Fillet feature on edges in Solidworks - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the Fillet feature on edges in SolidWorks?

The Fillet feature rounds off sharp edges on a 3D model to improve aesthetics, reduce stress concentration, and make parts safer to handle.

beginner

Which types of edges can you apply a Fillet to in SolidWorks?

You can apply a Fillet to straight edges, curved edges, and edges where two faces meet at an angle.

intermediate

What is the difference between a Constant Radius Fillet and a Variable Radius Fillet?

A Constant Radius Fillet uses the same radius along the entire edge, while a Variable Radius Fillet allows the radius to change along the edge.

intermediate

How does applying a Fillet affect the strength of a part?

Applying a Fillet reduces stress concentration by smoothing sharp corners, which can increase the part's strength and durability.

beginner

What is a common mistake when applying Fillets on edges?

A common mistake is applying too large a radius that causes geometry errors or overlaps with other features, making the model invalid.

What does the Fillet feature do to edges in SolidWorks?

A Deletes edges

B Sharpens edges

C Rounds sharp edges

D Colors edges

The Fillet feature rounds sharp edges to make the part smoother and safer.

Which Fillet type allows the radius to change along the edge?

A Variable Radius Fillet

B Constant Radius Fillet

C Face Fillet

D Full Round Fillet

Variable Radius Fillet lets you set different radii at different points along the edge.

Why is it important not to use too large a Fillet radius?

A It deletes the part

B It makes the part heavier

C It changes the color

D It can cause geometry errors

Too large a radius can cause overlaps or invalid geometry in the model.

Applying Fillets can improve part strength by:

A Reducing stress concentration

B Adding weight

C Increasing sharp corners

D Removing material

Fillets smooth sharp corners, reducing stress concentration and improving strength.

Which edges can you apply a Fillet to?

A Only curved edges

B Straight, curved, and angled edges

C Only straight edges

D Only edges on flat faces

Fillets can be applied to straight, curved, and edges where two faces meet at an angle.

Explain in simple terms what a Fillet feature does on edges in SolidWorks and why it is useful.

Think about how smoothing corners helps in real life.

Describe the difference between Constant Radius and Variable Radius Fillets and when you might use each.

Imagine a smooth curve that changes shape versus one that stays the same.
