Connector Properties

A connector can have a wide range of properties, with some connector types having fewer, simpler properties and others having more and more-complex properties. You edit these properties on either the:

  • '<connector type> Properties' dialog or the
  • Properties window for the connector

Some properties are visible on a diagram as text labels on or around the connector, and you can change these labels using the 'Label' context menu.

The connector properties are presented on these tabs:

  • General
  • Advanced properties - on the 'Properties' dialog
  • Tags (Tagged Values) - on the 'Properties' dialog
  • Source and Target Roles
  • Constraints
  • Template Bindings



Start > Explore > Properties > Properties > click on connector in a diagram > Connector   (Properties window)

Design > Element > Properties > Properties > click on connector in a diagram > Connector   (Properties window)

Context Menu

Right-click on Connector | Properties   ('Properties' dialog)


Alt+1 > Connector   (Properties window)


Double-click on Connector     ('Properties' dialog)

General Options

These options are available on the 'Connector > General Settings' panel of the Properties window, or the 'General > Main' tab of the 'Properties' dialog.

(Optional) Type a representative name for the connector; this name displays on the diagram.


('Properties' dialog, Optional) Type any comments you want to record on the connector. You can format the text using the Notes toolbar at the top of the field.

These notes can be included in searches, reports and documentation, if required.

Notes Window Notes Toolbar


(Properties window) Displays the connector type selected when creating the connector.


(Optional) Type the name of a stereotype for the connector, or click on the Browse. button and select the stereotype from the 'Stereotype Selector' dialog.

If specified, the stereotype is displayed on the diagram and it over-rides the connector type in the report documentation.

Stereotype Selector


Displays the name of the source element for the connector.


Displays the name of the target element for the connector.


(Optional) Type an alternative name or alias for the connector.


Displays the direction of the connector. For some connectors (such as an Association), you can change the direction: click on the drop-down arrow and select the appropriate direction details - from source to destination, destination to source, bi-directional, or unspecified.

Some connectors have arrow heads that depend on this setting, and some connectors are logically dependent on it (such as Inheritance).


Click on the drop-down arrow and select the appropriate connection style; choose from:

  • Direct
  • Auto-Routing
  • Custom
  • Tree (Vertical, Horizontal, Lateral Vertical or Lateral Horizontal), or
  • Orthogonal (Square Corners or Rounded Corners)

Some connectors can also have the Bezier style, under which the connector follows a smooth curve.

Virtual Inheritance

(For Generalization connectors) Click on the drop-down arrow and select True or False to indicate if inheritance is virtual or not.


(For Generalization connectors where the child Class is C++.) Click on the drop-down arrow and select the appropriate value for the scope (used for inheritance).


  • Instead of displaying properties on tabs in the 'Properties' dialog, you can display the properties on screen pages selected through a hierarchical list; select the 'Property Sheets use Tree style' checkbox using the 'Start > View > Visual Style' ribbon option
  • The 'Binding' tab is displayed for Generalize, Realize, Associate and Template Binding connectors; use this tab to define binding expressions and parameter substitutions for the connector
