View source for QGIS SWMM Conduits Assign Node Fields

== Introduction ==
This tool provides users with the ability to reliably and efficiently assign the 'To Node' and 'From Node' fields of a conduits layer. It identifies the nodes snapped to the endpoints of conduits and assigns the 'To Node' and 'From Node' appropriately.
<br>
This tool supports in-place editing if selected in the QGIS processing window.

== Usage ==
This tool, '''Conduits - Assign node fields''', can be found in the QGIS processing toolbox panel under TUFLOW >> SWMM. To open the Processing Toolbox panel, navigate to 'Processing' in the menubar and select 'Toolbox'.<br>

=== Parameters ===
<ol>
<li>'''Input layer:''' The existing conduits layer to which the 'To Node' and 'From Node' fields will be assigned. 
<li>'''Selected features only:'''  If channel(s) in the conduits layer have been selected using the 'Select Features' tool, this option will become available. If checked on, the tool will only assign the 'To Node' and 'From Node' fields to the selected channel(s).
<li>'''SWMM Node Layers:''' The existing node layers that are snapped to the endpoints of the channel(s) in the conduits layer.
<li>'''Conduits:''' Determines the location and filename of the output conduits layer. 
</ol>
'''Note:''' If 'Edit Feature In-Place' is selected, the tool only requires the 'SWMM Node Layers' parameter. That is, the tool will override the existing conduits file with the updated 'To Node' and 'From Node' fields.
