Thanks Acetone for the video ,, I did not know how to use that powerful multiselect tool (shift + drag). Now you can have anywhere in the world a design made of well-oriented houses and it would be enough to do this multiselect then ctrl + C press F2 and look for the place of the planet where you want to start working, enter and paste with Ctrl + V and you would have in that new Place all that previous design.I think this can help create cities as long as you just like to recreate reality.
