There is a number of possible simple-reasons for this error.
Depending on where you work ( small / big company) If you have multiple users you might like to centralize things like templates and settings.
For templates one can set the UGII_TEMPLATE_DIR which will tell NX where to find the pax files for file - new and also Sheet templates. ( I.e when you insert a sheet into an existing drawing file.) In case you work native the template parts should be in the same directory. If one sets this variable and the directory is missing the pax files, - the described message is the result.
Open the NX logfile, Help - NX Logfile, then in that search for UGII_TEMPLATE_DIR
- If it exists, verify that the directory contains a .paxfile named
ugs_sheet_templates.pax
If not, copy the file from your install directory\ugii\templates to the specified directory.
Then test again.
If the variable does not exist, the paxfiles and the parts can exist in the directories specified by UGII_SITE_DIR or UGII_GROUP_DIR or UGII_USER_DIR under the \startup\ directory.
If the paxfiles do not exist under these NX will look in the default directory UGII_BASE_DIR\ugii\templates
Search the logfile for ".pax" and you can see the address of the paxfiles the NX did load.
