Flip A Plan, All Type Is Forever Upside Down.

[Doug-o]

If a plan is flipped vertically, all the type is forever upside down and the x-y co-ordinates are reversed.  I realize it is much more common to flip a plan horizontally, but the x-y's will still be reversed in this case also.  What is up with that?

Doug-o,

 

It sounds like you used Rotate Plan View to flip your plan. 

 

I would strongly advise against ever using this tool unless you know exactly what you are doing.

 

It doesn't just rotate the plan on the screen, it actually rotates the "drawing board", including the coordinate system and other things - as you have discovered.

 

It's as if you rotated your whole drawing board 180deg and now need to draw upside down.

 

I think this is a good case for one of Lew's locks - Rotate Plan View lock or a warning asking if you really know what you are doing.

 

Better to use another method to rotate your plan.
