Plan regions to have their own model category selections. - Plan region is not affecting display of MEP elements (duct, pipe, conduit) in Revit

[scott.r.kennedy]

Please make all MEP elements visible in plan regions when adjusting View Range. It is illogical that certain categories do not display. Alternatively, add a feature such that Plan regions can have their own model category selections independent of the View settings.

This is driving me nuts. Its been known about since 2025. 

Please fix / prioritize for next Revit release.

Thanks.

@kimberly_fuhrman-jones would it make sense to combine this one with https://forums.autodesk.com/t5/revit-ideas/support-of-mep-elements-pipe-cable-trays-in-plan-regions-...?

Sort of, but its more than that. What I am suggesting is have a model category selection assigned to Plan Regions, so we can remove unwanted categories from showing. Super useful.
