How Do You Make a Revolved Boss Base in SolidWorks?

In SolidWorks, creating a revolved boss base is a common operation used to generate complex 3D shapes by revolving a sketch around an axis. This feature is particularly useful for creating objects with rotational symmetry, such as bottles, vases, or screws.

Step 1: Create a Sketch

To start, open your SolidWorks project and navigate to the desired part or assembly file. Begin by selecting the plane on which you want to create the revolved boss base. For example, choose the Front Plane.

Next, click on the Sketch icon from the toolbar or go to Insert > Sketch. This will activate the sketching environment.

Step 2: Draw Your Profile

In this step, you will draw the outline of your shape that will be revolved. Use various sketch tools such as lines, arcs, circles, and splines to create your desired profile.

Note: Ensure that your sketch is fully closed and free from any self-intersections or overlapping entities. This will help avoid issues during the revolve operation.

Tips:

  • Use Construction Geometry: If needed, you can utilize construction lines or points to aid in creating symmetrical sketches.
  • Add Dimensions: Applying dimensions to your sketch entities will make it easier to control their sizes and proportions.
  • Add Relations: Applying relations between sketch entities can help maintain their intended relationships even if dimensions change later on.

Step 3: Define Axis of Revolution

Now, you need to define the axis around which the sketch will be revolved. To do this, click on the Centerline tool from the Sketch toolbar and draw a centerline that passes through the origin of your sketch or any other desired point.

Tips:

  • Existing Geometry: If you have existing geometry that aligns with your desired axis, you can also select it instead of drawing a centerline.
  • Mirror Feature: If your object has symmetry, you can create half of the sketch and mirror it later to save time.

Step 4: Revolve the Sketch

With your sketch and axis defined, it’s time to perform the revolve operation. Go to Features > Revolved Boss/Base, or click on the corresponding icon in the Features toolbar. This will open the Revolve PropertyManager.

In this PropertyManager, select your sketch as the profile to be revolved and choose the axis of revolution. You can also define additional parameters such as angle of revolution and direction of rotation if required.

Make sure to preview your revolve by clicking on the Preview button, ensuring that everything looks as expected before finalizing the operation.

Tips:

  • Selecting Multiple Profiles: If you have multiple closed profiles in one sketch, you can select them all for a single revolve operation. SolidWorks will recognize each closed loop individually.
  • Varying Cross-Sections: You can also create varying cross-sections along the axis by using multiple sketches or sketch segments.

Once you are satisfied with the preview, click OK to complete the revolve operation. Your revolved boss base will now be created as a feature in your SolidWorks model.

Congratulations! You have successfully learned how to make a revolved boss base in SolidWorks. This powerful feature allows you to create complex 3D shapes with ease, adding depth and realism to your designs.
