SewerGEMS For ArcGIS [FAQ]

Product(s): SewerGEMS
Version(s): 08.11.XX.XX, 10.XX.XX.XX
Area: Modeling

How do I open an existing SewerGEMS model inside ArcMap?

First, open ArcMap. Then, click the SewerGEMS V8i menu, choose "Project" > Add Existing Project. Select your SewerGEMS model and then click the blue folder icon in the next window, to attach a geodatabase. A separate geodatabase is necessary for ArcMap to interact with the SewerGEMS model. It is recommended that you save a new geodatabase. For example, name it MyModelgdb.mdb and save it in the same folder as your SewerGEMS model. Ensure that you assign the correct coordinate system/spatial reference, before clicking OK in the window that shows the blue folder icon. When you click OK, the Table of Contents will be populated with the SewerGEMS element types and your model should appear. You may need to use the zoom extents button or zoom to an element using the search button at the top of the SewerGEMS properties window.

First, open ArcMap. Then, click the SewerGEMS V8i menu, choose "Project" > Add new project. Choose a location to save the SewerGEMS model and then click the blue folder icon in the next window, to attach a geodatabase. A separate geodatabase is necessary for ArcMap to interact with the SewerGEMS model. It is recommended that you save a new geodatabase. For example, name it MyModelgdb.mdb and save it in the same folder as your SewerGEMS model. Ensure that you assign the correct coordinate system/spatial reference, before clicking OK in the window that shows the blue folder icon. When you click OK, the Table of Contents will be populated with the SewerGEMS element types and you can now lay out or import your SewerGEMS model. 

How can I convert my GIS to a SewerGEMS model inside ArcMap?

First, follow the steps above for creating a new SewerGEMS model. Then, use Modelbuilder to import the GIS. Modelbuilder is located under the "Tools" menu inside the SewerGEMS V8i menu. Select ArcGIS geometric network or ArcGIS Geodatabase features as the data source type, select your geodatabase features to import and follow the subsequent steps.

Basically it determines the fields available in ArcMap's attribute tables. 

Which versions of SewerGEMS support which versions of ArcGIS?

See below article:

Compatibility Chart

Note that versions of ArcMap earlier than the ones listed in this article are also supported. The chart shows the latest available versions that were fully certified.

Since the SewerGEMS menus always show up in Arcmap, am I always using a SewerGEMS license? What if I want to use ArcMap without SewerGEMS?

As of version 08.11.01.21, SewerGEMS license utilization only occurs when you open a SewerGEMS project (Via SewerGEMS > View > Project manager). For previous versions (08.11.00.08 and below), license utilization will always occur. For information on un-integrating older versions of SewerGEMS with ArcMap, see problem number 35731 in the Knowledgebase.

After working on a project in ArcGIS mode and saving a .mxd, why does the SewerGEMS model not appear when reopening the .mxd? 

After reopening the map, you must first load the SewerGEMS project, under SewerGEMS > View > Project Manager.  

When working in ArcGIS mode, why are the tools in the SewerGEMS layout toolbar grayed out? 

First, you must open or create a SewerGEMS model in your current map, using the Bentley SewerGEMS > Project menu. (see further above) Also, you must be in editing mode to use the tools. Go to Editor > Start Editing.   

How can I enable the flow arrows and active topology colors when working in ArcGIS mode? 

Go to Bentley SewerGEMS > View > Apply SewerGEMS renderer.  

What is the easiest way to color code SewerGEMS elements inside the ArcMap platform?

Click the element type layer from the table of contents, then click the Bentley SewerGEMS V8 menu, choose Tools > Layer Symbology. This tool will allow you to use the familiar SewerGEMS color coding interface to automatically create ArcMap symbology entries. 

When annotating or color coding in the ArcMap platform, why aren't all the SewerGEMS attributes available?

The attributes available to color code/annotate on are dictated by the attributes included in the geotables. So, click the Bentley SewerGEMS V8 menu > View > Flextables. In the Flextables manager, open the "Geotable" corresponding to the element type in question. Use the yellow 'edit' button to choose the attributes thatwill be available to color code/annotate on.
