I am trying to adjust my curtain wall. I have 2 sections of CW perpendicular to each other that have a lot of horizontal mullions and hopper windows which are currently all at the correct elevation. Now the floor at the base of my CW has raised 1060 and I need to adjust that base to start at the new level. When I change the base it shifts all the mullions, and windows up, which I do not want. Can someone advise me as to the best way to achieve my goal?

Thanks.

Regards Peter.
