HI

i am driven by need to make a GH definition to allow me creating a single network surface by strarting from a quadrangular subD, here is an aexample of the base SUBD

here are the wires obtained by deconstructing the contorl poligon

and this this the point where i’ve got to : i.e. extracting and rebuilding the contour crv with 4 single deg 3 polilines.

PROBLEM : last step i need to complete is to organize the datatree of the inner grid of points in order to be able to interpolate the inner base polilines passing trough the points ( red curves )

After this i will just sort the u and v polilines along 2 of the outer curves ans generate the network surface.

can anyone help me with the points data managing ? I am not able to arrange the points

can anyone help me ?

thanks

Ivan

@vikthor responded the same day that you posted your question and you didn’t bother to check if anyone answered!? There is no excuse for that.
