# To export LandXML string roads from Trimble Business Center

For best results when using LandXML string roads in the Trimble Access Roads software, export files using Trimble Business Center version 5.80 or later.

You can export a LandXML string road from Trimble Business Center as:

- An alignment and associated corridor.

- An alignment and associated road surface model, where the breaklines define the road strings.

For either method you can also include point and non-road surfaces in the export.

To export the road as an alignment and associated corridor

1. Start Trimble Business Center and select a project.
2. Open the Project explorer in Trimble Business Center and select the alignment and the associated corridor you want to export. To export more than one road, select each alignment and the associated corridor that makes up the road. The selected alignments and corridors are highlighted.
3. From the Home ribbon, select Export.
4. From the Corridor tab, select LandXML exporter.
5. If required, select the points and non-road surfaces to export.

6. From the Settings / Surface description field, select:

   - 1 - Points and breaklines to ensure the road strings are created.

   - Both 1 and 2 to include additional surfaces, for example additional subgrade or embankment.

   If you are exporting multiple surfaces in one file, then you need to make sure the appropriate horizontal alignment is specified in the surfaces.

   To do this, open the Project explorer in Trimble Business Center, expand Surfaces and right-click the surface and select Properties. Scroll to the Surface group and make sure the Horizontal alignment field shows the horizontal alignment you wish to use. If required, select the preferred horizontal alignment.

7. Select Export to export the file.

To export the road as an alignment and associated road surface model

1. Start Trimble Business Center and select a project.

2. In the map or the Project explorer in Trimble Business Center, hold down the CTRL key and select the horizontal alignment and the surface.

3. If there is only one vertical alignment associated with the selected horizontal alignment then the vertical alignment is automatically selected and will be exported.

   If there is more than one vertical alignment associated with the horizontal alignment, then do one of the following:

   - Make sure the vertical alignment you want to export is specified as the active vertical alignment. To do this:

     Open the Project explorer in Trimble Business Center, right-click the horizontal alignment and select Properties. Scroll to the Other group and make sure the Active vertical field shows the vertical alignment you wish to use. If required, select the preferred vertical alignment.

   - Select the vertical alignment to export. To do this:
