# SUBSYSTEM OVERVIEW

STEP File Formatter (SAFF) Subsystem

The SAFF subsystem is responsible for formatting the internal working form as a STEP Physical file (Part 21).

# USAGE

The SAFF subsystem has one main interface routine, saff_FormatFile. This routine takes a source model and the name of the STEP Physical file to be created as its arguments. An option value allows the STEP 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 step_InitModelInfo configures the model so that saff_FormatFile is invoked).
