What Is Miter Flange in SolidWorks?

A miter flange is a feature in SolidWorks that allows you to create a flange with mitered corners on a sheet metal part. It is useful for creating bends at precise angles and achieving a clean and finished look on your designs.

Creating a Miter Flange

To create a miter flange in SolidWorks, follow these steps:

  1. Create a new sketch: Start by selecting the face or plane where you want to add the miter flange. Then, go to the “Sketch” tab and click on “Sketch” to begin.
  2. Draw the profile: Use sketch tools such as lines, arcs, rectangles, or circles to draw the desired shape of your flange. Make sure that the ends of your profile meet at the corners where you want the mitered edges.
  3. Add dimensions: Apply dimensions to your sketch to define the size and position of your flange. This will ensure accuracy and allow for easy modifications later on.
  4. Select ‘Miter Flange’ feature: Once your sketch is complete, exit out of the sketch mode and go to the “Sheet Metal” tab.

    Click on “Miter Flange” in the features toolbar to activate the command.

  5. Select sketch and set parameters: In the PropertyManager window that appears, choose your sketch as the contour for the miter flange. Specify additional settings such as material thickness, bend radius, relief type, etc., according to your design requirements.
  6. Define corner treatment: Under “Corner Treatment,” select “Mitre” from the drop-down menu. This will ensure that the corners of your flange are mitered at the specified angle.
  7. Click ‘OK’: Once all the parameters are set, click on “OK” to create the miter flange. SolidWorks will generate the desired feature based on your sketch and settings.

Benefits of Miter Flanges

Miter flanges offer several advantages when it comes to sheet metal design and fabrication:

  • Clean and professional appearance: Mitered corners give a polished and finished look to your sheet metal parts, making them visually appealing.
  • Precise angle control: With miter flanges, you have full control over the angle at which your corners bend. This allows for accurate fabrication and ensures that your parts fit together seamlessly.
  • Easier welding: Mitered corners provide better accessibility for welding or joining processes. The clean edges facilitate proper alignment, resulting in stronger and more durable welds.
  • Simplifies manufacturing: By using miter flanges, you can eliminate additional steps like cutting or grinding excess material required for other corner treatments, saving time and reducing manufacturing costs.


The miter flange feature in SolidWorks is a powerful tool for creating precise bends with clean edges on sheet metal parts. By incorporating mitered corners into your designs, you can achieve a professional look while maintaining accuracy and efficiency in manufacturing processes. Experiment with this feature to enhance your sheet metal designs in SolidWorks!
