Hello everybody...
I'm trying to find a way to delimit a preservation area within the parcels of my allotment. The area to be preserved has always to be 30% of the parcels area, also it has to be on the bottom side of the parcel. I tryied to had draw it on the pic above.
Is there any transformer that could fill a the polygon within a given percentage, or create another polygon wich the área corresponds to the a percentage of the lot?
