NX File Name Method
To define drawings using the file name method, the server-side preference Define Drawing must be set to the value "file name."
When the Define Drawing preference is set to “file name,” then you must also set the server-side preference Drawing File Name. If the option is not set, then no NX CAD parts are created as drawings (no matches).
When the preference Drawing File Name is set to a naming pattern, then files with names that match the specified naming pattern are created as CAD documents of type Drawing at their first upload to Windchill.
You may use the characters described in the following table to set the value for Drawing File Name:
Character
Description
\
The character that follows the backslash is part of a special sequence. For example, \t is the TAB character. Can be used to escape the other pattern matching characters: ( ? * [ ] ^ ). To match the backslash character, use "\\".
?
Wildcard that matches a single character. For example, the string "abcde" is matched by the expression "ab?de"
*
Wildcard that matches zero or more characters.
[ ]
Defines a set of characters, from which any can match. For example, the string "abcde" is matched with the regular expression "ab[cxx]de"
^
Indicates a negation. For example, the expression [^ab] matches anything but the 'a' or 'b' characters.
* 
NX file names are not case-specific, so the pattern matching is always performed ignoring case.
