- Toggle display of the grid using Snap to Grid. The default state is off but the setting is saved with your project. Figure 5 compares the appearance of the Schematic Editor with the Snap to Grid control turned off (left) versus on (50px centre and 100px right). Turning this setting on does not affect the alignment of existing nodes. Alignment with the grid is only enforced when you drag a node. The default state is off but the setting is saved with your project. The grid does not need to be visible for alignment to occur.;
- Change the frequency of grid lines using Set Grid Size. The default is 10 pixels but the setting is saved with your project. Figure 5 shows the appearance of the Schematic Editor with a grid setting of 10 pixels (centre) and 50 pixels (right). This is synonymous to right clicking on the Schematic Editor and choosing Grid Settings...;
- You can view a sample printed copy of the model displayed in the Schematic Editor using Print (Schematic Editor grid toolbar). At present, the entire schematic is scaled to fit within a single A4 page in portrait mode. An example is shown in Figure 6.;
- You can save a Source model in .JPEG format using Save as Image (in the Schematic Editor grid toolbar).This command opens a standard file dialog box so that you can choose where to save the image. At present, 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 (or Ctrl + on your keyboard) allows you to zoom into a particular part of the model. Similarly, Zoom out (or Ctrl - on your keyboard) allows you to zoom out. Both actions are performed in increments of approximately 10%; and
- The last two 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.
