When you specify a scope for the row or a column, you can choose from one of the following options:

  • Containment
  • Structure
  • Custom

The simple way to define the row/column scope is to drag the needed package or element onto the scope field or choose them from the Element Selection dialog. In this case, the Containment option is selected.

For more advanced cases you can choose the Structure or Custom options.

You can build a custom tree-like view for the rows and columns of the matrix. Currently it is possible to build a tree hierarchy by specifying your own criteria. You can select the predefined Structure criteria which builds the same hierarchy as in the Structure Tree in Model Browser.

If you need to collect elements that are not necessarily owned by the same package, you can specify the query in the Row/Column Query dialog, and see the results added to it immediately.

An example of the Row Query dialog

To specify the row/column scope query


  1. Click the Specify Row/Column Query icon in the Row/Column Scope field.
  2. In the Row/Column Query dialog, select one of the following:
    • Containment. Select if you want that the row/column elements would be displayed as in the Containment tree. Owned elements will be collected recursively starting from the elements specified as scope values.
    • Structure. Select if you want that the row/column elements would be displayed as in the Structure tree. This option is available only when the SysML Plugin is installed.
    • Custom. Select if you want to make your own adjustments. Select the Build Hierarchy check box to recursively execute the specified expression for building multilevel hierarchy starting from the scope as the root.

      If you have selected Customspecify the expression.

  3. Click OK.
