Am trying to build barns with basements (quite common in NE US of A, and so far no go. Not the basemen as such, but the sloping sides of the excavation. None of the standard issue tools enable either a vertical land cut or a means to connect the barn to the terrain outside. Yes, I could put the barns on regular foundations, but the overhanging provision for floor tiles prevents making a ramp to gain access. Connecting stairs may work for sims, but not wagons, cows, etc. All help gratefully accepted.
