WHICHAIR

## Name

whichair — Reports information relating to usag of air codes on regions.

## Synopsis

`whichair` [`options ...`] {`air_codes`}

## DESCRIPTION

Reports information about the usage of the air_codes property by regions in a .g file. Its default mode is to report which regions in a .g file are using one or a range of region_id values. If a root object is specified, it will report that result only for the regions in the tree of the root object. If the `U` is specified, the reporting is inverted and the command will report the ranges of unused aircodes rather than the regions using various aircodes.

The eac command will perform a similar search, but will draw the qualifying regions in the MGED display rather than listing them.

## OPTIONS

-U

  Report unused aircode ranges.

--root objname

  Limit reporting to regions in the CSG tree below objname.

## EXAMPLES

For these examples the geometry file used is the standard m35.g included with BRL-CAD.

Example 1. Report all regions using air codes between 7 and 10.

`mged>``whichair 7-10`

Region[s] with air code 7:
r11
r13
r15
Region[s] with air code 8:
r25
r27
r29
r31
r33
r35

Example 2. Report all unused aircode ranges in the database between 1 and 10.

`mged>``whichair -U 1-10`

Unused air codes:
1-3
5
9-10
