Hi!
I'm working on some tools to clean up ugly photogrammetery geo and I'm constantly needed to make an edge group of the largest hole at the base of the mesh. Currently I'm just double clicking it manually but I need to re-do the selection when I change things up the chain. Making and edge group of unshared edges would work, except I usually have more than just the one hole and I need the group to only have the largest hole as an edge group. Any thoughts?
Thanks!
Procedurally create edge group of just the largest hole?

you can do something like this
use Divide SOP -> Measure -> Sort -> Blast -> Ends to get the largest boundary curve
ad then in Detail Wrangle you can filter unshared edges geoup by proximity to that curve and keep just edges within certain tolerance
EDIT: updated the file to have choice of measure metrics, between perimeter and area as they can each be useful for different meaning
of "largest"

Another way would be to create point groups from these edge groups, process them in VEX and output the name of the group with the highest number of points and then use the same or similar name to get the corresponding edge group and then use this edge group to do whatever you want.

I mean since you have to have both the edges and point groups, you can create names with suffix to identify each type or just convert edges to point groups and get rid of the edge groups and perform the attribwrangle on that branch and read the result back to the main branch since the group names will be the same.
