Unfortunately, the snapping tolerance set by XPSWMM for its Node GIS Data Export function is larger than the underlying model information it is associated with. This can cause a slight offset in the data. To rectify this issue, we will use a processing tool designed to assist in this task.
<ol>
<li> In the QGIS Layers panel, select (left click) the inlet usage layer (i.e. '''swmm_iu_XP_001'''
<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 'Vector geometry' in the processing tool list and select 'Snap geometries to layer'. This opens the dialog shown below.
:* Reference Layer: '''Nodes--Junctions'''. This is the layer we want the
:* Tolerance: '0.1 meters'
:* Behavior: 'Prefer aligning nodes, insert extra vertices where required'
<li> Click 'Modify All Features'. Once the tool is finished, click 'Close'.
<li> Toggle off the editing for the inlet usage layer (i.e.'''swmm_iu_XP_001''') to save the edits.<br>
