In this section, we will discuss how to apply the chamfer feature. To do this, we will create the model shown in the following drawing:

The preceding drawing specifies two different types of chamfer, each with different specifications. In SOLIDWORKS 2020, there are five different types of chamfer, based on how they are defined. The following table shows each of the different types and what specifies them:

Chamfer Type	Description	Illustration
Angle-distance	This is defined by specifying an angle and the distance that makes up the chamfer. The location of the chamfer is identified by selecting an edge, a face, or multiples of both.
Distance – distance	This is defined by two distances that make up the chamfer. The location of the chamfer is identified by selecting an edge, a face, or multiples of both.
Vertex	This is defined by three distances that move away from a vertex. The location of the chamfer is identified by selecting a vertex.
Offset face	This is defined by an offset distance for the two faces that are adjacent to the chamfer's edge. This gives the chamfer a special definition if the two faces are not perpendicular to each other. The location of the chamfer is identified by selecting one or more edges.
Face – face	This is defined by the distance between two or more faces. The location of the chamfer is defined by selecting the faces that surround the chamfer.

The model we are going to create uses two types of chamfer: angle-distance and vertex. To create the chamfer, we will follow our usual procedure, where we start by planning, then creating sketches, and then applying a feature:

• Planning: Here, we will create a rectangular prism and then create an angle-distance chamfer, followed by two vertex chamfers. 
• Sketch: We will sketch and fully define a 100x100 mm square, as shown in the top view of the drawing at the beginning of this section.
• Feature: We will be applying the extruded boss feature and extruding the square by 50 mm, as shown in the right view of the drawing at the beginning of this section. At this point, we will have the following rectangular prism:

To apply angle-distance chamfers, follow these steps:

1. To apply the chamfer feature, select the Chamfer command, as shown in the following screenshot. The command can also be accessed from the drop-down menu, under the Fillet command:

2. Set up the chamfer's options in the PropertyManager as follows. Some options that are available for the chamfer feature are the same as for the fillet feature, so we won't go over them in as much detail here:

The following is a brief description of the options that we used in this exercise:

• Chamfer Type: From here, we can select one of the five types of chamfer, as specified in the preceding table. We can hover over each one to see their names. For our first chamfer, we will use the angle-distance chamfer.
• Items To Chamfer: This specifies the location of the chamfer. We can move the angle-distance chamfer by selecting Edge 1 (E1), as highlighted in the following rectangular prism. If we select another edge or face by mistake, we can remove it by deleting it from the list here.

• Tangent propagation: This works the same as for fillets. Checking this option will propagate the chamfer across any edges that are tangent to each other. In our case, this option will not make a difference as there are no other edges that have a tangent relationship to our selected edge.
• Full preview/partial preview/no preview: This is similar to the option for fillets. This can determine what our chamfer's preview looks like on the canvas.
• Flip Direction: This will flip the location of the defining angle and distance.
• Distance (D): This value will determine the distance value of our chamfer. In this exercise, the distance is 40 mm.
• Angle (A): This value will determine the angle value of our chamfer. In this exercise, the angle is 30 degrees.

3. While you're here, play around and mix these different options together to understand their effects.
4. Click on the green checkmark to apply the chamfer. After applying the chamfer, we should have the following model:

At this point, our model has one chamfer of the angle-distance type. Now, we will apply the other two chamfers which are vertex types. To apply a vertex chamfer, follow these steps: 

1. Select the Chamfer command from the command bar to apply a second chamfer.
2. Set up the chamfer's options as follows in the PropertyManager:

Here is a brief description of some of the special features we can apply to the vertex chamfer feature:

• Chamfer Type: From here, we select the type of chamfer we want to create; in this case, we want to create a vertex chamfer.
• Items To Chamfer: Select V1 in the canvas to locate the chamfer. Note that, when using the vertex chamfer, we can only apply chamfers one vertex at a time. In other words, we can only select one vertex in Items To Chamfer.
• Equal distance: The vertex chamfer can be defined with three distances that extend away from the vertex into the edges it consists of (refer to the preceding table regarding chamfer types). Checking this option will make all three distances equal, so we only need to input one dimension. If we uncheck this option, we will need to enter three different distances.
• Distance (D): This value will determine the distance of the chamfer. In this exercise, the distance is 35 mm in all three directions.

3. Click on the green checkmark to apply the chamfer. After applying the chamfer, we should have the following model:

4. Now, we can repeat steps 6-8 for V2 to apply the second vertex chamfer. After repeating those steps, we will have the final model. This will look as follows:

This concludes how to apply chamfers. In this section, we discussed the following topics:

• The five different types of chamfer, as well as how are they defined and located
• How to apply different types of chamfer in SOLIDWORKS
• The different options we can use to define chamfers in SOLIDWORKS

At this point, we know how to apply fillets and chamfers. Now let's learn how to modify them.
