Shortest Path through 3D Mesh

Hi!

I've been trying to come up with a definition that will allow me to make one continous polyline of mesh edges to allow me to print it with a 3d extruder on a robotic arm.

I haven't used spiderweb before but I've had a look at a few of the example files, the longest line one in particular, and thought it would be useful to use to find the optimal path for a mesh, I understand that because these might not always have an even amount of nodes I would possibly have to go over some of the edges twice, which is fine.

However I haven't been able to get the example file to work, I guess this could be because I am using it for a 3d model possibly? Any help with ideas on how to draw a path through it would be great!

Thanks in advance,

Louise

Could you please post the rhino file / GH Definition you are working on.

The problem here is that you are actually trying to find a Hamiltonian path (with some extra restrictions) where the edges are the vertices. Please look it up in wikipedia.

Hi Richard! Thanks for your reply.

I've done a bit of research into these sorts of paths and how they would work for what I'm doing. I don't know any coding when it comes to these sorts of things, but was hoping that I would be able to avoid that by using spiderweb, is it able to do the same sort of path through the network.

I have attached my file, everything in the group at the beginning works to get an output of curves.

Thanks,

Louise
