====Node Details====
The 'From Node' and 'To Node' attribute information in '''Links---Conduits''' is necessary to build the 1D SWMM network. It defines the link/node connections. The information we will be adding to '''Links--Conduits''' is extracted from '''Nodes--Junctions''' and '''Nodes--Outfalls''' automatically using the '<u>[[QGIS_SWMM_Conduits_Assign_Node_Fields |Conduits - Assign node fields]]</u>' tool from the Processing Toolbox.

<li>In the QGIS Layers panel, select (left click) '''Links--Conduits''' and toggle on editing.
<li>In the Processing Toolbox, select the 'Edit Features In-Place' tool [[File:edit_features_in_place_icon.png]]. This allows the editing of an existing layer, instead of the creation of a new layer.
<li>Go to TUFLOW > SWMM in the processing tool list and select '<u>[[QGIS_SWMM_Conduits_Assign_Node_Fields |Conduits - Assign
<li>Tick on the SWMM Node Layers: '''Nodes--Junctions''' and '''Nodes--Outfalls'''.
<li>Select 'Modify All Features'.
<li>Once the tool has finished, click 'Close'.
<li>Turn off editing to save the edits.
<li>View the attributes associated within '''Links--Conduits''' to verify the data processing has been completed correctly. The 'From Node' and 'To Node' attribute information is now configured correctly. For a broader understanding of the other attributes associated with the '''Links
'''Tip:''' If you wish to only update selected objects during a future modeling project, instead of the entire '''Link--Conduits''' dataset, select the target objects first using the Feature by Area tool. The '<u>[[QGIS_SWMM_Conduits_Assign_Node_Fields |Conduits - Assign node fields]]</u>' tool will provide an option to 'Modify Selected Features', instead of 'Modify All Features.'
