Drawing donuts

Donuts are solid, filled circles or rings created as closed, wide polylines. You can draw a donut using one of several methods. The default method is to specify the inside and outside diameters of the donut, and then specify its center. You can then create multiple copies of the same donut by specifying different center points until you press Enter to complete the command.

To draw a donut

  1. Do one of the following:
    • Choose Insert > Donut.
    • On the Draw 2D toolbar, click the Donut tool ().
    • Type donut, and then press Enter.
  2. Specify the inside diameter of the donut.
  3. Specify the outside diameter of the donut.
  4. Specify the center of the donut.
  5. Specify the center point to draw another donut, or choose Done to complete the command.


Inside diameter (A) and outside diameter (B).

The prompt box provides additional options for drawing donuts. For example, you can specify the width of the donut and two points on the diameter of the donut, or you can specify the width and three points on the donut. You can also draw a donut tangent to existing entities.

TIP A donut can be a completely filled circle by specifying an inside diameter of zero.
