Thanks a lot, but i don't want an illustration like a building or a tower, i want to render their real shape, but i don't if i should use some particular color o style for the borders o maybe a texture (like streets) inside it. (still my post about the distance a fluvial boat can reach in a day doesn't show up)
Another big question, any suggestion on the bar that show the scale of the map (like the name of this element could be a good start), i'm now trying to calculate it but i don't know how to draw it.
