To edit an existing chamfer in AutoCAD, the most direct and efficient method is to interact with the chamfered edge directly within your drawing.
Editing Existing Chamfers Using the Chamfer Editor Dialog
The primary way to modify an existing chamfer is by using the dedicated editor that appears upon direct interaction:
- Double-click the chamfered edge on your drawing.
- Upon double-clicking, the Chamfer Editor dialog will automatically appear. This dialog box provides a user-friendly interface to modify the chamfer's properties.
- Within this dialog, you can adjust various parameters, such as the chamfer distances for both adjacent edges, or the chamfer length and angle, depending on how the chamfer was originally created and the options available.
- After specifying your desired changes in the dialog, confirm them to instantly update the chamfer on your object.
This method allows for precise control over the chamfer's dimensions without needing to recreate it.
Understanding Chamfer Parameters
A chamfer is a beveled edge that connects two surfaces, often used to eliminate sharp corners. When editing, you'll typically adjust parameters that define its size and angle relative to the original intersecting edges.
Here are the common parameters you might encounter in the Chamfer Editor dialog or Properties Palette:
| Parameter | Description |
|---|---|
| Distance 1 | This value specifies the distance from the original corner along the first selected line or edge to where the chamfer begins. |
| Distance 2 | Similarly, this value defines the distance from the original corner along the second selected line or edge to where the chamfer begins. If Distance 1 and Distance 2 are equal, the chamfer is symmetrical. |
| Length | The total length of the chamfered segment itself, measured along the new beveled edge. This is often an output of the distances/angle. |
| Angle | The angle of the chamfer relative to one of the original lines or edges. This is used in conjunction with one distance to define the chamfer. |
Alternative Editing Approaches
While double-clicking provides direct access to the Chamfer Editor, other AutoCAD tools can also be utilized for modifying chamfered objects, especially when the chamfer is part of a larger 2D polyline or 3D solid:
- Properties Palette (CTRL+1): When you select an object containing a chamfer (e.g., a 2D polyline), the Properties palette will display its characteristics. For polyline segments that have been chamfered, you might be able to modify the associated chamfer distances or other geometric properties directly from this palette.
- Grips Editing: For chamfers that are integral to 2D polyline segments, you can sometimes use grips to dynamically reshape the polyline. Moving a vertex adjacent to a chamfer will cause the chamfer to adjust accordingly, maintaining its relative position to the new geometry.
- Re-applying the CHAMFER Command (for new parameters): While not "editing" in the sense of modifying an existing feature directly, you can delete an existing chamfer or the lines forming it and then re-apply the
CHAMFERcommand with entirely new distance or angle settings to create a new chamfer. However, the double-click method is superior for direct modification.

Utilizing the Chamfer Editor dialog via double-clicking is the most straightforward and recommended approach for precise adjustments to an already existing chamfer in AutoCAD, ensuring accuracy and efficiency in your drafting workflow.
