Just draw a road and it happens. From a path to a super freeway. If the road goes beyond the (15?) degree slope that a real road goes then give an option to build a tunnel or make a bridge or do nothing but build the an extreme road. Draw in rivers the same way. Paint in different textures on land. Put in your own increment for the nudge, like in Illustrator. Mathamatical operators for variables. If you want to change the X,Y,Z variable you could put in X*3 or X/2 or X-2 or X+5 or X=y. Like in Illustrator. When an object is expanded it grows from the center. I would like to be able hold down some key and the opposite corner is locked down so only one side goes out.
