Navigate to the '''TUFLOW_SWMM_Module_01\Tutorial_Data''' folder in Windows Explorer. Drag and drop '''SWMM_Culverts.gpkg''' into QGIS to open the file. SWMM_Culverts.gpkg includes three Layers, Links-Conduits, Nodes-Junctions and Nodes-Outfall. Links-Conduits defines the culvert location, type and geometry. Nodes-Junction define the upstream culverts inverts. Nodes-Outfall define the downstream culvert inverts.
Complete the following steps
# Copy the objects from '''Links-Conduits SWMM_Culverts.gpkg''' into '''Links-Conduits TS01_001.gpkg.''' Steps to Copy/Paste are as follows:
#* Left click '''Links-Conduits SWMM_Culverts.gpkg''' in the QGIS Layers Panel.
#* Use the select the Feature by Area tool. to select all items included in '''Links-Conduits SWMM_Culverts.gpkg'''
#* Select Edit >> Copy Features
#* Left click '''Links-Conduits TS01_001.gpkg''' in the QGIS Layers Panel.
#* Select Toggle Editting to enable changes to be made to the Layer.
#* Select Edit >> Paste Features
'''<< Add video for Copy Paste>'''
# Copy the objects from '''Nodes-Junction SWMM_Culverts.gpkg''' into '''Nodes-Junction TS01_001.gpkg'''
# Copy the objects from '''Nodes-Outfall SWMM_Culverts.gpkg''' into '''Nodes-Outfall TS01_001.gpkg'''
# Close '''SWMM_Culverts.gpkg'''
# Inspect the attribute information within the respective layers to familarise yourself with the data.
'''<< Add video for viewing attribute data>>'''
We will update the ''From Node'' and ''To Node'' attribute information in '''Links-Conduits TS01_001.gpkg'''. The information is extracted from '''Nodes-Junction''' and '''Nodes-Outfall''' automatically using the ''Conduits - Assign Node Fields'' tool from the Processing Toolbox.
# Select (Left mouse click) '''Links-Conduits TS01_001.gpkg''' in the QGIS Layers panel and Toggle Editing on.
# From the Processing Toolbox, select "''Editing in place"''. This allows the editing of an existing Layer, instead of the creatin of a new Layer
# Select the ''Conduits - Assign Node Fields'' tool.
# Select '''Nodes-Junction''' and '''Nodes-Outfall''' in the SWMM Node Layers field.
# Select Modify All Features.
# Close the ''Conduits - Assign Node Fields'' tool.
View the attributes associated with Links-Conduits TS01_001.gpkg. The ''From Node'' and ''To Node'' attribute information is now configured correctly.
