To add a part class to the Catalog hierarchy, you must edit the Excel workbook for your task.
Before you modify a workbook, save a backup copy. That way, you can always bulk load the previous data.
When you add a part class to an existing classification folder, you just need to edit the R-ClassNodeDescribes sheet. When you add a part class to a new classification folder, you must edit the ClassNodeType, R-Hierarchy, and R- ClassNodeDescribes sheets.
You must also add a specific part class sheet to the workbook. You can copy an existing part class sheet and modify it as necessary. You must create the symbol definition for the new part using Visual Basic, Solid Edge, or 2D Symbols.
If you add new part classes after creating the Reports databases, you must re-create the Reports databases in order to report on the new part classes.
