To Export LandXML Data from Land Desktop

Whether you are exporting from Land Desktop or from Autodesk Civil 3D, the process is similar. To export a LandXML file from Land Desktop, click Projects menu Export LandXML. The LandXML Export dialog box is displayed. You can choose to export the point, surface, plot, alignment, and pipe run data from the drawing.

In Autodesk Civil 3D, you can export data to a LandXML file using the ribbon by clicking the Output tab Export To LandXML. You can also right-click an object collection in the Prospector tree and select Export LandXML.

In Autodesk Civil 3D, when you export from the Prospector tree, the Export To LandXML dialog box contains a pre-defined selection set of the data in that collection. When you export uisng the command available from the ribbon, all drawing data is selected by default, and you can adjust the selection by clearing check boxes. Alternately, you can specify the objects to export by selecting them from the drawing.

1. In Land Desktop, either click Projects menu Export LandXML, or enter LandXMLOut at the command line.

   The LandXML Export dialog box is displayed.

   To refine the data selection, use any or all of the Points, Surfaces, Plots, and Alignments buttons. Each of these buttons displays a dialog box in which you can specify data in the project to export.

   To export the selected data, you must select the check boxes next to the buttons. For example, to export pipe runs, select the All Pipe Runs check box. If you clear a check box, then the data is not exported.

   If you choose to export surfaces, plots, or alignments, you can export COGO point references instead of coordinates for the plot and alignment geometry.

2. Under Export Options, click Data to specify the precision settings for the exported data, the imperial unit foot type, the units of exported angles and directions, and whether to export raw descriptions, full descriptions, or both.
3. Under Export Options, click File and specify the reference location for the schema, the default destination location for the exported LandXML file, and whether to export detailed or minimal XML. You can also specify that the exported file is read-only.

   It is recommended to set the coordinate precision to six places when exporting data for data exchange, transfer, or archiving. You can change the coordinate precision in the LandXML Export Data Options dialog box.
