My upper level city design is progressing. Now I know why I am not a city planner.
The City Model is in CorelDraw. The drawing is done in actual size of the 1/4 scale city. Once compete I will use it to make Laser Cuts of the streets and sidewalks then reassemble in to the whole city.
The Woodland and Menards buildings, cars and sewer grates provide guides and orientation to making and cutting the streets and sidewalks.
