The R-ClassNodesDescribes sheet maps the classification folder names to the part classes. For example, the delivered Cabling.xls workbook lists a classification folder called CablesNode. A classification folder can have one or more part classes. The CablesNode classification folder is associated with the Power Cables, Communication Cables, Radio Frequency Cables, Fiber Optic Cables, and Hybrid Cables part classes on the R-ClassNodeDescribes sheet.
All children of a classification folder must be part classes. You cannot mix part classes with folders beneath a classification folder.
