There are a number of options for creating a model in the AutoCAD client:

• Create a model from scratch—You can create a model in AutoCAD. Upon opening AutoCAD a Drawing1.dwg file is created and opened. Likewise an untitled new HAMMER CONNECT hydraulic model is also created and opened if HAMMER CONNECT has been loaded. HAMMER CONNECT has been loaded if the HAMMER CONNECT menus and docking windows are visible. HAMMER CONNECT can be loaded in two ways: automatically by using the “ HAMMER CONNECT for AutoCAD” shortcut, or by starting AutoCAD and then using the command: HAMMER CONNECT. Once loaded, you can immediately begin laying out your network and creating your model using the HAMMER CONNECT menus and the HAMMER CONNECT file menu (See Menus). Upon saving and titling your AutoCAD file for the first time, your HAMMER CONNECT hydraulic model files will also acquire the same name and file location.
• Open a previously created HAMMER CONNECT hydraulic model—You can open a previously created HAMMER CONNECT model. If the model was created in the Stand Alone version, you must import your HAMMER CONNECT hydraulic model while a .dwg file is open. From the HAMMER CONNECT menu select Hydraulic Model -> Import -> HAMMER CONNECT Database. Alternatively you can use the command: _wtgImportProject. You will have the choice to import your HAMMER CONNECT database file (.sqlite) or your HAMMER CONNECT hydraulic model file (.wtg).
• Import a model that was created in another modeling application—You can import a model that was created in EPANET. See Importing and Exporting Data for further details.
