- Rotate rotates the orientation of the selected node(s) to the orientation chosen from the sub-menu. The default direction is 0 degrees, which corresponds to North to South.
- Grid Settings... opens the grid settings dialog (Figure below). Here you can choose to:
- Toggle display of the grid using Display Grid. The default state is off but the setting is saved with your project. This is synonymous to the Display Grid button in the Schematic Editor toolbar.
- Change the frequency of grid lines using Set Grid Size. The default is 10 pixels but the setting is saved with your project.

Straight Lines toggles the representation of links to straight lines from the default of orthogonal (elbow) line. The representation of any link can be controlled independently using the contextual menu in the Schematic Editor. Right-click the link and choose one of the options in the Link Type sub-menu. Each line has one control point which you can adjust to route the line around obstacles. The control point for an orthogonal line can only be moved in the vertical dimension whereas the control point for a straight line has no restrictions on its movement. The representation of any link can be controlled independently using the contextual menu in the Schematic Editor. Right-click the link and choose one of the options in the Link Type sub-menu.
Note: At present, only the setting of the Straight Lines button is saved with your project. Any changes you make to individual links or control points are lost when you close your project.- Note/Error icons toggles the view of any notes and/or errors that are present in the Schematic Editor.
- Node Labels toggles the view of node names the Schematic Editor. Source defaults MUSIC X defaults to displaying node names (Figure 2, centre schematic).
- Link Labels toggles the view of link names in the Schematic Editor. Source defaults MUSIC X defaults to displaying link names (Figure 2, left schematic).
- Track when enabled, the Schematic Editor window will scroll to bring into view any node or link that you select in the Project Hierarchy. You can use this feature to locate components in large models. The default state of this button is off. In this mode, Source leaves MUSIC X leaves the Schematic Editor window unchanged, regardless of any selections you may make in the Project Hierarchy.
- Overview Panel toggles the display of the Overview Panel in the Schematic Editor. The default state of this control is off. You can use the Overview Panel to obtain a thumbnail view of your entire schematic. You can drag the Overview Panel to any point within the Schematic Editor, but you cannot pan the Schematic Editor by dragging within the Overview Panel.
- Pan when enabled, clicking and holding on any part of the drawing surface in the Schematic Editor moves the entire drawing surface. This is an alternative to using the scroll bars.
- Tool tips controls the view of tool tips containing information about a component's name, elevation and type. A storage node contains additional information including its capacity, height and surface area:
Tool tips on – when selected, clicking on any node in the Schematic Editor causes a small floating window to appear that contains additional information about that component;
Tool tips off – when selected, the floating windows do not appear; and
Tool tips locked – when selected, clicking any component in the Schematic Editor causes a small floating window to appear next to every component.
.
- None – when selected, no node is highlighted
- Ordering –when selected, nodes with ordering processed are highlighted
- Constraints – when selected, nodes with constraints processed are highlighted
- Off Allocation – when selected, nodes with off allocation processed are highlighted
- All – when selected, all nodes are highlighted Reset – reset highlighting
- Show/Hide Node/Link Display - controls the view of nodes and links:
- Show link labels - when selected, show link labels
- Show node labels - when selected, show node labels
- Custom display - when selected, show customized display of nodes and link labels
- Configure custom display - by clicking this, a custom display configuration window will pop out,as shown in Figure 6below. Ticking the little box to allow show Icon or show label for nodes and links

- Display Grid toggles display of the grid. This is synonymous with the with the Grid Setting dialog optiondialog option.
- Snap to Grid toggles whether nodes will snap to the grid when moved within Schematic Editor. This is synonymous with the Grid Setting dialog optionGrid Settings... option.
- Set Grid Size changes the frequency of grid lines. The default is 10 pixels but the setting is saved with your project. Figure 4 shows the appearance of the Schematic Editor with a grid size setting of 10 pixels (left), 50 pixels (centre) and 100 pixels (right). This is synonymous with the Grid Setting dialog optionGrid Settings... option.
- Print opens the Print preview dialog allowing you to save the schematic in the Schematic Editor as a pdf. The entire schematic is scaled to fit within a single A4 page in portrait mode. An example is shown in Figure 7;below:
- Save as Image saves the entire schematic in the Schematic Editor as a *.jpg. The entire schematic is scaled to fit within a single A4 page in portrait mode.
- You can view the zoom and undertake various zoom actions using the zoom icons on the right side of the toolbar:
- Current zoom displays the value of the zoom that is currently used in the Schematic Editor. This value has a range of of 10 – 200%;
- Zoom in allows you to zoom into a particular part of the mode (or Ctrl and + on your keyboard's number pad or Ctrl and scroll up with your mouse scroll wheel). Similarly, Zoom out allows you to zoom out (or Ctrl and - on your keyboard's number pad or Ctrl and scroll down with your mouse scroll wheel). Both actions are performed in increments of approximately 10%; and
- The last two icons Fit to width and Fit to window icons ensure that the entire model fits into the Schematic Editor screen. As its name suggests, Fit to width ensures that entire model is visible horizontally in the window. Clicking Fit to window will display the entire model in the window.

Node Rotation
By default, Source nodes have a north to south orientation. If your schematic represents a model that has a different orientation, you can choose to rotate some or all of your nodes to represent this.
You can rotate a node two ways:
- Click on a node to select it. A green circle handle will appear, you can drag the handle to rotate the node (Figure 8, left node).
- Right click a node or a selection of nodes and choose Rotate from the contextual menu (Figure 1). Then choose either the default direction or one of the four compass directions from the sub-menu (Figure 8, right nodes). You can set the default rotation in Edit » Scenario Options, then select Default Node Rotation from the side tree. Nodes added from the node palette will have the default rotation.

Deactivating Nodes and Links
Deactivated components allow water to pass through that component as if it was not there. That is, a deactivated component's downstream flow is always the same as its upstream flow. Similarly constituents and orders are not effected by the deactivated component. This allows you to test the effect of component(s) on the simulation. For example, the effectiveness of a proposed storage can be modelled by running the scenario twice; once with the storage node activated and once with it deactivated.
Performance Improvement
Deactivating large sections of a model (eg. a network branch) will improve performance by decreasing model run-time. This can be useful when you are working with part of a model only, eg. during calibration.
Nodes and links can be deactivated two ways, either:
- select the component(s), right-click to open the contextual menu, select Deactivate; or
- Right-click on a single component, choose Multi-deactivate to deactivate the selected component and either all upstream or all downstream components, based on your choice from the sub-menu.
Deactivated nodes are indicated by a grey circle backlash symbol on top of the node icon. Deactivated links become a solid grey line. Figure 9 shows what happens when the storage alone was deactivated using Deactivate (left pane), or the storage and all upstream components were deactivated using Multi-deactivate » This and all upstream, or the storage and all downstream components were deactivated using Multi-deactivate » This and all downstream including tributaries (right pane).
Figure 9. Deactivation of nodes and links comparison
Note the following about deactivation:
- Multi-deactivate and multi-activate does not work if traversing the network leads back to the starting component, such as an anabranch. Source will notify you if this occurs. For example, it is not possible to use multi-deactivate (either upstream or downstream) on either the environmental demand node or the water user node in Figure 8.
- Two Warning notifications are generated by Source when running a model with deactivated components:
- One indicates how many components were deactivated
- The other indicates how many components were excluded from the run order. Excluding components from the run order will reduce run time.
- Deactivation has not been implemented for a wetland cluster. If a component of a wetland cluster is deactivated, there will be a run time error.
- If a splitter is deactivated, all the flow, constituent and orders are passed down the non-effluent link.
- If a supply point is deactivated, the connected water user will not receive water
