In this lesson you will learn how to build, change and configure diagrams. (Starting with the diagram you have created in the previous lesson)
Popup-menu's are frequently used in this lesson. Almost every object in a diagram has it's own popup-menu. You can activate this popup-menu by positioning the mouse cursor on the object and pressing the right mouse button. The popup-menu of the diagram itself can be activated by positioning the mouse on an emtpy area of the diagram and pressing the right mouse button.

Once you have arranged everything, you should end up with a diagram similar to this one:

It is possible to select and drag corner points, they even have a popup-menu. In the popup-menu you can select options like hiding the corner point. It is possible to create multiple corner points in each line. If multiple points are selected (by dragging a selection over them), multiple points can be dragged.
2. Open the popup-menu from a corner point and select Lock. The corner point is now locked and cannot be moved. 3. Unlock the corner point again. 4. Using the popup-menu hide a single point. 5. Using the popup-menu select the item to make the entire line straight to remove all corner points.
Zooming diagrams in and out
1. Open the Diagram menu and select Zoom, 125%. The diagram will be enlarged. 2. Open the Diagram menu and select Zoom, Zoom Out. 3. Ctrl-Minus and Ctrl-Plus may be used to zoom. 4. Panning and zooming can also be performed using the Ctrl, Shift and Mouse wheel.

2. Type a name for the diagram style:
3. Click OK. The new style can be found in the configure diagram menu and can be used for future projects as well:

2. Unselect the Display expressions and Display tupels, select Fact name position left and click Ok. Look at the result in your diagram. 3. Re-open the properties window, select both expression-optins again and align the fact name position back to middle. Click Ok. You can change the properties of multiple objects at the same time by selecting the objects and choosing the Properties option from one of their popup-menu's. Drag a selection over the items or hold the shift-key to select multiple items.
Using the alignment functions
1. Keep the shift-key pressed and select Student, Apprenticeship Assignment and Apprenticeship Preference. 2. Select Align from the Diagram menu:
3. Select Horizontal Left and click Ok. Note: The left sides of the fact types have been placed exactly on the same line. 4. Drag the fact type Assigned Apprenticeship to it's original position.
Printing a diagram
1. Select the diagram tab. 2. Open the File menu and select Print Diagram: 3. Select Page Fit. 4. Click Print to print the diagram. If no printers have been installed the preview area will be empty. 5. Save the project by selecting Save Project from the File menu. Some printers will not print the entire diagram as shown by the preview window. (Random pieces of the diagram will be missing). This is mostly in case the diagram is to complex to fit into the printer's memory. You can prevent this problem by selecting a raster-printing option in the printer driver (instead of vector-printing). Some fonts will be displayed too large in the print preview window. In that case the font cannot be sized smaller then displayed. This has no effect on the printed result!
