Every pipe in a model does not need to have connectivity defined for PlantWise to route the lines that do have connectivity. However, lines that are either directly or indirectly connected to a pipe without full connectivity cannot be routed. The AutoRouter will generate exceptions for lines that do not have any connectivity information, or if the connectivity definition is incomplete. The "Checking Connectivity" section, next explains how you can identify connectivity problems before the routing process.
