### Auto Circle Construction

The following table indicates the type of circle that will be constructed when the specified inputs are selected and the AUTO option is chosen. The order of the selected features is not important.

1. Access the Construct Circle dialog box (Insert | Feature | Constructed | Circle).

2. Select the Auto option from the list of options.

3. Select the desired feature(s) based on the table below.

4. Click the Create button.
