EDCOMB nged BRL-CAD BRL-CAD User Commands
edcomb Allows the user to modify the attributes of a combination.
`edcomb` combname regionflag regionID airID los% materialID

## DESCRIPTION

Allows the user to modify the attributes of a combination. The combname is the name of the combination to be modified. The regionflag controls whether the combination is identified as a region - supplying either R or 1 for the regionflag indicates that the combination is a region; to indicate the combination is NOT a region simply supply any other character (C or 0 are useful conventions here.) If the region flag is not being set, then the remainder of the attributes are ignored. However, the `edcomb` command requires that something is supplied for those arguments in order to work - so if using `edcomb` to turn off the region flag on a combination simply supply 0 for each of the remaining arguments to `edcomb`. If the region flag is being set, then the region_id, aircode, los, and material_code are set according to the arguments supplied.

## EXAMPLES

The first example shows the use of the `edcomb` command with the R flag (region) added along with the region_id, air_code, los and material_code. The second example shows how to unset the region flag for a particular combination.

Make a combination a region having specific attributes.

mged> `edcomb comb1 R 1001 0 50 8`

  Makes comb1 a region and set its ident to 1001, its air code to 0, its los to 50, and its material code to 8.

Unset a region flag for a particular combination.

mged> `edcomb comb1 C 0 0 0 0`

Unsets the region flag for combination comb1.
