To Delete Transitions and Make a Transition
1. Select the references for the round and click Model > Round. The Round tab opens.
2. Click to switch to Transition mode. Preview geometry of all transitions is shown for the entire round feature.
 
* You can also use Show transitions from the shortcut menu to change to Transition mode.
3. In the graphics window, select a transition to delete, right-click and select Delete transition from the shortcut menu. The system deletes the transition and frees the references. If needed, repeat this step to delete another transition.
 
* The deleted transitions must share the same geometrical location in order to make a new transition.
4. Hold down the CTRL key and select all of the round piece ends that are freed by the deleted transitions. The selected round piece ends are highlighted.
5. Right-click and choose Make transition from the shortcut menu. The system configures the new transition according to the geometrical context and displays it in the graphics window. Notice that the transition type for the new transition is displayed in the Transition Type box on the Round tab, and on the shortcut menu.
 
* If you do not select Make transition, the system restores the default transitions for the freed references because the geometrical input did not change and the transitions with the best fit for the geometry was again selected.
6. If you want to change the transition type for the new transition, select the new type from the Transition Type box on the Round tab, or from the shortcut menu.
7. At this point, the new transition is complete. Do one of the following:
◦ Make another new transition.
◦ Click to return to Set mode and continue working with round sets.
◦ Click to save your changes, create the round, and close the Round tool.
 
• To return to the default transition after making a new transition, delete the new transition and click . The system switches to Set mode and restores the default transitions. Proceed to step 2.
• You can also delete a transition from the Transitions list on the Transitions tab by using Delete transition on the shortcut menu.
• If you delete the wrong transition, right-click and select Back to sets. The system switches to Set mode and recreates the default transition. Proceed to step 2.
• If you made an error selecting a round piece end, right-click and choose Clear from the shortcut menu. Then, select the preferred ends. Remember to use the CTRL key as you select multiple round piece ends.
