                               that are not at the current version of NX.
  -f                           Used with the -y switch to force all components
                               to be processed.
  -us                          Updates the assembly structure to include
                               any changes in lower level sub-assemblies.

  -convert_mcs <filename>      Converts mating conditions to assembly
                               constraints. Logs a constraint conversion
                               report to <filename>.
     -mc_parts_only                      Used in conjunction with convert_mcs
                                         to specify only parts which
                                         contain mating conditions.
     -mc_dry_run                         Used in conjunction with convert_mcs
                                         to do the mating condition conversion
                                         and generate the conversion report
                                         without saving any parts.
     -mc_dont_load_referenced_geometry   Used in conjunction with convert_mcs
                                         to not load geometry referenced
                                         by the mating conditions being
                                         converted. Note this will bypass
                                         constraint conversion checking.
  -regen_lw                    Force all lightweight bodies in the specified
                               part to be regenerated. The faceting parameters
                               previously used to create each body will be
                               used again. Note: For assembly level
                               representations the regeneration operation
                               will be executed only if the source component
                               parts are loaded. The -y switch can be used to
                               ensure the components are loaded. This option is now
                               done by default for parts saved prior to NX7.5.
  -regen_lw_def_tol            Same as -regen_lw except that with this option
                               the faceting parameters on the existing body
                               will be ignored and the default system or user
                               specified (if defined in the customer defaults)
                               faceting parameters will be utilized.
  -convert_line_widths         Converts all legacy line width in the specified parts
                               to use new line widths. Conversion is done based on 
                               the Legacy Line Width Conversion part preference.
  -create_drawing_snapshot     Creates snapshot data of the part for its drawings.
  -recreate_missing_stock_components For Routing assemblies this option will re-create
                                     any missing stock as component components.
