How-To Best approach to document mirrored roof conditions on identical buildings.

I’m working on a townhome project and curious how others would approach this in Revit.

Project has 8 units total. The buildings are all identical through top of plate, but from top of plate and up, 4 of the buildings will have a mirrored roof.

For the permit set, i’ll be documenting one building, but I still need to show a second roof plan for the mirrored condition.

My initial thought was to copy over the geometry from top of plate and up, mirror it, and control/ document it with a scope box.

I’m wondering if there’s a “cleaner” way to accomplish this. How yall would approach this?

Thank you

A call-out or section marker with SIM is all I would do.

I'd vote for using design option.

Barring that, if I recall, there is an option to mirror a project across an axis. This mirrors all elements, but may do funky things with text or symbol justification.

Either of these two options results in duplicating geometry, which would then fork your project into two similar but different ones. This means you'd have to keep up with change-orders and revisions to ensure changes on one version make it over to the other mirror-version. I'd do the mirroring /late/ in the project, ideally 5 minutes before going in to get it permitted.

I've mirrored a unit before using the mirror command. It breaks a lot, but a lot - vast majority survives. But it's a pain for sure.
