Voronoi Projection on Polysurface

Hello All,
I am attempting to transfer a voronoi diagram onto a poly surface much like what is discussed here: http://www.grasshopper3d.com/forum/topics/voronoi-tesselation-on-su.... I am using a combination of definitions found in this forum namely the flow along surface definition posted by Suryansh Chandra in the above mentioned discussion. However, when attempting to map the pattern onto the poly surface there is an error that I don't understand. When used with a single distorted surface everything works as expected but not when used with the polysurface form I've created. Any ideas?

Nels,

Just as the Flow Along Surface command only works with a single surface, the Surface Morph component will only transcribe one UVW coordinate space to another.

I think you'd still have a couple options, however...

You could try to figure out how to rebuild your polysurface as a single surface (or come up with a strategy for tiling single surfaces) or you could try to figure out how to tile your voronoi pattern so it could be applied to each surface type you have in your polysurface.

More specifically you could try something like the Drape command and come up with something close enough to pull to your original surface (not sure how it will work with the holes though). This is half of your polysurface.

Good luck.

thanks for the reply taz,
the drape works fine for how you have it shown but i was hoping to have some closed geometry and the only way i can think to do that is either to loft curves or find some way of joining them where grasshopper will recognize them as one surface. any ideas? here's the latest rhino file you will see how I have two surfaces that are joined but the definition still see's them seperately.

thanks for you help
