Working with 2D Objects
Add Visual Objects
There are two ways to add the visual objects in a GeoSWMM 2D project:
- Using 2D Tools
- Using ArcGIS Pro map Edit section
The drag-and-drop system is available for only GeoSWMM 1D model. Although it is relatively smarter and more efficient in adding object data into a GeoSWMM project, the users need to use 2D modeling tools to add 2D visual objects. In addition to that conventional GIS editing approach is also accessible in adding the objects.
Add Boundary Layer Feature
To add Boundary layer using 2D tool:
Click on Define Boundary Layer tool
Select the “Start” option to draw features and “Import” option to import layers into the boundary layer.
Assign the attribute fields properly, and
Click “OK” to save the features in to the boundary layer. Boundary layer will be saved in the project GDB.
To add boundary layer features using the conventional ArcGIS Pro edit section:
Select the Boundary Layer in the SWMM geodatabase in the ArcGIS Pro map.
Go to Edit to start drawing a new feature. Arc GIS Pro edit option will become active.
Assign the required attributes for the created or edited features.
After feature editing is complete, save and stop editing the layer.
Add Nodes 2D Layer
To add 2D Nodes layer using 2D tool:
Click on Create 2D Nodes tool.
Boundary layer is directly assigned from project geodatabase.
Provide Obstruction layer from ArcGIS Pro map TOC or browse.
Provide DEM layer from ArcGIS Pro map TOC or browse.
Click “Create” to generate 2D nodes feature in the Nodes 2D layer.
To add 2D nodes features using the conventional ArcGIS Pro edit section:
Select the Nodes 2D Layer in the SWMM geodatabase in the ArcGIS Pro map
Left Click and go to Edit Section and “Start” Editing Now Create or edit the features in the selected layer using the options provided in the ArcGIS Pro Edit Section.
Assign the required attributes for the created or edited features.
After feature editing is complete, save and stop editing the layer.
Add 2D Layers
To add 2D layers using 2D tool:
Click on Create 2D Layers tool
Boundary layer and Nodes 2D layer are directly assigned from project geodatabase
Obstruction layer and DEM layer is directly assigned from Create 2D Nodes tool
Select any option available in “Extract elevation data from”
Click “Create” to generate 2D layer features i.e. Junction 2D, Conduit 2D and Cell 2D
To add 2D layer features using the conventional ArcGIS Pro edit section:
Select the 2D Layers, i.e., Junction 2D, Conduit 2D or Cell 2D in the SWMM geodatabase in the ArcGIS Pro map
Left Click and go to Edit Section and “Start” Editing
Now Create or edit the features in the selected layer using the options provided in the ArcGIS Pro Edit section
Assign the required attributes for the created or edited features
After feature editing is complete, save and stop editing the layer
Add 2D Orifice
To add 2D orifice using 2D tool:
Click on Connect 1D-2D tool
Select “Connect 1D to 2D with Orifice”
Click “Connect” to develop 1D-2D connections using 2D orifice.
To add 2D orifice using the conventional ArcGIS Pro edit section:
Select the Orifice 2D Layer in the SWMM geodatabase in the ArcGIS Pro map
Right Click and choose “Start” Editing
Now Create or edit the features in the selected layer using the options provided in the ArcGIS Pro Edit section
Create the 2D orifice from 1D junction to 2D junction
Assign the required attributes for the created or edited features
After feature editing is complete, save and stop editing the layer
Add 2D Weir
To add 2D weir using 2D tool:
Click on Connect 1D-2D tool
Select “Connect 1D to 2D with Weir”
Click “Connect” to develop 1D-2D connection using 2D weir.
To add 2D weir using the conventional ArcGIS Pro editi section:
Select the Weir 2D Layer in the SWMM geodatabase in the ArcGIS Pro
Left Click and go to Edit Section and “Start” Editing Now Create or edit the features in the selected layer using the options provided in the ArcGIS Pro Edit Section
Create the 2D weir from 1D junction to 2D junction
Assign the required attributes for the created or edited features
After feature editing is complete, save and stop editing the layer.
Edit Object Properties
GeoSWMM enables the user to edit the 2D model object properties in a number of ways. The property editor can be opened in one of the following ways:
Clicking on the (
) button for a selected 2D object in the SWMM data browser
Double-clicking on a single object name in the SWMM data browser
Clicking on the (
) button in the SWMM data browser (to open the grid editor)
Double-clicking on the 2D object category (e.g. Junction_2D) in the GeoSWMM Object Panel (to open the grid editor)
Delete Objects
To delete a single object from the GeoSWMM 2D project:
Select the 2D object category in the GeoSWMM Object Panel.
Then select the 2D object name in the SWMM data browser and click on the (
) button.
Click Ok to confirm delete.
To delete multiple 2D objects together from the GeoSWMM project:
Select the object category in the GeoSWMM Object Panel.
Then select the 2D objects using Ctrl-key or by dragging the names together in the SWMM data browser, and click on the (
) button.
Click Ok to confirm delete.
