To Define a Chamfer Transition

Note: This topic is a Master Procedure in that some transitions require that you follow an additional topic to complete the procedure. If you select one of these transitions, simply follow the instructions.

Select the references for the chamfer and click . The Chamfer tool opens.
Click on the Dialog Bar to switch to Transition mode. Pro/ENGINEER displays preview geometry of all transitions for the entire chamfer feature.
Note: You can also use Show Transitions from the shortcut menu to activate Transition mode.
In the graphics window, select the transition that you want to define. Pro/ENGINEER makes the transition active.
Select one of the following transition types from the Transition Type box on the Dialog Bar, or from the shortcut menu and follow the procedure for that transition type.
Note: Pro/ENGINEER determines the valid transition types according to the geometrical context of the selected transition. This means that not every transition type listed below will be available to you for a particular transition.
Default—Pro/ENGINEER determines the transition type that is the best fit for the geometrical context. The transition type appears in parenthesis. Proceed to step 6.
Blend—Create a fillet surface between the chamfer pieces using an edge reference. Proceed to step 5.
Continue—Extend chamfer geometry into two chamfer pieces. Proceed to step 5.
Intersect—Extend two or more overlapping chamfer pieces toward each other until they merge forming a sharp boundary. Proceed to step 5.
Corner Plane—Chamfer the corner transition formed by three overlapping chamfer pieces with a plane. Proceed to step 5.
Patch—Create a patched surface at the location where three or four chamfer pieces overlap. Click To Define a Patch Transition under See Also to define this transition.
Stop Case 1—Terminate the chamfer using geometry configured by Pro/ENGINEER. Click To Define a Stop Case Transition under See Also to define this transition.
Stop Case 2—Terminate chamfer using geometry configured by Pro/ENGINEER. Click To Define a Stop Case Transition under See Also to define this transition.
Stop Case 3—Terminate chamfer using geometry configured by Pro/ENGINEER. Click To Define a Stop Case Transition under See Also to define this transition.
Stop at Reference—Terminate chamfer geometry at the selected datum point or datum plane that you specify. Click To Define a Stop at Reference Transition under See Also to define this transition.

Pro/ENGINEER displays preview geometry of the transition and adds the selected transition to the Transitions list located on the Transitions slide-up panel. Notice that Pro/ENGINEER displays only user-defined transitions on this list. If you want to remove a transition from the Transitions list, see the note at the end of this topic.

If you want to cap the gaps between the active transition and part geometry by creating end surfaces, click the Capped check box located on the Dialog Bar. Notice that this check box is available only if you select a transition type (other than Default) and use the Surface or New quilt attachment type (see About Chamfer Attachment Types). Pro/ENGINEER clears this check box by default.
Note:
Side surfaces must exist in order to extend and use them as capping surfaces. If not, the chamfer piece cannot be capped.
This check box caps only the gaps between the active transition and part geometry while the Create end surfaces check box located on the Options slide-up panel caps all chamfer piece ends for the entire chamfer feature. Remember, the Dialog Bar check box overrides the slide-up panel check box. This enables you to cap the gaps of the active transition even if you decide not to cap all of the chamfer piece ends for the chamfer feature.
You cannot cap chamfers between a solid surface and a quilt surface.

At this point, the transition is defined. Do one of the following:

Define another transition.
Click to return to Set mode and continue working with chamfer sets.
Note: You can also use Back to Sets from the shortcut menu.
Click enabling Pro/ENGINEER to save your changes, create the chamfer, and close the Chamfer tool.

Note: If you want to restore the default transition, select Default from the Transition Type box on the Dialog bar, or from the shortcut menu. Pro/ENGINEER does not display default transition types on the Transitions list.

Do not use Delete Transition from the shortcut menu to remove a transition type from the Transitions list. If you do use it, you can do one of the following to restore the default transition type: Press CTRL+Z to undo the selection (or Edit > Undo setting), switch to Set mode, or close the Chamfer tool.

Tip:

You can also use Capped from the shortcut menu to cap the gaps of the active transition.
To preview various transitions before selecting one, simply place your cursor over each transition type in the Transition Type box. Pro/ENGINEER highlights the corresponding transition geometry in the graphics window.
