Origami component

by Tülay

Sep 28, 2017

Hello all,

(I had asked this already in the general forum, so sorry if you are seeing this again, but I thought this group would be a better place to ask.)

I used the Origami component to fold a mesh, but some fold-lines do not fold as intended, as can be seen in the top-view. I wanted them to fold just like the first part, as a harmonica-fold.

I used "Weaverbird's Unify face windlings" which was no solution as it just transferred the problem to other fold-lines of the mesh.

Do you know if what I am doing wrong?

Thanks,

Tülay

    in your case the folding lines have 2 DOF(XY), it makes sense why they bounce away. Even when you fold it in real world it will physically perform the same result.

     

    If you want them 'slide' along a given path you can constrain the points I marked using AnchorXYZ(make strength x much stronger and weak strength for y)

    or simply apply goal 'onCurve'. That guarantee that your origami never jump aside.

      try this, however, I will recommend you try K2 to get better constrain. For example CoLinear...
