- Click OK.
Saving a project
To save an open project, choose . This saves a project file with the extension *.mxproj. If it is the first time you are saving your project, the Save As dialog opens and gives you the opportunity to choose the location and name of your project file. By default, the name of the file is the name of your project. If you wish to save a different version of your file, choose
Closing an open project
To close an open project, choose . This closes the current project and prompts to save your work as shown in below Figure. Click the appropriate button.
Opening an existing project
To open an existing project, either:
- Choose File » Open Projector
- Click Open Project on the File toolbar.
This opens the standard Windows™ open dialog as shown in Figure below. Note that opening a new project prompts you to save any open project.
Copying projects
You can duplicate existing projects by copying them. In your local machine's File Explorer, select the desired project, right-click and choose Copy. In the target location, right-click and choose Paste.
Components of the main screen
Project Explorer
The Project Explorer (Figure below) allows you to manage model components using a combination of the menu bar, the Project Hierarchy, the Model Parameters area, and pop-up menus. For an active scenario, clicking an item in the Editor highlights it in the Project Hierarchy.
Model parameters
The Model Parameters area (as shown in above Figure) shows which parameters will be recorded for the scenario element (node, link etc) that is currently highlighted in the Project Hierarchy. The indicators have the following meanings:
Every parameter at this level and below will be recorded; 
No parameters at this level and below will be recorded;
Some (but not all) parameters at this level and below will be recorded.
To change which parameters are recorded, first select an element in either the Project Hierarchy or Model Parameters area, then use either the Recording Options pop-up menu on the Project Explorer toolbar, or the contextual menu to change the setting. Note that these commands are hierarchical in nature and affect both the selected element and its logical children as displayed in the visual hierarchy.
Data Sources
The Data Sources tab allows you to view and manage time series at one location in Source. When time series are added using the Data Sources Explorer, they are available for use throughout Source. For more details on using this, refer to Specifying data inputs.
Function Manager
The Function manager panel allows you to create, manage and maintain all functions defined in Source. Just as all data in the Data Sources Explorer is available throughout Source, all functions added in the Function manager can be used in the same way.
Node Palette
The Node Palette contains a list of icons representing the nodes that are supported by Source. To create a node-link network, drag icons from this palette onto the Schematic Editor’s drawing surface.
Layer Manager
The Layer Manager (Figure 4) is mainly associated with the Geographic Editor. It is visible by default when you create a new catchments scenario. Choose if the Layer Manager is not visible. You can add new layers, and move layers up and down in order of visibility. The checkbox next to a layer’s name indicates that the layer is visible in the Geographic Editor. Note that any layers that are added or removed are not persisted in the scenario.

Recording Manager
The Recording Manager displays a list of all the recorded results from the model run or runs. Each model run has its own tab. You can sort the results by clicking the column headings. The associated with this window gives quick access to common functions.
Log Reporter
The Log Reporter displays any errors, warnings or information messages resulting from user actions, or events that have occurred when running a scenario. You can choose to display or hide different types of events by clicking the Errors, Warnings, or Info tabs at the bottom of the Log Reporter.
Chart Recording
Chart Recording allows you to compare the results of different scenario runs. You can change certain parameters in a scenario to see how the output is affected. Refer to Chart Recording Manager for more information on this.
Working with the Source window
Just as with standard Microsoft applications, you can adjust panels within the Source window. This provides great flexibility when working with very large models.
