Isometric Reverse - Invert Routine Needed

[RocksterB]

I need a routine that will take existing isometric elements and create a reverse/inversion of those entities. For example, using the available isometric door elevation entities in a 30 degree, SW view, with the door knob &  on the left and hinges on the right, the routine creates a copy of the door and converts them into a 30 degree, SW view door, with the door knob on the right, hinges on the left. So it’s not a mirror of the entities, but more of a reversal of the entities. I know the new isometric elevations won't be perfect, but it creates a great starting point to modify.

Put "isometric mirror" or "mirror isometric" into the Search window -- lots of threads that look like they're asking exactly the same thing, so if there's a solution, it should be in one or more of them.
