## Name

track — Builds a simple representation of the linked track of a vehicle such as a tank.

## Synopsis

`track` [`parameters>`]

## DESCRIPTION

Builds a simple representation of the linked track of a vehicle such as a tank. With no command line arguments, the track command will prompt for all the required input. The vehicle is assumed to be axis-aligned with the front in the +x direction. A combination name for the track is built by appending a unique number to the string track. The information about the track may be included on the command line, and is order-dependent. The parameters are (in order):

- x coordinate of center of frontmost roadwheel.

- x coordinate of center of rearmost roadwheel.

- z coordinate of center of all roadwheels.

- radius of all roadwheels.

- x coordinate of center of drive wheel (rear).

- z coordinate of center of drive wheel (rear).

- radius of drive wheel.

- x coordinate of center of idler wheel (front).

- zcoordinate of center of idler wheel (front).

- radius of idler wheel.

- y coordinate of right side of track.

- y coordinate of left side of track.

- track thickness.

## EXAMPLES

The example shows the use of the track command with arguments to build a simple track.

Example 1. Build a simple track.

`mged>``track 500 0 10 10 -50 50 10 550 50 10 -50 -20 2`

Builds a simple track using the provided arguments.
