Five Fantastic Fillet Facts in Fusion
Five Fantastic Things About Fillets in Fusion (formerly known as Fusion 360)
Fillets are one of the most versatile tools in Fusion, offering both aesthetic and functional benefits. From smoothing sharp edges to improving part durability, understanding how to use fillets effectively can elevate your designs. This blog covers five fantastic things about fillets and how they can enhance your workflow. For a detailed step-by-step video tutorial, scroll to the end of this post. Whether you're a student or a beginner, this free Fusion tutorial will guide you through these exciting examples.
1. Full Round Fillets for Seamless Iterations
Full Round Fillets automatically adjust to changes in your model geometry, making them perfect for designs that undergo multiple iterations. This feature ensures your workflow remains efficient and smooth as your design evolves.
Here’s why they’re fantastic:
They adapt automatically to changes, saving time during design revisions.
Ideal for creating professional-grade, flexible models.
To apply a Full Round Fillet:
Select the edges you want to round.
Choose the "Full Round Fillet" option in the Fillet tool menu.
Adjust the parameters if needed, and Fusion will automatically adapt to geometry changes as you refine your model.
2. Variable Fillets for Custom Designs
Variable Fillets allow you to adjust the radius along an edge, making them ideal for organic designs or parts requiring varying curves. This feature is especially useful for aesthetic or functional purposes.
Here’s why they’re fantastic:
Perfect for organic or ergonomic designs.
Add personality and uniqueness to your models.
To create a Variable Fillet:
Open the Fillet tool and select the edge you want to modify.
Add multiple points along the edge where the radius will vary.
Adjust the radius at each point to craft intricate, custom geometry.
Pro Tip: Use Variable Fillets to transition between different shapes smoothly or to achieve a unique design style.
3. Fillets for 3D Bodies and 2D Sketches
Fillets in Fusion aren’t limited to 3D models—you can also use them in 2D sketches. Each application serves different stages of the design process:
Here’s why they’re fantastic:
3D Bodies: Apply fillets to smooth edges after modeling. This is particularly useful for creating ergonomic designs or reducing sharp transitions.
2D Sketches: Round corners before extruding. This approach can simplify the modeling process and maintain consistency in your design.
To apply a fillet:
Select the edges or corners you want to round.
Specify the desired radius.
Preview and apply the changes.
4. Fillets for Strength and Durability
Fillets aren’t just about looks. They play a crucial role in reducing stress concentrations at sharp edges, which can improve the durability, strength, and longevity of your parts.
Here’s why they’re fantastic:
Make parts more resistant to mechanical stress.
Increase the reliability and lifespan of your designs.
For designs subject to mechanical stress, adding fillets is a smart way to increase reliability.
5. Advanced Fillet Options in Fusion
Fusion offers a range of fillet types, radius settings, and corner styles to suit your design needs.
Here’s why they’re fantastic:
Selection Sets: Apply fillets to multiple edges simultaneously for consistent results.
Curvature Options: Choose from G1 or G2 settings:
G1 (Tangent): Ensures smooth tangency with a slight curvature change.
G2 (Curvature Continuity): Provides smooth, consistent curvature for a polished look.
Corner Styles: Customize how fillets interact at intersecting edges for precise control.
Experiment with these options to discover the best settings for your project.
Wrap-Up
Fillets in Fusion are incredibly versatile, offering both aesthetic and functional benefits.
