# SUBSYSTEM OVERVIEW

LPIR Interface (LINT) Subsystem

The LPIR subsystem is a low level subsystem in the LINT interface. The LPIR subsytem is responsible for reading an ACIS SAT file or an ACIS BODY into a MDA ACIS model.

# GENERAL CONCEPTS

This substem provides two entry points for the application programmer: lpir_Read and lpir_ProcessBody. The lpir_Read function reads an ACIS SAT file into a MDA ACIS model. The lpir_ProcessBody processes an ACIS BODY that's already in memory into a MDA ACIS model. The entities in the MDA ACIS model can then be mapped to various schemes. Refer to the MAP, LMAP, IMAP and SMAP subsytems on mapping capabilities. The LPIR subsystem can read both solid ACIS bodies and wire ACIS bodies. The subsystem takes as input a function that is called for each step of the processing. This allows the application programmer to do additional processing while reading in each ACIS entity. Additional processing as in attribute handling.

# TOLERANCES

If the application programmer use the lpir_Read entry point, the ACIS modeler's resabs, resnor and resmch is set from the MODEL_SPACE_PNT_TOL value in the MDA ACIS model. Refer the the ACIS Programmer Manual and Application Guide as to the use of resabs, resnor and remch.
