You can dimension chamfers in drawings. In addition to the usual dimension display properties, chamfer dimensions have their own options for leader display, text display, and X display. X display is the size of the X in a chamfer dimension with two numbers, such as 1 X 45° (Length X Angle), 45° X 1 (Angle X Length), 1 X 1 (Length X Length) or C1 (chamfers of 45°).
Tolerance types for chamfer dimensions are
limited to None, Bilateral,
and Symmetric.
You can set document default for chamfer dimension leader display, text display, and X display in Tools, Options, Document Properties, Dimensions, Leaders.
To insert chamfer dimensions into a drawing:
Click Chamfer Dimension
on the Dimensions/Relations toolbar or click Tools, Dimensions,
Chamfer.
The pointer changes to 
.
Select the chamfered edge, select one of the lead-in edges, then click in the graphics area to place the dimension.

edge first. However, the dimension does not appear until you subsequently
select one of the lead-in edges.
The Dimension PropertyManager appears, and the tool remains active for you to dimension other chamfers.

to close the Dimension
PropertyManager.
