Merge or join surfaces generated in sverchek . Curves made by Bezier Initially I created bezier lines in Blender. Then applyied Sverchok.  Visually I devided a shoe into some areas(6-7)  and according to these areas I generated surfaces through Sverchok. Now the problem is - how to join these surfaces together into one?  Because between generated surfaces I get some holes. So there is a way to fix it ?  to merge ?
for now it is one solution

but we need sewing node, that will do it between zero-space between surfaces.
