6 Specify points within each area that you want to form a boundary
polyline.
This area must be totally enclosed; that is, there can be no gaps between
enclosing objects. You can select more than one area.
7 Press
ENTER to create the boundary polyline and end the command.
AutoCAD creates a polyline in the shape of the boundary. Because this
polyline overlaps the objects used to create it, it may not be visible. How-
ever, you can move, copy, or modify it just as you can any other polyline.

Draw Donuts
Donuts are filled rings or solid-filled circles that actually are closed polylines
with width.
To create a donut, you specify its inside and outside diameters and its center.
You can continue creating multiple copies with the same diameter by
specifying different center points. To create solid-filled circles, specify an
inside diameter of 0.
To create a donut
1 From the Draw menu, choose Donut.
2 Specify the inside diameter (1).
3 Specify the outside diameter (2).
4 Specify the center of the donut (3).
5 Specify the center point for another donut, or press
ENTER to complete the
command.
