The DefaultTrack3d command is used to set default 3D Graphics attributes for all new tracks within a Multi-Track Object (MTO).

{TrackOptions} Description
Show {On | Off} Indicates whether to show 3d graphics for the track.

LabelOffsetInPixels {On | Off} Enable to define the offset by pixel values instead of the default (Cartesian).
LabelOffset <X> <Y> [<Z>] Defines the position of the track label relative to the track. If the label offset is defined by Cartesian values, then <Z> is required and <X> <Y> and <Z> values are input in meters.
ZAxisTowardsNadir {On | Off} Enable to orient the model as an aircraft, or disable to orient the model as a surface vehicle.
DefaultAzimuth [Angle <Angle>] [UseOnLast {On | Off}] Specify the initial bearing of the model, relative to north.

If this option is set to DefaultFromMarker, then the default color is the same as the marker color. Note: This option will only affect colorless models.
ScaleModel <ScaleFactor> Defines the absolute scale factor.
ScaleLog <ScaleFactor> Defines the model scale exponentially.
Marker {Options} Refer to the VO Marker command.
