Here is a great tool but seldom used... for good reason, not too
often you have to totally flip your design.
The Mirror tool is located under the Manage Tab on the Project
Location Panel (version 2012 and
2013).
You get the option to mirror along a number of different axis but
you cannot pick a custom axis line.
Works great however I did get a couple error messages asking me to Review elements for correct Position and
shape, Unjoin one wall from floor and a dimension that had to be deleted as
the references had become invalid.
Still these are pretty minor in my opinion.
All in all the results are pretty good.
Now I just have to wrap my head around this new flipped design!!
