• Files collapses each file into one node

• Layers collapses each layer into one node

4. Limit number of Polygons should be enabled 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. View, Scene Statistics in JetStream 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.

Note

Google Earth's ability to handle large numbers of polygons is far more limited than JetStream.

Hence it is worth noting that currently Google Earth will consider 1,000,000 polygons as being a

big model.

5. The Origin position values are the first pair of reference points on the Google Earth surface, and

must always be defined. The JetStream 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 main 3D view.

These points must be visible in the main 3D view prior to exporting, as once the KML Options dialog

is open you will not be able to navigate before picking.

Note

You may wish to use View, Split to split the main 3D view enabling you to have separate views of

each reference point.

6.23. Quitting JetStream

Quitting JetStream

1. Go to File, Exit

2. If the model has been changed since opening it, JetStream will ask you whether you want to save

any changes. Respond appropriately and JetStream will then close.
