A Ground file can export to Revit by a Land XML file. Then by utilizing the “Site Designer” plugin you can import the Land XML into Revit.
The Site designer plugin can be found and installed through the Autodesk ID account. Under Revit, “Updates & Add on’s”, search “Site Designer”
Once this is installed, a Site Designer plugin will appear in Revit. This will be used to get the LandXML into Revit.
Export the XML file by using the File, Export, Ground, Land XML File. Define the units you would like to use in the export though the Export – Unit Output dialog box.
Inside of Revit, a Site Designer plugin will appear in the ribbon at the top. Select that tab, and select Import Land XML file on the left.
Now the ImportLandXML dialog box will appear.
Select the file to import by using the “…” and choose the positioning system.
