algorithmic modeling for Rhino

Hello I have recently came across the "Entry Paradise Pavilion" in Germany and was wondering whether someone could point me in good direction on how to model it using grasshopper? I would like to be able to move centerpoints of the nodes as well as their thickness and length.


Thanks in advance for any suggestions

Ive been having trouble breaking it into such clean areas.  My goal is to flatten and sew together. here is what mine is ending up like:

I have attached my files below, thanks!



Thank you Daniel for this explanation. I forgot about ExtractConnectedMeshFaces and it works very well here :) 

I have a question about the relaxation you did in the example above. When I try to do it myself with the same shape I keep getting slightly finer mesh - it seems like each of my quads is divided into another four.(see my result to the left of yours)  Iwould like to relax it with the minimum amount of quads so that when I have a more complex network it is faster to select the stripes. Could you tell me how to do that?

The increase in the number of faces comes from the WeaverBird CatmullClark step. You can decrease the level of subdivision, or skip this step altogether if you already have a mesh with enough faces.

Ah right, perfect. thank you!!!


(hm there doesn't seem to be reply link under you last post...)

Hi everyone


Has anyone been able to get the Streched Fabic Code to work with either the latest release of Every Thing... Rhino V4 (SR9) or V5 (16th March) GH 8.07 ??


In V5 I get the error noted in this tread when i open the GH file about a Corupt Chunk... and in both rhino v4 and V5 a final relaxed mesh that does not look like the one pictured using the same files. But no idea why.




Ok Fixed the Bug. It seems UTO Latest Mesh Edit Tools has a new vertices output that GH was automatically plugging in instead of A thus giving you a random set of points and not the edge points.



Thank you!!! now it works perfectly!!!

I have figured out a way to cleanly break up the pieces for fabrication.  There is a program called Unfold3D Magic used by video game artists that flattens .obj objects for imaging in photoshop to then be applied as materials on the objects.  This can easily cut the object and flatten the pieces.  I have attached the program below and an image of the results.


The program requires no installation, just open the program directly from the folder and export your Rhino file as .obj.

Here is another program to fabricate with a folding paper methodology.

Impressive work Andrew!

I am trying to use this program to unfold and I managed to get the pieces like what you showed above. I am wondering how you exported the 2d geometry to CAD software(Rhino/AutoCad) in order to fabricate the pieces? I m having trouble with getting the 2d geometry back to Rhino-it keeps opening as a 3d object.

Thanks in advance.

So im trying to use the unfold 3d magic software can you please walk me through the steps you went through to flatten your piece. -Thanks
