LandXML provides a non-proprietary data standard that is driven by an industry consortium of partners.
Use LandXML to transfer data to another drawing or to another application that supports imported XML. For example, you can use LandXML to transfer surfaces between drawings.
Many AutoCAD Civil 3D objects are supported for LandXML import and export. See Supported LandXML Data for Drawing Import and Exportfor a list of supported objects.
In addition, Survey database data can be imported and exported. For more information, see Importing Survey XML Data.
By transforming AutoCAD Civil 3D drawing data to LandXML, you can:
- Exchange data. Import LandXML data into other software applications. The data can then be modified and delivered to customers and agencies in the required formats.
- Transfer or archive data. Transfer data to another AutoCAD Civil 3D drawing. Also, you can archive data in a non-proprietary format.
- Convert units. Export data using imperial measurements. Then, import it using metric to scale and convert values.
- Translate/rotate coordinates. Globally adjust the elevations of data.

- Supported LandXML Data for Drawing Import and Export
LandXML supports AutoCAD Civil 3D drawing data for import and export.
- LandXML and Sites
In an AutoCAD Civil 3D drawing, a site is used to collect or group sub-collections, such as parcels, alignments, and gradings, by a topology that they share.
- Handling Duplicate LandXML Data on Import
When objects in the drawing have identical names to objects in a LandXML file, the imported data can be skipped, renamed upon import, or it can overwrite the existing data.
