.SH "NAME"
arb \- Creates a new ARB shape with the specified \fIarb_name\fR\&.
.SH "SYNOPSIS"
.HP \w'\fBarb\fR\ 'u
\fBarb\fR {\fIarb_name\fR>} {\fIrotation\fR} {\fIfallback\fR}
.SH "DESCRIPTION"
.PP
The
\fBarb\fR
command creates a new ARB shape with the specified
\fIarb_name\fR\&. 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
\fBae\fR
command\&.
.SH "EXAMPLES"
.PP
The first example shows the use of the
\fBarb\fR
command to create a new ARB shape with a specified name\&. The second example shows the use of the
\fBae\fR
command to determine the view orientation of the arb\&.
.PP
\fBExample\ \&1.\ \&Create \fInew_arb\fR with a specific rotation angle and fallback angle.\fR
.PP

mged>\fBarb new_arb 35 25\fR
.PP
Create new_arb with a rotation angle of 35\(de and a fallback angle of 25\(de\&.
.PP
\fBExample\ \&2.\ \&Using the ae command to determine the view orientation of the arb\fR
.PP

mged>\fBae 35 25\fR
.PP
Rotates view to look straight on at square face of
\fInew_arb\fR\&.
