Thanks Paul!!!

I tried to do what you kindly suggested.

Many of the buildings here have angles that are not at 90° because of the ditch.

If you have time, please check it again.

In the next few days I will try to separate the parking lot from the building. There is more or less 5 meters of distance between the two

Many Thanks Again! Grazie Mille!
Have a Nice Day!
