Layers and layer rules are unfortunately still too confusing. We're working on making them easier, but there's still more to be done...
One thing to understand is that if a feature is added to a layer and that layer is hidden everything owned by the feature that's able to be hidden will be hidden. So, if you have a sketch with curves and geometry points and you hide that entire sketch feature, you'll be hiding both the points and the curves.
To be able to segregate what you want hidden you need to avoid adding features to the layer but instead add only the entities that you want to hide.
Here's what you should do:
The Look for: field in the Rule Editor dialog is the field that determines the type of thing that will be returned by the search and the type of thing to be added to the layer. In your case, this should be set to "Point". This will populate the layer with only the point entities and not the features that own the points. The Look by: field sets the search criteria. Here's where you have the flexibility to determine which points will be added to the layer.
If you want to have a general POINTS layer that contains all of the points in the model regardless of the feature type that owns the points, that search would look like this:
Here I'm looking for points (the things that get added to the layer) and I'm looking by points (meaning that the search queries all of the point entities in the model to see if they meet the criteria) and the rule is ALL, which is found under the History tab. So this search will find all points in the model.
If you wanted to get more granular and only collect points owned by a sketch and not include points owned by other feature types (such as datum point features), then you could do the following search:
Note how the Look by: is set to Feature and the type is set to Sketch. So the search will query all features in the model to find those of type Sketch and then add any points that are owned by those features.
I hope this helps.
Decided to take one more look at this after lunch, Started with a fresh model this time.
This set of rules puts all point geometric entities & all sketched features that create same, onto a layer.
Note: If feature 6 is on some other hidden layer, pnt3 will not display when this layer is set to Isolate.
This brings to my mind a question I think you layer gurus can provide much quicker than scouring the PTC documentation:
what is the difference between "excluding" items and removing them from the layer's items list ? For example:
Here, I used the "Exclude" function on DTM2 item in the list. But why would I use that instead of the "Remove" function? They do different things to the list, but the visibility effect seems to be the same... I never use the exclude function, but I am wondering if there is an advantage to it.
Layers with rules that have the associativity checked, will be repopulated according to the layer rule every time the model is regenerated. Removing such items is temporary.
Exclude is for exempting items from layer tree's item list, no matter how they came to be added to the Content tab.
For items that were added manually, It could be useful to exclude those items from the layer, instead of removing them. It would be possible to return to the layer properties later and easily change the status back to included, saving the effort of tracking down just what those items were. If that isn't a consideration, use Remove.
Actually, I think I found exactly what you're looking for Doug. I think Raphael is close, but if I understand you, I think this will work better:
This puts ONLY the GEOMETRY points in a datum curve on a layer, not points generated as stand alone points, and does NOT put the curve itself on that layer (in my case, layer: 01_HAS_POINTS). I'm sure you could also do this for CS's, and you could also probably separate to have ONLY geometry in curves on the curve layer, not the GEOMETRY points or GEOMETRY CS's as well.
Hope this helps!
Iam not sure why there is a problem for you. I was able to achieve what is being discussed here (if I understood correctly).
I was able to create layers for curves, datum points and sketched points, all with rules and was able to hide all of these independently without overlap.
Iam using Creo 2.0 M180. see attached snapshots for Datum points and Sketched points.
Let me know if I have missing something form the discussion.

It all depends on what is in the "Look for:" field.
If all you want is the curves on the layer - and not the points - then your "Look for:" needs to just be "3D Curve".
If your "Look for:" includes "Feature" then everything owned by the feature that can be hidden will be hidden when the layer is hidden.
The below rule would only collect curve entities owned by any feature type, but not include other entities owned by those features. In other words, the layer rule below would include the curves owned by a sketch, by a curve from x-section, by a curve through points, etc...
You could use the following rule to get all of the points in the model regardless of the feature owning the points. Since the "Look for:" is set to "Point" you will only be getting the point entities themselves and not the features. This would prevent the layer from unintentionally controlling other entities that happen to be owned by the features.
