The Diagram Behavior page of the Options dialog enables you to define how a diagram responds to actions taken on it.



Use to

Auto Instance

Automatically create object instances when dragging certain element types - such as Class and Component - from the Project Browser, with the dragged element as the classifier.

Instance has Classifier style

Automatically apply the classifier style of the element an instance is instantiated from when the instance is created.

Show Life Lines

Show life lines for Sequence elements in non-Sequence diagrams.

Layout uses all relations

Show all relationships in a diagram layout; deselect the checkbox to show only Generalizations and Associations.

Auto Save Changes

Automatically save your changes as you work, without having to confirm prompts to do so.

Show 'Hidden' Parents

Display any parents of elements in the diagram that are not part of the diagram.

Auto Group Elements

Also move visually composed elements when moving diagram nodes. A node is considered composed if it is contained by the moved element and has a higher z-order. Press and hold [Alt] whilst moving an element to toggle this option.

Show Package Item Scope

Display the + and - indicators representing the scope of the items.

Snap all elements to the grid lines.

Show Grid

Display the grid.

Grid Size

Specify the grid size, if you have selected Objects Snap to Grid.

Auto Tidy

Automatically tidy line angles for custom connectors. This 'nudges' the custom line into horizontal and vertical increments.

Tidy line gap

Specify the amount Enterprise Architect should enable you to move a line away from horizontal and vertical when you are tidying lines for custom connectors. (See Auto Tidy above).

Alias only

Display the alias instead of the element name on elements with aliases.

Alias and Name

Display both the element name and the Alias in the format (Alias) name.

Use alias field for role

Replace the Alias property of instances with a Role property.
