Export to LandXML (.xml)

LandXML is an open XML file format. The format was principally created by and for the survey, civil engineering, and transportation industries. 

When objects in a model are connected to their respective process codes, you can use this intelligence in the model when exporting to LandXML. For this format, you can set up multiple combinations of 'Code' and 'Description' found in the classifications, so that DWG layer names and LandXML object names are named according to classifications.

1. Follow the general steps in Export to File.

2. Specify options in the LandXML Export Settings.

3. Click OK.

4. Complete additional steps in Export to File.

5. Click Finish.

LandXML-specific Notes

In LandXML exports, you can:

• Add the alignment used for a specific road task (machine control needs the centerline in the same LandXML file as the rest of the road surface layer). This type of export will only export the road task string lines as so-called “irregular lines” to LandXML for use with Leica RoadRunner or import it to Trimble Business Center for further export to Trimble equipment or use the Trimble File Flipper to make machine control files directly.

• Pick just the stringlines you need and push them with topology for use on the total station.

• Join multiple surfaces in task settings, if they have neighboring triangles. See more here. 

To export to IFC file using classifications, see the general export setup for Classifications. The principal solution is the same as shown for LandXML.

1. Enter the file format settings.

2. Select to use Field Codes/Classification.

3. Pick the classifications to use.
