About LandXML Import and Export

Use the AutoCAD Civil 3D LandXML import and export commands to import and export drawing data in LandXML format.

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.

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.

Many AutoCAD Civil 3D objects are supported for LandXML import and export. In addition, Survey database data can be imported and exported.

The LandXML import and export functionality is based on the LandXML schema. AutoCAD Civil 3D supports the following LandXML schema versions:

• LandXML-1.0
• LandXML-1.1
• LandXML-1.2

LandXML provides a non-proprietary data standard that is driven by an industry consortium of partners. For more information about the LandXML schema, go to www.landxml.org.
