Introduction
Sketch fillet and chamfer tools help you smooth or bevel the corners where two lines meet in a sketch. This makes your design look cleaner and prepares it for real-world manufacturing edges.
When you want to round off sharp corners in a mechanical part sketch to reduce stress concentration.
When you need to create a beveled edge on a sketch corner for aesthetic or functional reasons.
When preparing a sketch for extrusion and you want smooth transitions between lines.
When designing parts that require specific edge treatments like rounded or angled corners.
When fixing sharp corners that might cause issues in downstream manufacturing or assembly.
