The steps below will show how to create a new project in WaterGEMS. The same steps can be applied to SewerGEMS or HAMMER.
1) Open WaterGEMS for ArcMap.
2) Click the WaterGEMS menu, choose "Project" > Add new project (or "hydraulic model").
3) Choose a name for the project and location to save the WaterGEMS model. Click the "Save" button to proceed to the next step.
4) Click the blue folder icon in the 'Attach Geodatabase' window to create a new geodatabase
This is necessary because WaterGEMS interacts with ArcMap through this separate personal geodatabase (.mdb file). Note: If you get a message that says "WaterGEMs project cannot be a geodatabase" this means that the name you tried to give your geodatabase has the .wtg extension in it. Simply remove the extension and your new geodatabase will be created.
Ensure that you assign the correct coordinate system/spatial reference, before clicking OK in the 'Attach Geodatabase' window.
When you click the "Ok" button, the Table of Contents will be populated with the layers for WaterGEMS element types and you can now lay out or import your WaterGEMS model.
