To Create a D x D Chamfer

In the graphics window, select the references from which to create the chamfer. Notice that the chamfer propagates across tangent neighbors until it encounters a break in tangency. However, if you use a One-by-One chain, the chamfer does not propagate across tangent neighbors.
Note: Press CTRL+click to select additional references for the active chamfer set or to remove a reference.
Click on the Feature toolbar or Insert > Chamfer > Edge Chamfer. The Chamfer tool opens and Pro/ENGINEER displays preview geometry. Notice that the selected references are in the References collector on the Sets slide-up panel.
Click Sets. On the Sets slide-up panel, select the chamfer creation method that you want to use. The default chamfer creation method is Offset Surfaces.
Select the D x D dimension scheme from the Dimension Scheme box on the dialog bar. The default chamfer dimension scheme is D x D. You can also select this scheme from the shortcut menu.
To define the distance, drag the distance handle to the preferred distance or snap it to a reference. Pro/ENGINEER displays the distance value in the graphics window and dynamically updates the preview geometry.
Note: You can also type a new value or select a most recently used value from the D box on the Dialog Bar. The same method applies to the distance box in the Distance table (D column) located on the Sets slide-up panel.
At this point the chamfer is complete. If you need to define the chamfer further, refer to the topics under See Also for more information.
Click to save your changes. Pro/ENGINEER creates the chamfer and closes the Chamfer tool.

Tip:

If you are using a chain as a reference and you want to modify it, click Details on the Sets slide-up panel and use the Chain dialog box.
To quickly define a distance, simply double-click the distance value in the graphics window. After the box opens, type a new value and press ENTER, or select a most recently used value from the list.
You can always select Default in a most recently used list to enable Pro/ENGINEER to determine the value.
As you work in the graphics window, you can use Clear from the shortcut menu to clear all references from the active collector.
To remove a reference from within a collector, select the reference that you want to remove, and with your cursor still in the collector right-click and select Remove from the shortcut menu.
