Hello dailyautocad readers,

Today, I will continue my series of articles about solid modeling. Today’s topic is to make chamfer at the corners of 3 dimensional entities. Just like FILLET command, using CHAMFER command in 3 dimensional environment is very easy. Only difference will be one additional question that AutoCAD will prompt during the execution of the command. And, this is all because of the structure of the command.

Fig.1

Command: chamfer

(TRIM mode) Current chamfer Dist1 = 0.0, Dist2 = 0.0
Select first line or [Undo/Polyline/Distance/Angle/Trim/mEthod/Multiple]:
Base surface selection…
Enter surface selection option [Next/OK (current)] <OK>: OK

Specify base surface chamfer distance: 5

Specify other surface chamfer distance <5.0>: 10
Select an edge or [Loop]: Select an edge or [Loop]:

Execution of the command is given above by an example. Let’s examine the flow of this execution step by step:

(TRIM mode) Current chamfer Dist1 = 0.0, Dist2 = 0.0
Select first line or [Undo/Polyline/Distance/Angle/Trim/mEthod/Multiple]:

First of all, AutoCAD outputs a line that includes current settings of CHAMFER command and prompts us to select the first line for which chamfering will be made. At this point, if we point to an edge of a 3 dimensional solid, then a surface which belongs to the line that we select is highlighted and the flow of the command changes as follows:

Base surface selection…
Enter surface selection option [Next/OK (current)] <OK>: OK

At this stage, you are prompted to select the first surface that belongs to the edge that you would like to make chamfering on. You must select “OK”, if the surface is selected properly. If not, you can select the other available surfaces by pressing “NEXT”. In our example, the first surface is the surface that is numbered as 1.

Specify base surface chamfer distance: 5

Specify other surface chamfer distance <5.0>: 10
Select an edge or [Loop]: Select an edge or [Loop]:

Fig.2 (from AutoCAD 2008 help file)

Now, the command is asking us the distances 1 and 2. In our example, the first distance is 5 and the second one is 10. Once the edge is selected than chamfering is done (Fig. 1).

Here are the other options of command:

Fig.3 (from AutoCAD 2008 help file)

By using edge option, chamfering is made equally for the edge that you select.

Fig.4 (from AutoCAD 2008 help file)

Another option ‘Edge loop’ is that, you can make chamfer for all of the edges that belongs to the same surface.

Fig. 2,3 and 4 was taken from help files of AutoCAD 2008.

Have a nice day.
