How Do You Make an Airfoil in SolidWorks?

Creating an airfoil in SolidWorks can seem like a daunting task, but with the right approach and a little bit of practice, it can be accomplished easily. In this tutorial, we will guide you through the process of making an airfoil in SolidWorks step by step.

Step 1: Sketching the Airfoil Profile

To start with, create a new sketch on the desired plane where you want to create the airfoil. Use the Sketch tools to draw the profile of the airfoil. Remember that an airfoil typically has a curved upper surface and a flatter lower surface.


  • Use splines: For smoother and more precise curves, try using splines instead of regular lines.
  • Reference dimensions: If you have specific dimensions for your airfoil, make use of reference dimensions to ensure accuracy.

Step 2: Lofting the Airfoil Shape

Once you have sketched the profile of your airfoil, it’s time to loft it into a solid shape. Select the Loft feature from the toolbar and choose the profiles you created in Step 1 as your guide curves.


  • Add guide curves: If your airfoil has complex shapes or variations along its length, consider adding guide curves to control the lofting process more precisely.
  • Tweak parameters: Experiment with different lofting parameters such as tangency and curvature controls to achieve the desired shape.

Step 3: Adding Thickness

An airfoil is not just a two-dimensional shape; it also has thickness. To add thickness to your airfoil, use the Thicken feature. Select the surface created from lofting and specify the desired thickness value.


  • Uniform thickness: If your airfoil has a constant thickness throughout, set the same value for both sides of the surface.
  • Varying thickness: If your airfoil has varying thickness along its length, consider using different values for different sections.

Step 4: Filleting and Smoothing

To ensure that your airfoil has smooth transitions between surfaces, use the Fillet feature. Select any sharp edges or corners that need to be rounded off and apply a fillet of appropriate radius.


  • Variable fillet radius: If your airfoil has varying fillet radii along its length, consider using multiple Fillet features with different radii.
  • Blend surfaces: In some cases, you may need to create blends between surfaces to achieve smoother transitions.

Step 5: Finishing Touches

Now that you have created the basic shape of your airfoil, it’s time to add any additional features or details. This could include things like control surfaces, mounting points, or any other design elements specific to your project.


  • Create separate sketches: Use separate sketches for adding additional features to keep your design organized and easier to modify later on.
  • Edit feature order: If needed, you can edit the order of the features in the Feature Manager Design Tree to make adjustments or changes.

By following these steps and incorporating your own creativity, you can create a custom airfoil in SolidWorks. Remember to save your work regularly and experiment with different techniques to achieve the desired results. Happy designing!
