One other thing that Im prob over complicating is I have a list of edges that I want to fillet in a brep but I want to target only those that are at a particular Z value So List 1 = Full List Apply criteria of Z = 0 for truncated list Thanks for any help

Sure here it is I was thinking purely in terms of abstracts but of course it makes sense to attach a file. Have tried to simplify and internalised the list Sort List Based On Z Criteria.gh (84.7 KB)

Cool! Thanks so much So you use a series component basically as a dynamic iterator for the list and the equality as a boolean for the pattern input to the cull…nice Will go and chew on that for a while :slight_smile:

[image] M Wesse: So you use a series component basically as a dynamic iterator FilEdge (Fillet Edge) ‘E’ input expects a list of edge indices, not edge curves.

Sure. Just translating the loop concept and series being the parallel of loop counter to go through the indices…makes sense…for me at least Once again…gives me heaps to go on with and finish the bits. Is there a reason to sort the list first? ie when the Z coordinate, in my case is 0 and not MIN? …

[image] Joseph_Oster: Huh? On the implicit understanding that Im migrating from text coding eg Python etc…takes time to map those concepts onto the graphic code of gh…thinking out loud for anyone else in the same boat. [image] Joseph_Oster: I did that to find the lowest Z value. Gotch…
