Here you go....

YES! I dont want to harp though. You may have this under control and just asked how to fix the gap.
"""""""""I watched the Keugmeister swagger video's on youtube many,many, many times....and if I understand it correctly
you create network, loft patches, do the Iso on the surface, reconstruct curve to polylines, loft straight and then subd.""""""""
Well, sort of. I have watched a bit of his videos. it is really a "combination" of those things you mentioned, AND back and forth. He actually does a process of creating surfaces to allow him to create geometry from those surfaces to create surfaces, which allows him to create geometry he needs to create a surface. This can be interwoven. It's not just 1, 2, 3 surface. But the end surface he is looking to create is the final NURBS. It is always a "Means to an end"... Not a set process.
