Unfuse or Group this type of Point? {[SOLVED]}

Hi!

I have a geometry with a specific point I would like to split/unfuse. Is there a node for that? Or, is there a way to automatically group this kind of point? (I could use that group in a point split later).

Is that point always perfectly in the middle?
If yes, use a Group with 'Keep in Bounding Regions' and set up bounding box accordingly

I need a futur-proof way of dealing with those no matter what geo I'm working with. It has to be automatic, no manipulations.

Hi,
try to use PolyDoctor sop -> Topology tab -> Non-Manifold Menu -> Repair.
Does this work for you?

AHHH!!! YES!

I set every other setting to "ignore" exept the Non-Manifold Points. Works perfectly!

I don't know how you are constructing this object, but for this type of topology, that is, if your future geometry variants will be created in mostly the same way, perhaps the optimal solution is just to group points with a valence greater than four or five? Group Expression SOP comes with a predefined VEXpression which does just that. Look for "Point Valence".

It was done with boolean operations. It's for a tool to help me model mechanical props. My first step is to separate by boolean operation and this can cause points with primitives that don't touch.
