Hi Angel @Angel90 ,
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..
