How do I open a WaterGEMS model that is already associated with a ArcGIS MXD file?
This wiki assumes that you have already have an existing project which you have previously created in WaterGEMS or SewerGEMS for the ArcMap platform.
Open WaterGEMS for ArcMap.
2. Click the WaterGEMS V8i menu, choose "View" > Add new project. This will open up the Project Manager window. In more recent versions of the software you will go to View > Hydrologic Model
3. In the Project Manager (Hydraulic Model Manager) window highlight the project name by single left clicking it then click the second icon on top that looks like a folder opening to open the WaterGEMS model.
After you do this you will notice the project folder in the Project Manager window will switch from grey to blue and it will have a red check mark on it showing the project is now open. Now you can continue editing or performing calculations on your model as necessary.
