Most diagram tools are self-explanatory, and are just shown in the images. This section provides details for a few that require some explanation.
Select (Pointer) tool. Pan tool. Magnify Select Magnify and hover over the diagram to display a magnified section of the diagram. Zoom Drag the cursor diagonally to define the area to which you want to zoom. Interactive Zoom Drag the cursor up to zoom out. Drag the cursor down to zoom in. Link Navigator Shows the path of a link using a simple animation. Default Layout Returns the diagram to the default layout. To display the layout list, click the arrow next to the button and select a new layout from the list of options. Circular Layout It is available in the layout list. See Circular Layout. Orthogonal Layout It is available in the layout list. See Orthogonal Layout Symmetric Layout It is available in the layout list. See Symmetric Layout. Hierarchical Layout (Oblique) It is available in the layout list. See Hierarchical Layout. Print Setup. Sets options for printing the diagram or elements of the diagram. See Printing a Diagram. Print Preview. Lets you see how the printed diagram would look. Print. Prints the diagram. Export to Image. Exports the diagram to one of the five available image file formats, and lets you save the image file locally for future reference. See Exporting a Diagram to an Image. Labeling Prevents labels from overlapping with other elements and labels in the diagram. Link Routing Redraws the diagram, attempting to redraw only the links, leaving resource nodes in the same size and position where possible.The behavior of link routing is affected by the preference options Fix Node Size and Fix Node Position. See Reference to Diagram Preferences for details. Fit In Window Zooms the diagram to fit the size of the current diagram editor view. Refresh Diagram. If you make changes in the project, clicking Refresh Diagram updates the diagram with the changes. Zoom Percentage Zooms the diagram to the specified percentage. Search Entities. Allows you to search for BusinessEvents entities in the diagram.Layout options refer to the style of the diagram that is rendered in the diagram editor, Rule Debugger, and Dependency panel.
Various options affect the appearance of a diagram, no matter what layout is chosen. (The hierarchical layout offers additional options.) See Reference to Diagram Preferences for more details.This layout is useful for ontologies where nodes tend to have a clustered (ring or star) structure (where each main node has a starburst of related nodes).The algorithm places highly connected nodes closer together, resulting in a more compact diagram. Even when lines overlap, the algorithm ensures that they are still easy to follow. Because this style has no hierarchical or other visual constraints, the resulting diagrams are often very clear.The symmetric layout style looks for and emphasizes the symmetries in a project topology. It can produce a pleasing visual result, if there are no reasons to arrange the nodes. For example, there is no hierarchy or ring-clustering inherent in the structure of the nodes.The hierarchical layout style indicates dependencies by positioning the nodes at different levels. The hierarchical layout style is useful when you need to show precedence relationships in the ontology. You can use Layout Preferences to determine in the direction of the hierarchy. Preferences and options specific to the hierarchical layout are:
• Orientation Options (Edit > Preferences)—Left to Right, Top to Bottom, Right to Left, Bottom to TopSee Reference to Diagram Preferences for more details.Choose Incremental Layout if you want the main arrangement of the diagram to remain stable when you make changes to your project and only re-route the entities and links that have changed since the last rendering.Keeping most things in the same place makes it easier to see how changes you have made in the project affect the diagram.If you want to refresh the entire diagram, click the desired layout option. The program has greater freedom to optimize the layout. The result is likely to be a more pleasing arrangement.
