4 Select the Enable check box in the Limit Number of Polygons area to restrict the amount of geometry
exported into the output file. Geometry is selected on the basis of taking the most obvious objects in
preference to the fine detail. If the exported file is too large for Google Earth to display, try enabling this
and reducing the number of polygons. Clicking the Home tab, sliding out the Project tab, and clicking Scene
Statistics
in Autodesk Navisworks shows the number of triangles and/or lines in the current project. By
setting a polygon limit you are choosing to export only some of these items.
5 The Origin position values are the first pair of reference points on the Google Earth surface, and must always
be defined. The Autodesk Navisworks reference point will always be positioned to exactly overlay the Google
Earth reference point.
Second and Third reference points can be used, and if enabled then the position and orientation of the
model can be more accurately defined.
6 Use the Import buttons to read-in saved placemark locations from KML files exported from Google Earth.
The Origin Import button differs slightly from the other two; if the KML file contains multiple placemarks,
this button will offer the user the choice of importing second and third reference points if available. The
other two buttons will only import a single reference point.
7 The Pick buttons allow the reference point locations to be selected in the Scene View.
These points must be visible in the Scene View prior to exporting, as once the KML Options dialog box is
open you will not be able to navigate before picking.
TIP You can click View tab ➤ Scene View panel ➤ Split View drop-down, and select Split Vertical or Split
Horizontal to split the Scene View into separate views of each reference point.
8 Click OK.
9 In the Export dialog box, enter a new filename and location, if you want to change from those suggested.
10 Click Save.
Autodesk FBX Format
FBX files can be exported from Autodesk Navisworks. The exporter creates an FBX file with the extension .fbx
and supports the export of:
■ Triangles
■ Lines
■ Materials (color, flat transparency, and wrapped image texture only)
■ Viewpoints
■ Lights
■ Model Hierarchy
To export an FBX file
1 In Autodesk Navisworks application, click Output tab ➤ Export Scene panel ➤ FBX
.
2 In the FBX Options dialog box, select the Enable check box in the Polygon Limiting area to restrict the
amount of geometry exported into the output file.
Geometry is selected on the basis of taking the most obvious objects in preference to the fine detail. If the
exported file is too large, try enabling this feature and reducing the number of polygons. Clicking the Home
