# SUBSYSTEM OVERVIEW

IGES ASCII File Formatter (IAFF) Subsystem

The IAFF subsystem is responsible for formatting the internal working form as an ASCII IGES data file.

# USAGE

The IAFF subsystem has one main interface routine, iaff_FormatFile. This routine takes a source model and the name of the IGES file to be created as its arguments. An option value allows the IGES file to be overwritten if it already exists. Normally the formatter is invoked by calling mda_FormatFile with any options to be passed to iaff_FormatFile (the routine iges_InitModelInfo configures the model so that iaff_FormatFile is invoked).
