In this example, if you select a cell in the Screw Hole table to add a parameter, the entire set of parameters MH_NAME, EFF_DEP, BH_DIA, and BH_DEP are automatically created. Similarly, if you select a cell in the Knock Hole table , the parameters KH_NAME, DIA, EFF_DEP, BH_DIA, and BH_DEP are automatically created.

You can create two-hole features and add parameters defined in the Screw Hole table to this feature. To the other feature, you can add parameters defined in the Knock Hole table. However, if you add parameters at the part level after adding parameters defined in the Screw Hole table, you cannot add parameters from the Knock Hole table. As the parameters EFF_DEP, BH_DIA, and BH_DEP are common to both the tables and are already associated with the Screw Hole table, you cannot add the DIA parameter as a restricted parameter that is driven by the Knock Hole table.

For example, if a part contains both screw holes and knock holes, and you want to add parameters at the part level, as the EFF_DEP, BH_DIA, and BH_DEP parameters exist in both the tables, you must define a table that combines both type of holes as shown in the table below.
