Proximity Trace View

The Proximity Trace View is used as part of the Proximity Trace procedure. The proximity trace searches for nodes that lie within a specified distance of a pipe to which the node is not connected. This may indicate connectivity problems and identify locations where nodes should be connected into adjacent pipes.

The view is displayed by choosing Tracing tools | Proximity trace from the GeoPlan menu while a network is open.

Select/Deselect all Click this button to check/uncheck all boxes in the Results list.
Show log

Check this option to display a log of changes made to the network after connectivity has been corrected.
Snapping options

Select the snapping option to be used when the Correct connectivity button is clicked:

  • Snap link to node - attempt to snap the adjacent pipes to each of the selected nodes
  • Snap node to link - attempt to snap each of the selected nodes to the adjacent pipe
Flag Select a flag to be applied to recalculated link fields (e.g. length, US node ID, DS node ID).
Correct connectivity button

Click this button to correct the connectivity of the objects selected in the Results list.

The Move Node dialog will be displayed. Use the options on this dialog to correct connectivity by snapping the nodes and links together according to the selected snapping option.
