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 )

20200425 SQUARE SUB D TO SQUARE NETWORK SURFACE.gh (19.8 KB)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
