Export LandXML Files (.xml)

Export points, lines, alignments, corridors, surfaces, and a few other miscellaneous data types using the LandXML file format. TBC supports the latest ISO (International Organization for Standardization) standard (ISO 15143-4, 2025). Using this open LandXML schema will improve interoperability within Trimble workflows and compatibility with 3rd-party tools. The new ISO format supports a slightly different set of data types than the previous TBC format (LandXML v1.2 from January 2015), so when exporting you can choose between ISO 15143-4 and the TBC 1.2 formats.

To export LandXML data

Select Export in Home > Data Exchange. The Export dialog displays.
Click the Corridor tab or the Construction tab and then select LandXML exporter in the File Format list.
Click in the Selected entities box. Then, in a graphic view, pick the objects you want to include in the export, or click Options and choose a selection option in the list.
If you want to clip a surface that you are exporting, select a boundary in the Surface clipping boundary list, or select <New> to create one.
Type a path and file name for the exported file in the File Name box, or click the Browse button to browse for a location and specify a file name.
In the Settings group, select export settings.
Click Export.

Exporting Utility Lines/Pipes

When you export a utility network, a custom section called <PipeNetworks> is created in the LandXML file. Utility nodes (fittings, manholes, headwalls, etc.), are listed as <struct> entries. Utility lines (pipes and cables) are listed in a sub-section called <Pipes>. These entries include properties from the Material and Site Improvement Manager definitions for the exported utility site improvement types.

Note: For user-defined utility line shapes, only a bounding box representing the outer extents of the pipe's cross-sectional shape is exported and can be re-imported.
