After you add a model with a design table, and specify the external parameters, you can select the rules that govern the model. Rules include: Basic Rules, Design Table Rules, and Hierarchical Rules.
If you select to use Hierarchical Rules to govern the model's behavior, you can select to use the data in your design table as the basis for the hierarchical rules that exist between parameters.
You can assign relationships to some of the
parameters, save the changes, and return later to assign relationships
to the remaining parameters. Or you can edit existing relationships. Before
you run the Design Table Data Migration,
set the rule mode to Hierarchical Rules.
If you decided to enter your data rather than migrate existing design table data, use the Hierarchical Rules Wizard.
If you are migrating existing design table data, follow the procedure listed next.
To run the Design Table Data Migration:
By definition, the first parameter cannot
have a relationship since it has no antecedent. However, position is relative
if you selected to rearrange the parameter order. When you start the Hierarchical Rules wizard, the existing
dimensions for the first parameter are listed.
Under the Relationship column for the second parameter, select from the list to determine what type of relationship you want to establish between this parameter and the preceding parameter.
No relationship exists between the two parameters. For example, any one parameter can be associated to any other parameter, regardless of its position in the design table.
The two parameters are associated to each other, but not to any other parameters in the model. For example, when associating length(1) to width(1), a one-to-one relationship indicates the following: For each value of length(1) on this model, there is only a single value for width(1) that is valid. In a design table, these values appear along the same row in the design table. If you selected to enter new data, you can only associate a single length(1) for every width(1).
The two parameters are associated to each other, but not to other parameters in the model. For example, when associating length(1) to width(1), a one-to-many relationship indicates the following: The length(1) on this model can use any of the values for width(1) that are included in the design table. Or it can include relationships to any length (1) and width(1) parameters that you add.
Once you select a relationship, the existing parameters are listed next to the preceding parameter for your reference. The contents of the list depend on the type of relationship you selected.
Design tables with one-to-one and one-to-many relationships.
Under the Dependent Parameter column, click from the list to select the parameter you want to associate with its antecedent.
If this is the second parameter, you
can only associate it with the first parameter.
For any subsequent parameters, the list displays all prior parameters. However, not all relationships are valid. If you select a relationship which the model cannot support, an error message appears, prompting you to try a different dependent parameter or a different relationship.
Click Finish.
Returns to the Parameters dialog box.
To view and edit parameter information, click Edit next to any parameter.
