## Name

arb — Creates a new ARB shape with the specified arb_name.

## Synopsis

`arb` { `arb_name`>} { `rotation`} { `fallback`}

## DESCRIPTION

The arb command creates a new ARB shape with the specified arb_name. The new ARB will be 20 inches by 20 inches and 2 inches thick. The square faces will be perpendicular to the direction defined by the rotation and fallback angles. This direction can be determined by interpreting the rotation angle as an azimuth and the fallback angle as an elevation as in the ae command.

## EXAMPLES

The first example shows the use of the arb command to create a new ARB shape with a specified name. The second example shows the use of the ae command to determine the view orientation of the arb.

Example 1. Create new_arb with a specific rotation angle and fallback angle.

`mged>` `arb new_arb 35 25`

Create new_arb with a rotation angle of 35° and a fallback angle of 25°.

Example 2. Using the ae command to determine the view orientation of the arb

`mged>` `ae 35 25`

Rotates view to look straight on at square face of new_arb.
