First line

It specifies the first of two edges required to define a chamfer.

Select the second line.

If lines or polylines are selected, their lengths adjust to accommodate the chamfer line.

If the selected objects are segments of a polyline, they must be adjacent

Undo

It reverses the previous action in the command.

Polyline

It chamfers a full polyline.

Select the polyline:

The segments of the intersecting polyline are chamfered at each vertex of the polyline. Chamfers become new segments of the polyline.

If the polyline includes segments that are too short to accommodate the chamfer distance, those segments will not be not chamfered.

Distance

It sets the distance of the chamfer from the ending point of the selected edge.

Specify first chamfer distance < current>:

Specify second chamfer distance < current>:

If both distances are set to zero, CHAMFER will extend or trim the two lines so they end at the same point.

Angle

Sets the chamfer distances using a chamfer distance for the first line and an angle for the second line.

Specify chamfer length on the first line < current>:

Specify chamfer angle from the first line < current>:

Trim

It controls if the CHAMFER command trims the selected edges to the chamfer line ending points.

Enter trim method [Trim/No trim] < current>:

Method

It controls if CHAMFER command uses two distances or one distance and an angle to create the chamfer.

Enter trim method [Distance/Angle] <current>:

Multiple

Chamfers the edges of more than one set of objects. CHAMFER displays the main prompt and the Select Second Object prompt repeatedly until you press ENTER to end the command.
