How Do You Make a Spur Gear in SolidWorks?

Are you interested in learning how to create a spur gear using SolidWorks? Look no further!

In this tutorial, we will guide you through the step-by-step process of designing a spur gear in SolidWorks. By the end of this article, you will have a solid understanding of how to utilize this powerful software to create your own gears.

Step 1: Launching SolidWorks

To get started, open SolidWorks on your computer. If you don’t have it installed, make sure to download and install the software from the official website.

Step 2: Creating a New Part

Once SolidWorks is up and running, click on “New” to create a new part. You can also use the shortcut Ctrl + N. This will open a blank canvas where you can begin your gear design.

Step 2.1: Setting Units

Before proceeding further, it’s important to set your desired units for the part. To do this, go to “Options” in the top menu bar and select “Document Properties.” In the “Units” tab, choose your preferred unit system (e.g., millimeters or inches).

Step 3: Sketching the Gear Profile

To create a spur gear, we need to sketch its profile first. Select the “Sketch” option from the top toolbar or use the shortcut S key.

Step 3.1: Drawing a Circle

In the sketch mode, choose either “Front Plane” or “Top Plane” as your sketching plane from the feature tree on the left side of your screen. Click on “Circle” in the sketch toolbar and draw a circle representing the base diameter of your gear.

Note: Make sure to dimension your circle by selecting the “Smart Dimension” tool from the sketch toolbar. This will ensure that your gear has accurate dimensions.2: Adding Teeth to the Gear Profile

To add teeth to your gear, click on “Smart Dimension” again and specify the number of teeth you want for your gear. Additionally, you can add a pitch diameter by drawing another circle concentric with the base circle.

Step 4: Extruding the Gear

Now that we have our gear profile sketched, it’s time to extrude it into a 3D model. Click on “Exit Sketch” to exit sketch mode.

Step 4.1: Selecting the Sketch

In order to extrude our sketch, we need to select it first. From the feature tree on the left side of your screen, locate and click on your sketch.2: Extruding the Sketch

With your sketch selected, go to “Features” in the top toolbar and click on “Extruded Boss/Base.” In the dialog box that appears, enter the desired thickness for your gear and hit “OK.”

Step 5: Finishing Touches

Congratulations! You have successfully created a spur gear in SolidWorks.

However, there are a few additional steps you can take to enhance its appearance.

Step 5.1: Adding Fillets

To make your gear look more realistic, you can add fillets to smooth out its edges. Click on “Fillet” in the top toolbar and select any sharp edges you want to round off.2: Applying Material and Texture

Lastly, you can apply a material and texture to your gear to make it visually appealing. Right-click on your gear in the feature tree, select “Appearance,” and choose the desired material and texture from the provided options.

Note: You can also create your own custom materials and textures by clicking on “Edit Appearance” in the appearance menu.


In conclusion, designing a spur gear in SolidWorks is a straightforward process that involves sketching the gear profile, extruding it into a 3D model, and applying finishing touches like fillets and materials. By following this step-by-step tutorial, you should now have the necessary knowledge to create your own gears using SolidWorks.

  • Remember to save your work regularly to avoid losing any progress.
  • Experiment with different parameters and dimensions to create gears of varying sizes and specifications.
  • Explore other features of SolidWorks, such as assemblies and animations, to take your design skills to the next level.

We hope this tutorial has been helpful in expanding your SolidWorks expertise! Happy gear designing!
