reply to daluigi: -It depends on the Options that the person running the Refile adds to the command line. One can for example have the refile function update drawing views.
Open a NX command prompt ( then all env variables are in place)
Cd into the NX install directory , ( i.e C:\siemens\NX7.5\ugii\)
type "refile_part.exe" and press enter, then the options will be listed.
While Mark is ostensibly correct, there are some additional things that can be done with 'refile_part' that does not happen when you open a legacy part in a newer version and then hit the Save button. This is particularly true when upgrading from anything older than NX 7.5 to NX 7.5 or NX 8.0.
In this case, there are some additional options with respect to how the lightweight faceted representations are updated. If you simply open an existing legacy part and save it, if there already was a lightweight representation it will be recomputed using the tolerances referenced in the model. However, by pre-setting the Customer Default to what you would like the global lightweight tolerance to be and then running 'refile_part' using the correct option, this will force a complete recreation of the lightweight representations taking into account whatever lightweight options you has set in Customer Defaults. In fact, if you ARE indeed upgrading legacy parts from before NX 7.5 YOU MUST USE ONE OF THE LIGHTWEIGHT OPTIONS in order to get part files which can take full advantage of the new lightweight behavior was well as getting the best results when creating Drawings of Assemblies.
And while, as Toost suggested, you can get the listing of the options by just running 'refile_part' with no options set, it might be easier to just go to your NX Help files and search on "Running refile_part". Here you will find a complete list of all of the option codes as well as explanations as to what each one does. Based on what I stated above and what you will see if you do this documentation search, we recommend that use the -regen_lw_def_tol option, in combination with setting the proper options in Customer Defaults, to get the best results.
