Separation of different submeshes

I've been playing around with houdini for about a week or so and I like it's type of workflow, but I've been trying to do different things with meshes I've made previously for fun in my spare time. One thing I've been trying to do is separate the different submeshes using the connectivity node and partition node based on some forum posts I've found. However they just delete the whole thing once I add the delete node. Not to mention afterwards I'm not exactly sure on how to actually have different geometry nodes containing these different submeshes. Any advice on how to go about this?

The other posts I saw said to put the connectivity node down and put obj_$CLASS in the attribute box, then use that same name in the rule box for the partition node and that did nothing. Another post I saw said to just leave the connectivity default class attribute and put obj_'@CLASS' in the partition. Honestly I'm just kind of confused here on what these mean or what they do in particular.

Use an object merge to copy geometry from one container to another. The group field on the object merge can be used to isolate a specific group of polygons to merge. I'm not sure what you mean by ‘delete the whole thing’ when you ad the delete node. Did you enter a group expression based on the class attribute created by the connectivity node? Something like ‘@class=123’?

Leave it at ‘class’ or ‘index’ or ‘piece’ or some other regular word. Putting an expression in the connectivity node's attribute box is incorrect. The partition node can be used to create groups that can be used to isolate parts for certain operations without deleting them, but is not required as the above ‘@class=’ notation can be used instead of creating explicit groups.
