Chamfer

Alias: C H A

Bevels the corner between two lines or polyline segments by replacing it with a straight chamfer line.

---

Description

The Chamfer command trims or extends two lines (or adjacent polyline segments) to meet at a bevelled corner. The chamfer can be defined either by two distances measured along each line from the intersection, or by a distance along the first line and an angle.

When both distances are zero, Chamfer behaves like a sharp trim — both lines are extended or trimmed to their intersection with no chamfer line added.

Workflow

1. Type C H A and press Space or Enter.

2. Optionally set options before selecting objects:

   • Distance — Specify the chamfer distances along the first and second lines.

   • Angle — Specify the chamfer length along the first line and the chamfer angle.

   • Trim — Choose whether the original lines are trimmed after the chamfer is applied (Trim or No trim).

   • Method — Switch between Distance and Angle modes.

3. Select first line: Click the first line or polyline segment.

4. Select second line: Click the second line or adjacent polyline segment.

The chamfer line is drawn between the two chamfer points and, in Trim mode, the original segments are shortened accordingly.

Options

Option	Description
Distance	Set the chamfer distance along the first line (Dist1) and the second line (Dist2).
Angle	Set the chamfer length along the first line and the angle of the chamfer from that line.
Trim	Toggle trim mode. In Trim mode the lines are shortened to the chamfer points. In No trim mode the chamfer line is added without modifying the original lines.
Method	Switch between Distance mode and Angle mode.

Tips

• Setting both distances to 0 trims both lines to their sharp intersection with no chamfer line.

• The first line you select determines which end is chamfered when using Angle mode.

• Chamfer works on adjacent segments of a polyline as well as on two separate lines.
