Just like everyone else, I’m having trouble with fillets on extruded edges in Grasshopper. I have a delauney mesh that is producing a bunch of triangles. The goal is to be able to fabricate the mesh with 3/4" plywood. So each of these triangles is extruded 3/4". I then want to fillet the edges of on…

In that case you can create the set difference of all edge indices and the edge indices of the edges in contact with the points. [image] [image] fillet along extruded edges.gh (25.6 KB)

The S input likely needs to be grafted.

Thank you for the quick replies @Quan_Li and @martinsiegrist ! And sorry for not attaching the file. Here it is: fillet along extruded edges.gh (12.8 KB)

In order to have a matching tree structure, you also need to graft the B input on the Edges from Faces component. If all this sounds complicated, learn more about data trees here: Designing with Data Trees | The Grasshopper Primer Third Edition (gitbooks.io)

You need to generate a list of edge indices, not the edges themselves. Be careful to not exceed the limits of filleting by passing a large number to radii. [image] fillet along extruded edges+.gh (14.4 KB)

Look at the output… You need to graft the S input on the Fillet Edge component. Even then, I’m not sure if those are the edges that the OP wanted to chamfer or fillet? [image] Ali Khafaji: You need to generate a list of edge indices, not the edges themselves. The I output of the Edges from…

You’re right about grafting the S input. But it seems the edges have been filleted correctly. [image] Even though they’re not the right edges, you still can change them in the cull index component.

I forgot to graft the S input. Here is the correct file. fillet along extruded edges+.gh (13.5 KB)

Your approach is not a flexible, parametric solution. It only works as long as the edge indices don’t change. [image] fillet along extruded edges.gh (27.6 KB) Which of the edges needd to be filleted is another question?

As long as all the extrusions are still in the same direction, edge indices will be the same pattern (As far as I know).
