How do you change the overall project elevation? My revit model is already built, but I need this entire model to be lowered to a new elevation. 

See attachment.

I thought my first post didn't go through so I re-posted it.

It was a mistake 🙂 

I solve the problem using your advice! Thank you so much again!
