How to Use Base Flange in SolidWorks: Step-by-Step Guide
In SolidWorks, use the
Base Flange/Tab feature to create the first sheet metal face by sketching a profile and extruding it with thickness. This feature sets the foundation for building sheet metal parts by defining the base shape and thickness.Syntax
The Base Flange/Tab feature requires a 2D sketch and thickness input. It creates a sheet metal base by extruding the sketch with a specified thickness and bend radius.
- Sketch: Closed 2D profile to define the base shape.
- Thickness: The sheet metal thickness to extrude.
- Bend Radius: Radius for bends at edges.
- Direction: Extrusion direction (one side or both sides).

Base Flange/Tab(Sketch, Thickness, Bend Radius, Direction)
Example
This example shows how to create a simple rectangular base flange with 2mm thickness and 5mm bend radius.
text
1. Open a new part in SolidWorks.<br>2. Select the Front Plane and create a rectangle sketch (100mm x 50mm).<br>3. Exit the sketch.<br>4. Click on <strong>Sheet Metal</strong> tab and select <strong>Base Flange/Tab</strong>.<br>5. Set Thickness to 2mm.<br>6. Set Bend Radius to 5mm.<br>7. Confirm to create the base flange.<br>8. The rectangular sheet metal base is created with specified thickness and bends.
Output
A 3D rectangular sheet metal part with 2mm thickness and 5mm bend radius edges.
Common Pitfalls
- Not closing the sketch profile causes the base flange to fail.
- Using a thickness larger than the sketch size can cause errors.
- Forgetting to select the Sheet Metal tab will hide the Base Flange feature.
- Setting bend radius too small may cause manufacturing issues.
Always verify the sketch is fully closed and the thickness is realistic for your material.

Wrong: Sketch is open or incomplete.<br>Right: Ensure sketch is closed before applying Base Flange.
Quick Reference
| Parameter | Description | Tips |
|---|---|---|
| Sketch | Closed 2D profile | Use simple shapes for base flange |
| Thickness | Sheet metal thickness | Match material specs |
| Bend Radius | Radius of bends | Avoid too small radius |
| Direction | Extrusion direction | Usually one side for base flange |
Key Takeaways
Base Flange/Tab creates the first sheet metal face by extruding a closed sketch with thickness.
Always use a fully closed sketch to avoid errors when creating the base flange.
Set realistic thickness and bend radius values based on your material and manufacturing needs.
Access the Base Flange feature from the Sheet Metal tab in SolidWorks.
The base flange defines the foundation for all further sheet metal features.
