How to have different area plans for different phases

[Anonymous]

I need the area plans of the same level of a building during different phases.

It's the same plan, that I have duplicated three times, for three different phases. But when I change the outline of the area plan of one phase, it also changes on the other phase, so I cannot calculate three different area plans.

Thanks in advance
