How to get space planning possibilities from project refinery from an existing floor plan

Hello, I am very new to dynamo. I have a floor plan of a school and I would like to check the different options of space planning using generative design in project refinery. Any idea how to do this? I have seen numerous tutorial but couldnt do it. Thanks.

@azra.malihaVFKXP, i am also trying to do something like this, but all the tutorials i have seem so far are to get design options from scratch. possible to share the tutorials you watched?
