Randomly place array within curve, no overlap

Hello all,

Im translating an array of boxes to a random point populated within a curve. Then the array of boxes is rotated randomly aswell. BUT i can't manage to find how I should solve the problem of the array overlapping the curve, which represents the boundary of a building plot. I want the script to check whether the building is inside the curve, if not rotate it more so it is or determine that that is not possible and don;t display the option.

Script added, bit messy sorry
