How to Revolve a Sketch in SolidWorks?

Understanding Revolved Features in SolidWorks

Creating a revolved feature in SolidWorks allows you to design complex shapes efficiently by revolving a 2D sketch around an axis. This technique is essential for producing parts that require rotational symmetry, such as bases, bowls, or any cylindrical components.

Prerequisites for Creating a Revolved Feature

Before you begin, ensure you meet these requirements:

1. Sketch Creation: You need a closed 2D sketch profile representing the shape you wish to revolve.
2. Axis Definition: The axis around which the profile will revolve needs to be defined. This can be established by using an existing line or edge in your model, or by sketching a centerline.

Step-by-Step Guide to Revolve a Sketch

1. Open Your Part: Start by opening the part file where you want to create the revolved feature.

2. Create the Sketch:

   • Select a plane or face to sketch upon by clicking on the desired plane in the Feature Manager.
   • Click on the “Sketch” button to enter sketch mode.
   • Use the drawing tools to create the profile you want to revolve. Ensure the sketch is closed, as an open profile will not work for a revolve feature.

3. Add the Axis of Revolution:

   • Select a line or edge in the sketch that will act as the axis of revolution. Alternatively, you can create a new centerline within your sketch.
   • If you’re creating a centerline, draw it perpendicular to the sketch profile, ensuring it correctly represents the axis around which the profile will revolve.

4. Access the Revolved Tool:

   • Once your sketch is complete with the necessary axis, click on the “Revolved Boss/Base” tool in the Features toolbar. You can also find this option under the “Insert” menu by navigating to “Boss/Base” and then selecting “Revolve.”

5. Configure the Revolve Options:

   • The Revolve Property Manager will open. Here, select the sketch profile that you set up earlier for revolution.
   • Define the angle for revolution. By default, it is set to a full 360 degrees, but you can customize this value to create a partial revolution if desired.
   • Verify that the axis of revolution is correctly identified; it should align with the centerline or edge you designated earlier.
6. Finalize the Feature:
   • Review the preview displayed in the Property Manager to ensure the feature will appear as intended.
   • Click the “OK” button to complete the operation. The system will generate the revolved feature based on your sketch and specified parameters.

Modifying and Editing Revolved Features

Revolved features can be modified post-creation. If you need to adjust the sketch:

1. Edit the Sketch: Right-click on the sketch in the Feature Manager and select “Edit Sketch.” Make your necessary changes, then exit the sketch.

2. Update the Feature: The revolved feature should automatically update to reflect the latest changes made in the sketch.

Frequently Asked Questions

1. Can I use an open profile for a revolve feature in SolidWorks?
No, a revolve feature requires a closed profile. An open sketch will not produce the desired solid or surface result.

2. Is it possible to revolve a sketch around an existing model geometry?
Yes, you can select an existing edge or line as the axis of revolution, allowing for versatile design options around existing features.

3. What types of shapes can I create using the revolve feature?
The revolve feature can create various shapes, including cylinders, cones, and other axisymmetric forms, depending on the 2D sketch profile used for revolution.
