    Question Visibility relationships between Categories, Subcategories and Nested Categories?

    Hello all, I have a question regarding the way you'd approach visibility relationships between Categories, Subcategories and Nested Categories. I'm trying to accomplish a simple arrangement of these three items for the best possible solution in controlling visibility among objects in their respective views.

    A quick for instance would be a damper that is floor mounted for ductwork. The Family would consist the geometry of the physical damper itself, on the Duct Accessories category. Then, the family would have the structural opening, which would be nothing more than simple linework that is 1/2" greater than the damper LxW, which could be on a Subcategory. In my mind, this approach would be to show the damper itself, and no structural opening, in one view. In a structural framing view, I'd want to show the structural opening subcategory only, and not the damper. But, when you hide the host Category, it hides all the Subcategories. As far as I can tell, if you were to nest another Family, say a Detail Item Family to represent the structural opening, that too will hide if you hide the host Category (Duct Accessory).

    Do I have this correct? If so, what would be some approaches where I can utilize different subcats or nested categories effectively for seamless relationships between different views? I seem to recall - certain Categories anyways - subcategories still being visible (checked) in the view, even if the host category is hidden (unchecked). Maybe this works for some, but not all?

    Thanks in advance!

    In coming back to this, I went with extra subcategories to accomplish what I needed. If anybody still has a better or more clear solution, I'd appreciate it. Thanks!

    Overrides behave differently from visibility on/off, as it pertains to Shared/Nested Families. Thats probably why you think youve seen people "turn off" parent categories, and have the Shared Nested Families stay showing (which you cant do, aside from subcategories. So if you use a filter to shut off the parent family, there is not a way to make the nested family stay visibile).

    A Filter that overrides a Casework family, for instance, does not necessarily override the shared/nested lighting fixture thats within the casework family. But if the filter on the casework family TURNS OFF the casework family, you lose the lighting fixture as well.

    What you want to do can be done with Level of Detail (yuck, lousy solution), or Subcats (mediocre solution), or Filters (if you add in ANOTHER layer of nested objects (Parent object holds two nested objects: The Void-work/line-work component, and the physical object component), and alter the filter to work off of a decent piece of Component Data (or naming strategy). Frankly, while the last solution might feel more "right" i dont know that i would bother doing it. I might roll with subcategories, frankly.

    But (playing devils advocate), if you had 2 nested objects (the hole, and the object itself), it could be one all encompassing filter (only show objects named structural opening, or something), that creates the view without the devices. And that could be really nice.
