Fillet
Round edges with a specified radius
Keyboard shortcut: F
Overview
The Fillet tool rounds sharp edges with a smooth curved surface. Select a face to fillet all its boundary edges, or Shift+click to select multiple faces. Variable radius fillets allow different radii at each end of an edge.
Parameters
| Parameter | Description | Default |
|---|---|---|
| Radius | The fillet radius | 0.125 in |
| Variable Radius | Use different radii at start and end of edges | Off |
| End Radius | Radius at the end of edges (variable mode only) | 0.125 in |
How to Use
1
Click a face
Click on a face to select all its boundary edges for filleting.
2
Add more faces (optional)
Hold Shift and click additional faces to include their edges.
3

Natural Language Alternatives
Instead of using the tool, you can type these commands:
Fillet all edges with 0.125 inch radiusAdd 3mm fillets to the top edgesRound the external edges with 1/4 inch radiusFillet Face 2 and Face 3 with 1/8 inch radius
Tips
- Click a face to select all edges around it at once
- Apply fillets after other operations like holes and bosses
- Smaller radii work better on internal corners
