Change a chamfer
1. Click Modeling and then, in the Engineering group, click the arrow next to Chamfer.
2. Click Modify. The Modify Chamfer dialog box opens.
3. Select a Type: Distance, Dist/Dist, or Dist/Angle.
4. Click Chain Selection if you want to select all tangentially connected faces with a single click. The sequence of faces stops when two faces are not tangentially connected, that is, when a face intersects a corner, for example.
5. Click Chamfers and select a chamfer in the viewport. Press Shift to select multiple chamfers.
Select a chamfer in the viewport and click on the Command Mini Toolbar (CMT) to modify that chamfer.
While modifying a chamfer, drag the CoPilot arrows, press the SPACEBAR, and select Distance on the Option Mini Toolbar (OMT). The options available on the OMT depend on the selected element.
6. Set the chamfer values:
Type value(s) for Distance.
Type a value for Angle, if required.
Drag the guide arrows in the viewport.
Click Propagate to propagate the change in a chamfer distance to subsequently-selected chamfer if possible. For example, if you change the distance of a chamfer from 8 to 12 and then select other chamfers, the distances of other selected chamfers also change to 12.
Click Restore to restore the distance of the chamfer to the value before the currently-active selection. Old Chamfer Definition shows the value of the distance of the chamfer before the active selection.
Click Clear active selection to deselect the selected chamfers.
7. Other options:
Feedback: Shows a wire frame preview of the chamfer.
Labels: Add distance labels to each chamfer to show where the entered values are applied. The Labels option in the Create Chamfer dialog box adds labels to each chamfer with distance. To change the default setting for labels, see Change Modeling settings.
Dragging: Displays the CoPilot handles. Drag the handles to change the distance of the chamfer.
Chk & Fix: Check and attempt to fix self-intersections, knife edges, and void shells. If a part fails the check and fix, it is not modified and remains in its original state.
Click Preview to preview the model with chamfers.
You can click either Realistic or Quick to see either realistic feedback or quick feedback when you chamfer an edge in the viewport. See Realistic feedback.
8. Click to complete the operation.
The chamfer value cannot be zero or less than zero.
