ViewSetupHints problem with understanding the documentation

_ViewSetupHints
"This element contains information about the default visibility for elements of certain types (SpacesVisible, SpaceBoundariesVisible and OpeningsVisible) that should be applied if not stated otherwise."_

Another point in the documentation that is not clear and transparent.

What values should I set for these flags when I have IfcOpeningElement or IfcSpace showing enabled in my software? If they are all hidden then false? Should I apply here the optimisation rule only to IfcOpeningElement elements for the situation when most of the IfcOpeningElement is hidden or should I look only at the presence of IfcOpeningElement elements in exceptions and decide on this basis?

The question is also how to read this? If OpeningVisible = true then what should be done? Show all IfcOpeningElement that are in exceptions? What if the default visibility is false then how should the value be for OpeningVisible ?

This is very convoluted and there are no clear rules.

Start with the _ViewSetupHints documentation and its SpacesVisible, SpaceBoundariesVisible, and OpeningsVisible flags. Clarify how each value interacts with IfcOpeningElement, IfcSpace, default visibility, exceptions, and the optimization rule. Done means the documentation states unambiguous rules and examples for these cases.
