How can I change the direction of flow arrows in Topology view?
You do not need to re-digitize your drawing! The flow direction arrows are displayed based on the drawing and data on how your pipes, diversion, etc are related. Your topology-related data must be complete and correct. Please carefully read the section in the Users Manual “Understanding Topology Data”. Correct any “breaks” in the conveyance system using the Snap Nodes to Pick command in the Topology menu. Check your data on entity types (SY_TYPE) and overflows (SY_IDOVER field). Then, select Verify System Continuity from the Topology menu to refresh the direction of flow displayed. If you have further problems with topology, please call technical support for further troubleshooting.
