BUILD_REGION(nged)	     BRL-CAD User Commands	    BUILD_REGION(nged)

NAME
       build_region - Builds a region from existing solids that	have
       specifically formatted names based on the provided tags and numbers.

SYNOPSIS
       build_region [-a	region_num] {tag start_num end_num}

DESCRIPTION
       Builds a	region from existing solids that have specifically formatted
       names based on the provided tags	and numbers. The created region	will
       be named	"tag.rx," where	"x" is the first number	(starting from 1) that
       produces	an unused region name. If the -a option	is used, then the
       specified "region_num" will be used for "x." If that region already
       exists, this operation will append the new geometry to the existing
       region definition. If that region does not exist, a new one will	be
       created.	The solids that	will be	involved in this operation are those
       with names of the form "tag.s#" or "tag.s#o@," where "#"	is a number
       between start_num and end_num inclusive,	"o" is either "u," "-,"	or
       "+," and	"@" is any number. The operators and numbers coded into	the
       solid names are used to build the region.

EXAMPLES
       The example demonstrates	how to use the build_region command to build a
       region from existing solids.

       Example 1. Build	a region from existing solids

       mged> buid_region abc 1 2
	   Creates a region named "abc.r1" consisting of:
	       u abc.s1
	       u abc.s2
	       + abc.s2+1
	       - abc.s2-1
	   provided that the above shapes already exist	in the database.
