Fillet Surfaces

Use it!

(3D only) Used to create a 3D fillet between two surfaces (shapes, cones, extruded surfaces, surfaces of revolution, or B-spline surfaces) by sweeping an arc of constant radius along the common intersection curve — commonly referred to as a constant radius rolling ball fillet. The fillet is created in the area pointed to by the surface normals of both surfaces.

Tool Setting	Effect
Truncate	Defines which surface(s) are to be truncated: Both — Both surfaces are trimmed. Single — The first surface identified is trimmed. None — Neither surface is trimmed.
Radius	Sets the fillet's radius.

To place a fillet between two surfaces

1. (Optional) Use the Change Normal Direction tool to set the normal directions for both surfaces.


2. Select the Fillet Surfaces tool.


3. From the Truncate option menu, choose a truncating option.


4. In the Radius field, key in the required radius.


5. Identify the first surface.
   The surface normal orientation displays.


6. Identify the second surface.

7. Accept to view the fillet.

8. Accept to create the fillet.

   Creating a fillet between two surfaces. Left: Identify the two surfaces (1 and 2). Right: Accept (3) to view the fillet, then accept (4) to create the fillet.
