1. Change the drawing selection filter to Feature.

2. Select the feature to re-dimension.

3. Right-click and click Redefine Feature from the shortcut menu. The feature opens in a new window. If you selected the base feature, only the section of the base feature and dimension values appear in the separate window. If you selected a later feature on the model, the system rolls back the model and displays it in default orientation in a separate window. The section and dimensions of the feature (if applicable) appear on the model.

4. Add and delete dimensions, or change placement constraints, as necessary. You cannot modify existing dimension values or add or delete features.

5. Save and close the re-dimensioned feature. The model regenerates to reflect the changes.
