Description

Fillet or chamfer surface edges with options for conic, G2 continuous, or constant width profiles. Supports variable distance and range limiting.

Select the Edges to fillet or chamfer.
When one or more Edges are selected, the default command, Fillet, is automatically executed.
Alternatively, press the shortcut key B to execute.
Move the yellow dot to specify the distance of the fillet or chamfer.
- Positive movement: results in a fillet.
- Negative movement: results in a chamfer.
Optionally, to select more Edges, Ctrl + click on the Edge. To deselect, Ctrl + click again.
Set the options in the Command Dialog and Keyboard Shortcuts. See Fillet options and Chamfer options below.
Confirm with OK in the Command Dialog or right-click.

Distance:

To fillet an Edge, enter a positive value. To chamfer an Edge, enter a negative value

Tip: To copy a fillet radius, click on the source fillet, but only if the two Distance values are the same and the shape is a Conic.

Shape:

Conic: Produces a natural, smooth transition using a conic section curve.
Chordal: Maintains a constant chord length across the fillet, ensuring visual consistency regardless of the angles being filleted.
G2: Generates a fillet that is curvature continuous with both adjacent surfaces, ideal for complex or high-quality surface work. See Surface Continuity.
Full: Creates a fillet that is tangent to all three neighboring faces (left, center, and right), resulting in a fully rounded shape across the selected face.

Tension:

Use the Tension dialog to control the intensity of the fillet's appearance. This setting applies to all shape types, excluding Full Shape.

Y-Blend:

The “Y-blend” is a special kind of blend or fillet that occurs when three surfaces meet at a common point, forming a “Y” shape. Enabling Attempt, you can create better topology in Y-blend and avoid undesired fillet results.

Selection:

A Chamfer angle: Specify the chamfer angle by moving the cursor, or adjust the two distance values directly.
D Fillet distance: Specify the fillet distance by moving the cursor.
C Chamfer distance: Specify the chamfer distance by moving the cursor.
V Add variable point: Add a variable point to the fillet.
L Add limit point: Click on the fillet centerline to set a range limit. Click again to reverse direction. Up to two limit points can be set. Requires Object Snaps to be enabled.
T Toggle tangent edges: Limit fillets to selected edges only.
Ctrl Modify selection: Add or remove edges from the fillet selection.

Shape:
- Offset: Default chamfer.
- Apex: Reduce the displacement of the border of the chamfer surface.
Others are the same as fillet options.
