Flow Along Surface Issue

[David45 (David)]

Is there a way I can convert or rebuild a polysurface into one surface? Or Flow along surface to a poly?

Is there a way I can convert or rebuild a polysurface into one surface?

It depends on the shape of the polysurface. Post a .3dm file with the polysurface.

Hi David,

simalar question here:

Accurate pattern on polysurface

Hi friends, I have a problem in having an accurate pattern on a shoe sole. The sole is not a surface and due to rised edges,we have a brep. I can not have discrete pattern on each face,it should be continous. I can not have a surface with tools like network, it should be qite accurate. I can not use twisted box mesh because my pattern should be continous again. I tried paneling tools both in rhino and grasshopper but i couldn’t reach desired result. maybe I was’nt good enough at it. I even doubt…

ExtractWireframe made 212 curves - too many for NetworkSrf. Patch made tilted back. My best guess is that NetworkSrf will work if you delete most of the curves. Sweep2 and SubDSweep2 may also work if you convert the edge into two rails and delete all curves parallel to the rails.

Probably the fastest method is making one dozen cross-section curves with the help of Contour command, then converting polysurface edge into two rails, and finally running the Sweep2 command.

There have been many of these questions lately.

FlowAlongSrf is not a magic “apply treads to a sole” tool, all it does it effectively “map” objects from one surface to another. So your target surface needs to be a) A SURFACE and b) actually laid out with this behavior in mind. It’s probably not literally just a sole with no tread on it.
