About Extending Chamfer Geometry
You can extend chamfer geometry (pieces) to achieve the preferred chamfers for your model. As you create a chamfer, the chamfer geometry automatically propagates across tangent points and then stops at a non-tangent point. If you need to continue the chamfer geometry, you can extend the chamfer piece up to a patch that you select. The following table illustrates the extend process.
You can only extend open chamfer sets. If you want to work with a closed-loop chamfer set, you must first use open the chamfer geometry.
You cannot extend separate (overlapping) chamfer pieces. To remove one of these pieces, hold down the CTRL key and select the piece, or clear it from its respective collector.
If you need to extend chamfer geometry at a different point other than a patch, you must define a Stop at Reference transition.
The system uses an automatic blend to fill the gap around a corner. This blend cannot be modified or deleted. If a blend cannot be added, extend cannot be performed.
Extending Chamfer Geometry
The chamfer placement edge reference is selected and the chamfer geometry stops at non-tangent points (a).
The chamfer piece is selected from the Pieces tab and the trim/extend handles appear (b). As the right handle is dragged to extend the chamfer piece, potential extension geometry appears. Notice that blend transitions are automatically added where a gap exists between tangent points. Also notice that the cursor and handle change during extending.
Using the potential extension geometry as a guide, the handle is dragged to extend the chamfer piece up to the third patch (c). Notice that the potential extension geometry outline changes color indicating the extent of the extension.
Release the mouse button, and the chamfer piece is extended up to the patch (d).
