sure that the “open” ends (the control points that the surface curve closes across) were at the relative top, and they’re about 110 degrees rotation away from where I need them to be. When I try to combine and reskin the two surfaces (yes I did make sure they were all using the same number of control points) I get the control points connecting with each other relative to their order from each end. This results in a set of intersetcting skinning where the two models join.

I experimented with creating a surface with NURBS curve trying to join “open” and “closed” curve segments. Problem is that once you close the curve, number of points that makes up opened and closed curve is different. So you cant create face between them.
