How Do You Make a Lip and Groove in SolidWorks?

In this tutorial, we will learn how to create a lip and groove feature in SolidWorks. A lip and groove is a commonly used feature in engineering design, especially in sheet metal fabrication. It allows for easy assembly and provides a secure connection between two parts.

Step 1: Create a New Part

To begin, open SolidWorks and create a new part by clicking on File > New > Part.

Step 2: Sketch the Profile

In this step, we will sketch the profile of the lip and groove. Select the desired plane to sketch on by clicking on Front Plane, Top Plane, or Right Plane.

Use the available sketch tools to create your desired profile. You can use lines, arcs, rectangles, or any other sketching tool of your choice.

Note: It is important to ensure that the dimensions of the profile are accurate as they will determine the final dimensions of the lip and groove.

Step 3: Extrude the Profile

Once you have sketched the profile, it’s time to extrude it into a 3D solid. Click on Extruded Boss/Base from the toolbar or navigate through Insert > Boss/Base > Extrude..

In the Extrude PropertyManager, select your sketch as the contour to extrude. Set the distance for both the lip and groove according to your requirements.

Ensure that you select Add material. Click on OK.

Step 4: Add Fillets (Optional)

If you want to add fillets to the lip and groove, you can do so by clicking on Fillet from the toolbar or navigating through Insert > Features > Fillet.

Select the edges that need to be filleted and set the desired radius.

Step 5: Save and Export

Congratulations! You have successfully created a lip and groove feature in SolidWorks.

Remember to save your part by clicking on File > Save. You can also export it in various formats such as STEP, IGES, or STL for further use or manufacturing.


  • Dimension Everything: Make sure to dimension all your sketches accurately to avoid any discrepancies in the final part.
  • Experiment with Profiles: Try different profiles for your lip and groove feature to achieve the desired functionality and aesthetics.
  • Maintain Design Intent: Keep in mind the purpose of the lip and groove while designing it. Ensure that it serves its intended function effectively.
  • Test Your Design: Before implementing your lip and groove design into production, create prototypes or perform simulations to validate its performance.

You are now equipped with the knowledge of creating a lip and groove feature in SolidWorks. Use this feature wisely in your designs to enhance assembly processes and provide robust connections between parts.

Note: This tutorial assumes that you have a basic understanding of SolidWorks and its user interface. If you are new to SolidWorks, consider going through introductory tutorials to familiarize yourself with the software.
