To Modify the Start Point or Direction of a Chain
 |
This topic discusses chain modification while working inside of a tool and using the Chain dialog box. If you want to modify a chain while working outside of a tool, you can use the SHIFT key to clear the selection of individual items from the ends of a chain or use the CTRL key to remove an entire chain from the selection set. Refer to About Selection under See Also for more information about clearing a selection.

1. Construct the chain and open the tool in which to work with the chain, or select a feature that contains an existing chain that you want to modify and click Edit Definition.
2. Locate the Detail collector that contains the chain that you want to modify. Detail collectors are located on the panel. Note that you cannot use the Summary collector (located on the dialog bar) to modify a chain.
3. Click Details. Creo Parametric pauses the tool, opens the Chain dialog box, and displays the attributes for the chain.
4. If the panel Detail collector contains more than one chain, select the chain to modify from the chain list in the Chain dialog box. The chain attributes are displayed.
5. Click the Options tab.
6. To change the start point and direction of an open-ended chain (One-by-One, Tangent, and Partial Loop), click Flip. Creo Parametric reverses the chain start point and direction. Skip to step 9.
7. To change the chain start point location of a closed-loop chain (One-by-One or Complete Loop), click the Start Point collector. After the collector is activated, select any vertex from the chain on your model as the new start point location. Notice that you can also use the Start Point shortcut menu command from inside the graphics window to activate this collector.
8. To change the chain direction of a closed-loop chain, click Flip. Creo Parametric reverses the chain direction.
9. Click OK. Creo Parametric saves the changes, closes the Chain dialog box, and resumes the tool.

• Notice that as you modify a chain in the Chain dialog box, Creo Parametric dynamically displays the changes in the graphics window.
• To clear references in the active collector, click Remove or Remove All on the shortcut menu that appears when you right-click in the collector. Alternatively, click Clear on the shortcut menu that appears when you right-click in the graphics window.
• To easily locate references in the Chain dialog box, place your pointer over the reference in a collector. Creo Parametric dynamically highlights the reference on the model.
• To remove the Start point handle, right-click the handle and click Remove on the shortcut menu. The End point handle appears. Similarly, to remove the End point handle, right-click the handle and click Remove on the shortcut menu. The Start point handle appears.
