How Do You Make a Spring Flexible in SolidWorks?

Are you looking to make a spring flexible in SolidWorks? Look no further! In this tutorial, we will guide you through the process of creating a flexible spring using SolidWorks’ powerful features.

Step 1: Creating the Sketch

First, we need to create a sketch that represents the cross-section of our spring. Start by selecting the plane where you want to create the sketch. Then, use the sketch tools to draw a closed profile that represents one coil of the spring.

Note: It’s important to ensure that your sketch is properly dimensioned and constrained for accurate results.

Step 2: Extruding the Profile

Once you have created the sketch, it’s time to extrude it into a 3D shape. Select the sketch and choose the “Extrude” tool from the toolbar. In the extrude dialog box, specify the desired length or height of your spring.


  • To make your spring flexible, check the “Thin Feature” option in the extrude dialog box. This will create a thin-walled body instead of a solid object.
  • You can also control other parameters such as draft angle, taper, and end conditions to customize your spring’s shape.

Step 3: Adding Flexibility

To make our spring flexible, we will utilize SolidWorks’ “Flex” feature. Select the face or faces of your spring that you want to make flexible. Then, go to “Insert” > “Features” > “Flex”.

In the flex dialog box, choose “Bend” as the type of deformation and specify an angle or radius for the bend. You can experiment with different values to achieve the desired flexibility.

Note: SolidWorks’ Flex feature allows you to apply various types of deformations, such as twist, taper, and stretch. Feel free to explore these options for more advanced flexibility.

Step 4: Fine-tuning the Flexibility

If you want to further refine the flexibility of your spring, you can use SolidWorks’ “Motion Study” feature. This feature allows you to simulate the movement and deformation of your model.

Start by creating a new motion study and defining the desired constraints and forces acting on your spring. Then, run the simulation and observe how your spring flexes under different conditions.


  • You can animate the motion study by adjusting the timeline settings. This will help you visualize how your spring behaves in real-life scenarios.
  • Try experimenting with different forces, constraints, and movement patterns to explore various possibilities for your flexible spring design.


Congratulations! You have successfully learned how to create a flexible spring in SolidWorks. By following these steps and utilizing SolidWorks’ powerful features like sketching, extruding, flexing, and motion studies, you can now design springs that accurately represent their real-life behavior.

Remember to always experiment and iterate on your designs to achieve optimal results. Happy designing!
