In AutoCAD Civil 3D, survey data is not drawing dependent and is stored in an external database. For display and visualization, survey data can be manually and automatically inserted into a drawing when the survey database is updated or when data is imported into the survey database.
The Survey database consists of two files, the.sdbx file is the main survey database and it contains all the data in the survey database collections except for the Extended Properties definitions and values. The Survey .sdxx file contains the Extended Properties definitions and values.
To support a 64-bit operating system in AutoCAD Civil 3D 2011, survey database files, equipment database files, and figure prefix database files must be migrated to a new format. On the Survey tab in Toolspace, a database item that requires migration will display the "out-of-date" icon to provide a visual cue that it requires migration. To complete the migration, right-click the item and select the migration command.
Tutorial Exercise: Setting Up the Database and Drawing
Topics in this section
- Survey Database
Use the Toolspace Survey tab to create local survey databases. You can subsequently create a new AutoCAD Civil 3D Project from the existing local survey database.
- Survey Database Change Report
Use the Survey Change Reporting feature to report any changes that are made to a survey database.
- Survey Equipment Database
The survey equipment database contains one or more equipment definitions.
- Survey Figure Prefix Database
The survey figure prefix database contains information to determine the layer that a figure is drawn on, how a figure is stylized, and whether figures are created as breaklines and lot lines.
