Adding existing excludes dependencies to a diagram
You can add existing Excludes Dependencies to a diagram in the following ways:
Through the Populate > Constraint Dependencies command from a Variation Point or Variant.
Through the Populate > Variability Dependencies command from the diagram background.
Through the Excludes Dependency toolbar button.
To populate a variation point's or variant's excludes dependencies:
Right-click the Variation Point or Variant, point to Populate, and then click Constraint Dependencies.
Modeler populates missing Excludes and Requires Dependencies for the Variation Point or Variant you right clicked, adding to the diagram any Variation Points or Variants that are required to show those missing Excludes Dependencies.
To populate excludes dependencies that link items shown on the diagram:
Right-click the background of the diagram, point to Populate, and then click Variability, Artifact, Constraint Dependencies.
Modeler populates Excludes Dependencies (and Artifacts, Requires and Variability Dependencies as well) that are missing between items shown on the diagram.
To add an existing excludes dependency to a diagram through the excludes dependency toolbar button:
1. Ensure that the two items that are linked by the Excludes Dependency are shown on the diagram.
2. On the Variant Diagram or Variability toolbar, click the Excludes Dependency button.
3. Click the first Variation Point or Variant.
4. Click the linked Variation Point or Variant.
Modeler adds the Excludes Dependency that is missing between the two items on the diagram. If no Excludes Dependency exists between the two items, Modeler creates an Excludes Dependency.
