Uncheck the box next to to remove that unnecessary value from the Table of Contents dialog.
After doing this, and two new symbols should appear (0-Inactive, and 1-Active). In the Value Field dropdown menu select Is_Active and then click Add All Values.In the Layer Properties dialog select the Symbology tab, click on Categories in the left pane and select Unique values.on the pop up dialog box and click on the Symbology tab of the layer properties dialog. In the ArcMap table of contents right click on a layer, and select Properties.This will not be re-applied to the network view when re-opening the project, until the project is re-loaded from the Hydraulic Model Manager.Using WaterGEMS as an example, this would be going to the Bentley WaterGEMS menu in the Toolbar, then View > Apply WaterGEMS Renderer). The symbology defined using this method will not be applied when "Apply Renderer" is enabled.The steps below will need to be completed for each Layer (i.e., OpenFlows element type).Note that our development team will investigate the possibility of improving the product to prevent the Renderer from having to be re-applied each time, for a future version. At a later point if you apply other color coding to elements (for example to color by pipe diameter) you will need to re-apply the Renderer (step 1).Unchecking the box next to Display Inactive Topology will remove inactive elements from the drawing (they will disappear) and the box to the right controls the color inactive elements will display with. In the Options dialog, select the Global tab. To control how inactive elements display in the drawing view, open the Bentley menu, select Tools, and click Options.A checkmark next to the setting indicates it's enabled. To enable these settings, open the "Bentley " menu, select View and select each setting. Enable "Apply Renderer" and "Auto Refresh".This is the intended approach and tends to be the most straightforward. There are two ways to view and edit the display of active topology for elements in the ArcGIS/ArcMap platform. WaterGEMS, SewerGEMS, and HAMMER for ArcMap
Once this is completed, you can display active topology in the model by going to the WaterGEMS-View tab and select Apply Active Topology > Apply Active Topology. This step is also used to apply color coding and flow arrows. If you have not already done so, go apply the Join GeoTables function by going to the WaterGEMS tab, then choosing Join GeoTables > Add Joins. The steps below use WaterGEMS as an example. Note: In order to integrate with ArcGIS Pro, you will need WaterGEMS version 10.03.02.75 and SewerGEMS version 10.03.03.44. The workflow between ArcGIS Pro and ArcMap is a little different. When using these products in ArcMap, with the default configuration, setting elements to be inactive will only toggle the "Is Active" attribute in the GeoTable and will not automatically control the actual visibility in the network view. In standalone, when an element is set to be inactive ("Is Active?" = False), it will display as configured in the Options menu (Tools > Options > Global tab), which is typically either a gray color, or non-visible. The display inactive topology setting for Bentley products (WaterGEMS, SewerGEMS, HAMMER) in ArcMap or ArcGIS Pro works differently than it does in the standalone products.
How can I control the display of Active Topology for elements on the ArcGIS Pro and ArcMap Platform? Background
