Hi y’all!
I’ve used Fillet Edge in the past on simple objects without any problems but right now I’m working on a pattern that would create en open brep/polysurface and I’d like to fillet the edges marked in red in the screenshot. Can somebody point me in the direction of what I’m doing wrong or a better way to do it?
Could you fillet before you doing the array…
doing that, you could extract convex and concave edges for one tile, fillet and then array
Thanks, Martin!
The problem with that is that I want to be able to make the fillet parametric and random-ish, like the offset and fillet of the curves at the beginning of the script. The screenshot shows the pattern as squares and all with the same shape and height, but I made it so that you can play with different sizes, height, etc.
I think your main difficulty is to find the EdgeIndex - that is the index in the initial EdgeList of all Edges - and not in the partial List of interior Edges - with different indices.
its straight forward with a script component as all properties are directly accessible:
private void RunScript(Brep brep, ref object indices)
{
List<int> edgeIndices = new List<int>();
BrepEdgeList edges = brep.Edges;
for (int i = 0; i< edges.Count; i++)
{
// skip naked edges
if (edges[i].Valence != EdgeAdjacency.Interior) continue;
// skip open curves
if (!edges[i].IsClosed) continue;
edgeIndices.Add(i);
}
// Write your logic here
indices = edgeIndices.ToArray();
}
and quite a hassle with vanilla gh.
you have to re-identify the interior, closed edges in the initial edgeList and then generate a List with indices …
(maybe there is a simpler gh solution)
find both in attaached gh file
hope this helps - kind regards -tom

@Tom_P identifying closed edges in the original list was in my mind but I couldn’t figure a way to do it (still learning). Thank you so much, this opens a lot of doors!
At least for what is shown above, concave and convex edges should be easy to extract with grasshopper.
