folding origami beyond basics-kangaroo-hinge

Hi i am trying to make a folded origami simulation, I have explored the examples people posted but there don't seem to be any tutorials so I am not understanding it properly, especially when C# is involved.

I have attached my file when I was just understanding the basic principles of what the tools do by using two triangles but eventually I would like to do the fold pattern also shown in rhino doc.

If anyone has any suggestions of how to approach this or tutorials I would appreciate it

Thank you

Sarah

What part are you having trouble with?

- You have to convert your triangular breps into a mesh object (you can use the simple mesh component).

- You'll have to explode the red and blue curves into individual segments (either in rhino or grasshopper after referencing them).

- In this case you won't need the grouped components at the top since you don't have quads.

What the main C# component does is the following: for each mesh edge that shares two faces, outputs the 4 points you need to create a hinge force (it also triangulates the mesh but you don't have quads).

The final C# component unwelds the mesh but you can use the newer unweld component with an angle of 0.

thanks for explaining it all!- before you sent this I tried another method of attaching triangles then tried to do the same thing but with lots of triangles, I was able to do this for the second 'pari of triangles by merging the adjoing edge, but the next time I did it one of the corners didn't ajoin.....

What do you think to this method? Any suggestions to reproduce more triangles for it in a simpler way?

Thanks again
