CAD system has provided Fillet and Chamfer command to help designers work on the small angles or intersections of spare part and equipment, which are very common in mechanical design.
1.Firstly, click on the Chamfer button, as shown in the following picture,
or enter CHA, then press Enter to use the Chamfer command, as shown in the following picture,
2. Pay attention to the command line and we can see that CAD provides several methods for Chamfer, as shown in the following picture,
Here we enter D (Distance) and press Enter, which is the most commonly used Chamfer method. As for other option, beginners could explore themselves.
3. The system would prompt to specify the Chamfer distance of the first and second objects. This distance starts from the intersection and is the distance after the Chamfer, as shown in the following picture,
Normally, the two distances are the same. If we have know the distance and angle, we can enter A option at the second step.
4. After the setup of the Chamfer distance, select 1 and 2 to complete the Chamfer, as shown in the following picture, and you can also Chamfer 3 and 4 using the same method.
From the command line prompts at the second step, we can see that there is a option M (Multiple), if we enter M and press Enter, we’’ be able to continuously chamfer several objects.
1.Click “Fillet” button, as shown in the following picture,
or enter F, then press Enter to use the Fillet command.
There are two options in the command line that we should pay close attention to: R (Radius) and M (Multiple). “R” is very easy to understand, it’s the radius for the Fillet; if we choose M, them we can continuously do the Fillet command, otherwise the system will only do Fillet once, which is set by default.
2. Enter R and press Enter, the CAD prompts to specify fillet radius, as shown in the following picture,
Here we enter “1” and then press Enter.
3. Select line 1 and 2 one by one, the CAD system would automatically work on the intersection of the two lines. The final effect is shown in the following picture,
If we’ve selected “M” at step 2, we will get several continuous Fillet.
Unlike Trim or Extend, Fillet and Chamfer apply not only to 2D lines but also 3D solid, so in many cases, Fillet and Chamfer may replace Trim or Extend command.
