For the future - use the search function in the forum...
From ewh (thanks)
I got this directly from "Gateway". You must open a command prompt window (PROGRAM-UNIGRAPHICS-UNIGRAPHICS TOOLS-COMMAND PROMPT).
At the operating system prompt, type:
ug_convert_part -mm|-in -[o s u uo x y] [-o <dirname>] <part_name>|-d <dirname>
Options in brackets are not required. Options separated by the pipe character `|' mean that you must provide either the option before the pipe or the option after the pipe, but not both. The first set of options, -mm | -in, denotes the units you are converting to, and are not optional. You must either use -mm to convert to millimeters or -in to convert to inches.
d
Sets current directory as the source
-d <dirname>
Sets the directory <dirname> as the source
-in
Converts to inch units
-mm
Converts to metric units
-o <dirname>
Sets the directory <dirname> as the destination
-s
Traverses subdirectories
-u
Converts UDFs (user defined features)
-uo
Converts only UDFs (user defined features)
-x
Exports the annotated expressions to a <filename>.exp_txt file
The other thing worth knowing is that for all intents and purposes NX works just as well with a combination of parts in different units. So and assembly can contain all metric parts with a range of imperial fasteners designed in inches quite successfully. Ask yourself first whether you really need to convert the parts.
i have been away from NX for a little over a year as the place i was at went under and now i am a monkey using catia. i miss NX. (if i ever get back to NX i will never complain about the amount of mouse clicks again!!)
Anyway here is a little interface that simplifies the use of ug_convert_part.
