Mirroring A Plan View In Revit

I use the Orient to View option on the View Cube frequently, always looking for new ways to exploit it.  Recently was a first for a customer request.  This customer is not only design, but also fabrication-based, and required drawings of their Revit models that were viewed from below.  Not a Reflected Ceiling Plan, but actually a worm’s eye, orthographic plan at the cut plane, editable and dynamic.  The best answer I could come up with was using the Orient to View option.

I start by duplicating the floor plan and renaming it for the Orient to View resource.  Change the View Range settings as needed, i.e., Cut plane and Bottom values at 7′-0″ for this customer.  Create a new 3D default view and then using the right-click option, orient the 3D view to the duplicated floor plan; the Section Box will respect the View Range settings for Top and Bottom.  Then manipulate the edges of the Section Box as needed for the x and y axes.  Hide the Section Box object when no longer needed if desired.  Again, for this customer, a mirrored floor plan about the y-axis was needed, so selecting the bottom of the View Cube and rotating about the z-axis brings us to the upside-down plan view.  Now the best part.

The shop drawing required dimensions, so we can now lock the 3D view’s orientation, copy the dimensions from the floor plan to clipboard, and paste to the same place in the re-oriented 3D view.  They will find their hosts and show changes if the normal floor plan is edited, making the display dynamic.  Not all annotations will follow suit, but some tags, if needed and they find their hosts in the view, will paste into the re-oriented 3D view.
