Connectivity Trace
Connectivity tracing scans the model and finds all the physically separate sub-networks within it. This is a useful check to see if the model is fully connected.
The connectivity of the network will also be tested when the network is validated. At this stage, validation will fail if any node is found that is not connected to an outfall node in the network.
To carry out a connectivity trace, open a network and then choose Tracing tools | Connectivity from the GeoPlan menu. This displays the Connectivity Trace View, containing a list of the separate sub-networks found, with node and link counts for each.
Finding sub-networks
Use the Find Selected SubNetworks button to select and zoom in on the sub-networks currently selected on the Connectivity Trace View.
- Any existing network object selections are cleared
- All the objects in the network(s) are selected on the GeoPlan Window
- The view is zoomed in to the maximum extent possible while still displaying all the selected objects
Deleting sub-networks
Click Delete Selected SubNetworks to delete the sub-networks currently selected on the Connectivity Trace View.
This operation will delete all the objects in all the sub-networks selected on the Connectivity Trace View, even if the selection on the GeoPlan Window or Network Object Grid Windows has changed.
Unconnected links
Click Select Unconnected Links to select all links that have missing nodes at both ends of the link.
Click Delete Unconnected Links to delete all links that have missing nodes at both ends of the link.
