The revolved boss feature adds materials by revolving a sketch around an axis of revolution. To show you how to apply the revolved boss feature, we will create the following model. Now that we are using more and more features, we will start to notice that we use the same options repeatedly. For example, when applying the revolved boss, we notice that most options are the same ones that we use while applying extruded boss. Therefore, we won't explain these again here:

As usual, we will follow our standard procedure planning, sketching, and applying features:

• Planning: Here, we'll draw the profile shown in the right view of the preceding drawing, and then we'll rotate that by 180 degrees.
• Sketching: Here, we're going to sketch the profile highlighted in the Right View using the right plane. This includes using the axis of revolution. Our sketch should look as follows:

• Applying the feature: Here, we are going to apply our revolved boss feature.

To apply the revolved boss feature, follow these steps: 

1. Select the Revolved Boss/Base command from the Features command bar. We don't need to exit the sketch to select the command. However, if we do exit the sketch for whatever reason, we can select the Revolved Boss/Base command and then select the sketch we want to apply it to:

2. Adjust the options in the PropertyManager, as shown in the following screenshot:

Here is a brief description of the unique options that can be used with the revolved feature:

• Axis of Revolution: This can be any straight line located on the canvas. This axis will be used to apply the feature by rotating the sketch around that axis. In our exercise, we will select the centerline indicated in the preceding diagram as the axis of revolution.
• End Condition: This provides a few options regarding how the revolution will stop. In this exercise, we will use the Blind condition. By doing this, we will decide on the end of the revolution by determining the angle of rotation.
• Reverse Direction: This is the two curved arrows next to the end condition field. Clicking on this icon will reverse the rotation direction of the revolved boss. 
• Angle (A1): This determines when the revolution stops. In this exercise, the revolution will stop at 180 degrees.

3. Since we're setting the feature's options, we will be able to see a preview of the feature on the canvas. This will look as follows:

The rest of the options (Direction 2, Thin Feature, and Selected Contours) were explained when we look at the extruded boss feature. They have the same functionality.

4. To apply the revolved boss feature, we can click on the green checkmark at the top of the Options panel. The resulting model should look as follows:

This concludes how to use the revolved boss feature. In this section, we discussed the following topics:

• How to apply the revolved boss/base feature
• The different options we can use to define the revolved boss/base feature

Now, we can start learning about the revolved cut feature.
