conceptually this doesn't seem hard, but i can't figure out how to do the following:
i have 700 building footprints. i am trying to show what it would look like if 35% (or $40% or 70% etc) of each building footprint had a green roof on it. i did some research and tried using a parcel fabric. that didn't work because while it did allow me to split the buildings into equal parts, i couldn't specify a percentage. also, you had to split each footprint individually - i am looking for something that will allow me to do it all at once. next i though about using an interior buffer. if i can calculate the distance of a buffer to "eliminate" 65% of a building footprint (so that 35% remains) that could work. however, i am not a math/geometry wiz - how would one go about calculating the distance of a buffer as i described above? baring that, is there another approach i am missing?
