The child of a 'Block' construct can be assigned in the 'Block Definition Diagram' via drag-and-drop. Both the "to-be" parent and child 'Block' constructs must be added to the diagram first before the parent can be assigned. Below is an outline of the steps for assigning a parent in a 'Block Definition Diagram':

  1. Within a 'Block Definition Diagram', select the child 'Block' of which you would like to assign the parent.

    Select Parent Block

  2. Click the green circle and continue to hold down the left mouse button.

    Click New Composition

  3. Drag the green circle over to the parent 'Block' of your choice.

    Drag New Composition

  4. When the parent 'Block' box highlights green, release the left mouse button over the 'Composition (decomposed by)' section to add a decomposes/decomposed by relationship.

    Drop New Composition

  5. Once added to the diagram, the new relationship should appear as an arrow between the two (2) 'Block' constructs as shown below:

    New Composition Relationship

  6. Click the 'Save' button located on the toolbar to persist your changes to your project's database.
