Envelope Types

Rear Tires

Select this check box to have the movement drawn with envelopes that trace the outside edges of the vehicle’s rear most axle group.

The envelopes generated depend upon the composition of the rear axle group:

• If the group contains fewer than three fixed axles: one envelope is drawn for the center of the group.
• If the group contains more than three fixed axles: one envelope is drawn for the center of the group and one for the last axle.
• If the group contains all steerable axles: one envelope is drawn for the first and last axles.
• If the group contains a combination of fixed and steerable axles: one envelope is drawn to trace the center of the fixed group and either the first axle (if there are more steerable axles in front of the fixed group) or the last axle (if there are more steerable axles behind the fixed group).
