Is it possible to reverse pipe orientation in bulk/batch?
As of version 10.00.00.XX, the fastest way to reverse pipes in bulk is to use ModelBuilder:1. Create a new FlexTable, and make the Table Type 'Pipe' or 'Conduit'.2. Add the "Label", "Start Node", "Stop Node" and "Flow" fields (if needed)3. Filter the pipes if required so that the FlexTable only contains pipes with negative flows (i.e. the pipes you want to reverse). Or, filter by other criteria as needed.4. Click "Export to File" and save in CSV format.
5. Open the CSV file in Excel (you will probably need to run through the Text Import Wizard).6. Swap the "Start Node" and "Stop Node" column labels, then Save as an .XLS file7. Use ModelBuilder to update the pipes in your model with the reversed Start and Stop nodes. These fields are found at the top of the step, just under the Key Field:
Note that for WaterCAD and WaterGEMS, the flow direction can change during an extended period simulation, so you may not want to reverse all pipes. Also note that there is a result field called "Flow (absolute)" that just returns the magnitude of the flow (without any negative signs), which you may be able to use instead of running though this process.
