### Auto Line Construction

The following table indicates the type of line 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. If an incorrect input feature(s) is selected, PC-DMIS will display an error message and will not automatically construct the indicated feature type.

To allow PC-DMIS to automatically determine the best method of construction:

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

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.
