Simple solid intersection - fail :/

Hi all,

Trying to find the solid intersection between three Breps (have a list of 23*3 breps).

What I want to do is overlay them three by three and find the volume they have in common. When I try to use "Solid Intersection" it only returns 15 intersections, eventhough many of the brep sets are identical, and it is pretty clear visually that they share some volume.

I'm pretty clueless to why.

Anyone who can spread some light on this will save my day! :)

23 Initial brep sets:

Only 15 intersections found:

Added some visual clue(s)

Of course the simplest way is to sample the 2 groups (2nd set in Diff) into a single parameter

Thank for the quick reply! :)

Well, not sure what goes wrong, but at my end I am still only getting the 15 intersections. Could it be a bug? If your "Solid Intersection" component seems to be working in this definition? :/

I have GH version 09.0076.

Karma maybe, what else?

See V3 (Added Plan A that does it with 2 ways: set VS set and sequential as Joseph indicated). Testing the C# VS the GH component appears that the latter works with the sequential mode (witch makes more sense: I mean a set VS another: is a bit ... hmm).

Anyway it works fine here with 076. Maybe a SR issue? a tolerance issue? a what?

Note: load R file first
