G-STEP(1)			    BRL-CAD			     G-STEP(1)

NAME
       g-step -	STEP Translator/Exporter (BRL-CAD to STEP AP203)

SYNOPSIS
       g-step -o output_file.stp database.g [object(s)]

DESCRIPTION
       g-step converts the specified objects of	the BRL-CAD database,
       database.g, to a	STEP AP203 file, output_file.stp.

       The following options are recognized.

       -o output_file_or_directory
	   Specifies the output	file to	which the STEP output is written.

       There are some inherent limits when writing BRL-CAD geometry to the
       AP203 format. The primary solid object representation used by STEP is
       the NURBS Boundary Representation, and BRL-CAD's	CSG models must	be
       converted to that representation	upon export. Boolean operations	are
       not supported in	AP203, so the objects are either to write out all
       objects and post-process	them in	another	system to get the final	forms
       or have BRL-CAD itself perform the boolean evaluation at	the region
       level. The latter will eventually be the	default, but for the moment
       that feature is not yet ready for general deployment.

EXAMPLES
       Example 1. Export All .g	File Contents

       g-step -o m35.stp m35.g

       Writes out the full hierarchy of	the .g file to m35.stp .

       Example 2. Export Parts of a .g File

       g-step -o m35.stp m35.g cab suspension

       Writes out the hierarchies associated with the combs cab	and
       suspension, along with all combs	and solids needed to define those
       hierarchies.
