The Schematic Editor allows you to create and manage an operations or schematic scenario.

...

• 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 or all downstream components, based on your choice from the sub-menu.
• Multi-deactivate deactivates the selected component and either all upstream or all downstream components, based on your choice from the sub-menu.
• 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:
  • 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 display toolbar (Figure 6). 
  • 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 display toolbar (Figure 6). 
  • 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 display toolbar (Figure 6).

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.
