I'm a little confused by the width parameter on the Pie function. I put in a .2 mile radius pie and got what I expected. When I changed the width, the maximum distance of the draw object from the center seemed to increase from .2 miles, maybe using the radius as the center of the newly created annulus. Is this right? Would it be better to leave the radius as the max radius and use (radius-width) to give the new minimum radius?
