Application menu Export [Files of type]=OpenFlight (*.FLT)

There are two ways to export your scene to an OpenFlight file.

The default method is to choose Export from the 3ds Max Application menu. The steps are described in the procedure that follows.

You can also choose File Export Selected. Use this if you want to export only selected objects from your 3ds Max scene to the OpenFlight format.

Procedure

To export a scene to an OpenFlight file:

  1. In 3ds Max, choose Application menu Export.
  2. In the Export dialog, use the Files Of Type drop-down menu to change the file type to OpenFlight (*.FLT).

  3. Type in the name of the file you want to export, then click Save.

Interface

Version

This drop-down list sets the version of OpenFlight that the model will be exported to. You can export to versions 14.2 through 15.8. The list shows all possible options.

Real World Location group

Projection

This drop-down list chooses the cartographic projection of the coordinate system. You can choose from Flat Earth, Trapezoidal, Round Earth, Lambert Conic, UTM, Geocentric, and Geodetic projection methods. Default = Flat Earth.

Ellipsoid

This drop-down list defines the ellipsoid (also known as "the Datum") of the coordinate system. You can choose from WGS 1984, WGS 1972, Bessel, Clarke 1866, and NAD 1927. Default = WGS 1984.

Units

This drop-down list chooses the units of measure of the coordinate system for the exported model. You can choose from Meters, Kilometers, Feet, Inches, or Nautical Miles. Be aware that Kilometers and Nautical Mildes are not 3ds Max units. This field setting will be written to the header node of the OpenFlight file. Default=Meters.

Origin

These fields set the latitude and longitude of the origin of the database.

Lambert Upper

This field sets the latitude of the upper Lambert parallel. This field is active and available only when the Projection method is set to Lambert Conic.

Lambert Lower

This field sets the latitude of the lower Lambert parallel. This field is active and available only when the Projection method is set to Lambert Conic.

Options group

Auto Group

When off, the OpenFlight exporter will create an OpenFlight Group only when there is a 3ds Max group object. 3ds Max objects that are children of other 3ds Max objects will be siblings in the OpenFlight hierarchy. When on, an OpenFlight group will be created whenever a 3ds Max object is the child of another 3ds Max object. Default=on.

Auto Object

When off, a 3ds Max object that is composed of multiple polygons will have only the polygons exported. When on, a 3ds Max object that is composed of multiple polygons will be placed under a common OpenFlight Object record. Default=on.

Copy Textures to Output Directory

If the OpenFlight file is exported to a different directory, then when this option is on, any textures will be copied to the same destination directory. When off, the textures are not copied. Default=on.
