Creating an outline of an object that is a certain distance away from all points
Hello everyone,
I am trying to put together a map that outlines 500ft (1in = 50 ft) from a proposed premise. Does anyone know how I can create an outline of a shape that is exactly 10 inches away from all points of the proposed shape? Please find below an image of what I am trying to do. There are two outlines in the image below. Any help would be greatly appreciated.
