Exercise 3: Adjusting and Verifying Settings

Survey user settings are specific to a Windows user login account and affect only the survey features, and not the database or drawing data.

Survey database settings are specific to the survey features of an AutoCAD Civil 3D survey database.

For more information, see the AutoCAD Civil 3D Help topic Survey Settings.

This exercise continues from Exercise 2: Setting the Equipment and Figure Prefix Databases.
