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?

I implemented something like this with the ArcSDE 'C' API. There's a couple of issues to track:

Good luck!

PS: In the future, you may want to post this "In a Place" (like Managing Data) instead of relying on it being found in your personal discussion space based on nominal notification and keyword tags. You also might want to add "geodatabase" and "geometry" tags. You can move a discussion/question to a place by clicking on the title, then using the "Move" option off to the right.
