For proper P&ID correlation when you use the software in an integrated environment, Smart P&ID and Smart 3D must use the same naming convention for piping components and equipment.
One example is piping reducers. You can open the Excel workbook for piping components in Smart 3D, and change the name "Concentric Size Change" to "Concentric Reducer". Alternatively, you can copy the existing rows and add new entries, as shown below. Save the workbook, and bulk load it into the Catalog.
