ALIGN DIVISION OF DIFFERENT SURFACES

Hi Everyone,

I'm trying to do a kind of brise soleil but I need it to be aligned on all floors.I'm using diva to calculate de radiation and then I use the number to control the size of the panels. I'm appling it for each surface of each floor. The problem is that as the closing of each facade is different, the division will be different too. So what ca

n I do to align it? Thanks =D
