I have to mirror houses all the time for a tract builder. Here's my method:
1. Save all elevations sections & details as modules
2. Open one worksheet for every elevation, section & detail & name it appropriately. Place the modules in each worksheet use the reverse check box.
3. Save the worksheet as a view.
4. Save the entire plan with a different name. Open it and bold marquis with all layers and renovation status on / showing (I use reno status for options and alternates). Delete.
5. Place a module linking the original plan with the reverse check box to the new one and save.
6. In the original plan add the worksheet views to the layouts as if they were views of the main model.
7. Place external drawings from the new plan to the plan layouts.
This produces an exact mirrored copy. Labels, text, dimensions etc mirror correctly. In the past I had trouble with area fill labels mirroring incorrectly but that seems to have been fixed.
Continue to work in the original plan for any changes or revisions, save and update the reversed plan. The update all layouts.
While this may seem time consuming (about an hour for me now I know what I'm doing) once it is set up, updates and revisions are a breeze.
