Google Earth KML Format
Google Earth KML files can be exported from Autodesk Navisworks. The exporter creates a compressed KML file
with the extension .kmz and supports the export of:
■ Triangles
■ Lines
■ Materials (color and flat transparency only)
■ Viewpoints (adjustments may occur due to Google Earth limitations)
■ Model Hierarchy
■ Hyperlinks (currently only URLs work correctly in Google Earth)
To export to Google Earth KML files
1 Click Output tab ➤ Export Scene panel ➤ Google Earth KML
.
2 In the KML Options dialog box, select the Export Model Relative to Terrain Height check box to put Google
Earth in a mode where all heights are measured from the surface of the ground. When this is check box is
clear all heights are measured from sea-level.
NOTE When positioning a model relative to sea level, the height of the Google Earth reference points must also
be measured relative to sea level. When positioning a model relative to the ground, the Google Earth reference
points must be measured relative to the ground.
Google Earth always places new placemarks at an altitude of zero, irrespective of whether that is relative or
absolute.
3 The Collapse on Export drop-down list allows different levels of collapsing parts of the model hierarchy in
the exported file. Choose from:
■ None - ensures the whole hierarchy is exported
■ All Objects - collapses everything into one node
■ Files - collapses each file into one node
