You can change the display of a model in the Schematic Editor in several ways using the Schematic Editor options toolbar and Schematic Editor grid toolbar. The former deals primarily with components drawn in the Schematic Editor, whereas the latter involves display elements. The schematic in the centre of Figure 2 represents one without any options enabled, and the surrounding schematics show the effect when the controls on toolbar buttons are turned on. Figure 13 shows the contextual menu when you right click in the Schematic Editor.

Note: You can select multiple components in one of two ways:
|
Several commands are available when you right-click a component or a selection of components in the Schematic Editor (Figure 1):
- Edit opens the selected component's feature editor where you can edit its configuration
- Rename the selected component
- Activate selected component(s) if it has previously been deactivated
- Deactivate selected component(s), see below for details.
- Multi-activate activates the selected component and either all upstream component or all downstream components (including all components in tributaries), based on your choice from the sub-menu.
- Multi-deactivate deactivates the selected component and either all upstream components or all downstream components (including all components in tributaries), based on your choice from the sub-menu.
- Add opens a sub-menu listing all nodes. Select a node from the list and it will be added at the place you clicked. This option is synonymous to dragging a node from the node palette on to the schematic. It is only visible in the contextual menu if you right click on a blank area in the Schematic Editor, rather than on a component.
- Copy the selected component(s)
- Delete removes the selected component(s) from the scenario
- Paste the selected component(s) you have previously copied
- Apply Params to All Links applies the parameters of the selected link to all links in the scenario
- Routing Type changes the type of the selected link. Choose the link routing type from the resulting sub-menu
- Line Type changes the representation of the selected link to either elbow (orthogonal) lines (Figure 2, left pane) or a straight line (Figure 2, right pane). 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
- 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. See below for more information.
Grid Settings... opens the grid settings dialog (Figure 3). Here you can choose to:Anchor GridSettings GridSettings - 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 (Figure 5).
- Toggle whether nodes will snap to the grid when moved within Schematic Editor using Snap to Grid. Turning this setting on does not affect the alignment of existing nodes. Alignment with the grid is only enforced when you drag a node. Figure 3 compares the appearance of the Schematic Editor with the Snap to Grid control turned off (left) versus on (Grid Size is 50 pixels in centre and 100 pixels on right). The default state is off but the setting is saved with your project. This is synonymous to the Snap to Grid button in the Schematic Editor toolbar (Figure 5).
- Change the frequency of grid lines using Set Grid Size. 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 to entering the grid size in the Schematic Editor toolbar (Figure 5).

- You can work with links and nodes in the Schematic Editor using Allow Link Draggedthe Schematic Editor using Enable connecting link to a different node. This button allows you to disconnect the downstream end of a link from the node to which it is attached, and then reconnect that link to the upstream inlet of another node. You can use this feature to insert new nodes into a schematic without losing the configuration of existing links.
Straight Lines
controlstoggles the representation of links
. Source defaults to drawing links using orthogonal (elbow) lines. Click this button to change the default representationto straight lines
. The left and centre schematics of Figure 15 show the difference between how a model will be represented after you press the bottom. The(eg. Figure 2, centre and left schematics) from the default of orthogonal (elbow) line (Figure 2, right schematic). 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 Typethe Link Type sub-menu.
EachEach 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.
Node Labels controls whether the names of nodes are shown in the Schematic EditorInfo icon false 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. Figure 5. Schematic Editor toolbar
- Note/Error icons toggles the view of any notes and/or errors that are present in theSchematic Editor.
- Node Labels toggles the view of node names the Schematic Editor. Source defaults to displaying node names . The schematic on the centre of Figure 15 shows the behaviour of theSchematic Editor with the Node Labels control turned on(Figure 2, centre schematic).
- Link Labels controls whether toggles the names of links are shown in the Schematic view of link names in the Schematic Editor. Source defaults to displaying link names . The schematic on the right of Figure 15 shows the behaviour of theSchematic Editor with the Link Labels control turned on.Track (Schematic Editor options toolbar) controls whether the Schematic Editor always scrolls to show components as they are selected in the Project Hierarchy. The (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 the Schematic Editor the Schematic Editor window unchanged, regardless of any selections you may make in the Project Hierarchy. If you turn Track on, 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.Overview Panel controls whether the Overview Panel is shown in the Schematic Editor
- Overview Panel toggles the display of the Overview Panel in the Schematic Editor. The default state of this control is off. The schematic on the bottom left of Figure 15 shows the behaviour of theSchematic Editor with the Overview Panel control turned on. You can use this button to the Overview Panel to obtain a thumbnail view of your entire schematic. You You can drag the Overview Panel to the Overview Panel to any point within theSchematic Editor but the Schematic Editor, but you cannot pan the Schematic Editor by the Schematic Editor by dragging within the Overview Panelthe Overview Panel.
- Pan - controls movement of the drawing surface. When this button is when enabled, clicking and holding on any part of the drawing surface in the Schematic Editor moves the Schematic Editor moves the entire drawing surface. This is an alternative to using the scroll bars.
- Set/Delete Background Image allows to add, remove or hide the background image:
- Set Background Image - when selected, display the screen to add a selected image to the model as the background, and default types of the background image are JPEG, PNG and GIF format;

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.

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.
| Info | ||
|---|---|---|
| ||
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.
