About Creating a UDF Library
Before you create a UDF, you may want to create a UDF library directory. By default, the UDF is created in the current directory.
If you create a UDF library directory, make sure all users have Read access permission. When you create a UDF library, copy the UDF files, name.gph and name_gp.prt (for standalone udfs), to this UDF library directory.
To access the UDF library directory in Creo, specify the directory name with the configuration file option pro_group_dir.
You can set up the directory tree to support the UDF library hierarchy. You can easily walk through this directory tree to search for a specific UDF to place on a part as a group. However, when you retrieve a part with a dependent group, the group file must be located in the directory set by the pro_group_dir option.
