To Define Dimension Boundaries in an Inheritance Feature
1. Retrieve an assembly, select a part in it, right-click, and choose Activate.
2. Select a second part in the assembly as the reference model from which geometry will be copied and click Get Data > Merge/Inheritance. The Merge/Inheritance tab opens with the reference model selected by default. You can select a different part as the reference model from the Model Tree or in the graphics window.
3. Click
to toggle between Merge mode (default) and Inheritance mode.
5. Select a dimension from the Varied Items list, then select one of the following value limits from the New Dim Bound list:
◦ Upper—Sets the dimension value to its maximum (generates geometry based on a nominal dimension value plus the tolerance).
◦ Middle—Sets the dimension value to the nominal value plus the mean of the upper and lower tolerance values.
◦ Lower—Sets the dimension value to its minimum (generates geometry based on a nominal dimension value minus the tolerance).
◦ Nominal—Sets the dimension value to nominal (generates geometry based on exact ideal dimensions).
| If the New Dim Bound column does not appear in the Varied Items dialog box click, and add it. |
6. Click OK.
| To redefine the varied dimension boundary, right-click the Inheritance feature in the Model Tree, and choose from the shortcut menu. |
