When changes for library parts are needed, edit the part family table and republish changes from within the Content Center. In addition to general properties such as nominal diameters and materials, you can customize some properties that can only be modified from within the Content Center, such as the library file naming schema, stock number, part number, size designation, and so on.
Library edits may request login to the Autodesk Data Management server and edit permission. If you are working in a single user environment, you automatically have permissions to perform editing tasks within the Autodesk Data Management server on your local drive. If the Content Center is installed on a remote server, you must be assigned with edit permission to perform any of the editing tasks.
In this exercise, you practice the workflow which is based on a predefined library part. From within the Content Center, you customize the part family file naming convention, modify key columns, add new part members, and then republish the revised library part family. Changes do not take effect until the library part is republished.
