Need to Rebuild Surfaces to Diagrid them

Hi Guys,

Im new in this forum.

Firstly id like to thank you all for providing such an useful base of information on the workabouts of GH.

I need to remake some surfaces that come from the intersection of a spiraling ramp and the outter surface.

After I do these Im in need of making a diagrid of them, but in order for the nodes to coincide, the surfaces should be perfect.  So I need to rebuild them from the vertices left of the previous splitting operation ( tried with shrinktrimmedsrf and doesnt get much better).

I Debrep the resulting faces to get the vertices and make new surfaces from the vertices, but the list seems to be in complete disrder, so cant figure out hot to match them.

I tried it once with a simpler form and it worked, but here the points oput of the deBrep seem to be out of control. 

Is there a way to order them so that the Cull works?

Ive been fighting with this all day long, searching everywhere for a solution.

Hope you guys can give me a hand.

Thanks a lot in advance!!!

Cheers
