COMGEOM-G(1)			    BRL-CAD			  COMGEOM-G(1)

NAME
       comgeom-g - convert GIFT	COMGEOM	model into MGED	database

SYNOPSIS
       comgeom-g [-d debug_lvl]	[-v version_num] [-s name_suffix] file.cg
		 file.g

DESCRIPTION
       Read a COMGEOM version 4	or version 5 format model from a GIFT-style
       input file, convert the geometry	into the internal form used by the
       BRL-CAD package,	and write an MGED-style	binary database.

       Each solid is given the name s###, retaining the	COMGEOM	solid number.
       Each region is given the	name r###, retaining the COMGEOM region
       number. Regions are grouped together into various groups	g### based on
       the region-id numbers. Group g00	gets all regions with region-id	of
       zero, g0	gets ids one through 99, g1 gets ids 100 through 199, etc.

       The default input is COMGEOM version 5. Version 4 can be	converted by
       specifying the -v4 flag.	For the	time being, the	DoE MORSE/RAFFLE
       format (believed	to be the original MAGIC format) can be	converted by
       specifying the -v1 flag.

       By default, the program comgeom-g operates silently. Because the
       program may require a minute or two to convert a	large database,	some
       users prefer to have various status reports that	indicate the progress
       of the conversion. This can be selected by specifying the -d1 flag
       (debug level 1).

       In the resulting	.g file, high-level group all.g	is created. If the -s
       option is used, its argument (without automatic supplying of leading
       period) is tacked onto the end of the names of all other	items in the
       .g file.

       The units used in a COMGEOM file	are specified on a header record. The
       units of	an MGED	database are always millimeters.  comgeom-g performs
       automatic units conversion using	the built-in units conversion feature
       of libwdb(3).

EXAMPLE
       comgeom-g -d1 -v4 file.cg file.g

DIAGNOSTICS
       The diagnostics are intended to be self-explanatory. Familiarity	with
       GIFT COMGEOM terminology	will be	helpful.

BUGS
       It is expected that the input file should be a valid COMGEOM model.
       While quite a bit of input checking is performed, wildly	incorrect
       input may produce amusing results.
