Hi Michael,
It seems like BoundingBix should work for this.

I was wonderimg about it’s calc being too loose and creating peer’s “inaccuracies”

Could there be a tick for “high accuracy” that could be enabled for particular sets when needed? So like bumping the tolerances for BoundingBox calc from .001 to .0001

So not bogging down the normal ops, but when needed, one is willing to have it be slower.
