So basically the title says it, i have this -> 
(top view), but i'd like to make them actual sharp edges, how could i do this? i suspect something to do with the "resample curve" there was to make it fit, thanks in advance.
Hi Angel AAngel90 ,
That's probably not going to be easy with this setup. The Resample Curve is not where you can do something to that effect (I think).
You'd have to make certain that both the length and the width of the building cutouts are divisible by 3, which should be done aroung here:

But I don't know how to do that, because those are (amongst others) dependent on the road (and sidewalk,...) sizes..
