In order to facilitate the drawing of pleasing diagrams, various alignment tools are provided. These are available from the main "View->Position" menu item, from the main toolbar or by right-clicking on the diagram's canvas area to select the "Position" menu items. These are as follows:
Zoom in / Zoom out: | Zoom in and out of the diagram. This is also available on the toolbar as a combo box. You can also Zoom in and out by holding the Ctrl key and scrolling the mouse wheel. |
Snap to Grid: | Snaps elements to the Grid whether it is visible or not. (Grid spacing can be set in Preferences.) |
Grid Visible: | Toggles the visibility of the Grid. (Grid spacing can be set in Preferences.) |
Snap to Alignment Guides: | These are blue alignment guides (lines) that appear when elements are dragged in a diagram. They assist in lining the edges and centres of elements. |
