Where can i find udf files (location in NX installation folder) that i have made.
Menu > Tools > User Defined Feature > Configure Library > Reload
The default location for these files is C:\Program Files\Siemens\NX 11.0\UGII\udf
how can I delete a UDF, is there any option in wizard, insert or replace options.
To replace you could try "Menu > Tools > User Defined Feature > Replace...".
To delete, you'll have to locate your udf_database.txt file (per Configure Library) and then remove the line referencing your UDF. You can then delete the corresponding UDF part and image file (typically the path defined in the Default File Directory per Configure Library, if it's not saved in the udf_database.txt file). You can also replace a UDF using the same manual edit procedure of the udf_database.txt file.
Yes you can edit the UDF definition.
To do this locate the UDF part file as described earlier and open that part in NX. You can now add/modify/delete features etc. as required. Then if you double click the UDF feature (last one in the tree) the wizard dialog will open up where you can change the features included and define new parameters, references etc.
NOTE: If you want to delete any features it is important that first you edit the UDF definition and remove them from the list of included features. If you don't do this, deleting the feature will also delete the UDF definition!
