Fillet Surfaces

(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 on the side to which the arrow handles point.

You can access this tool from the following:

Ribbon: Modeling > Surfaces > Modify Surfaces > Fillet > Surfaces
Toolbox: Modify Surfaces

Setting	Description
Radius	Sets the fillet's radius.
Truncate	Defines which surface(s) are to be truncated: Both — Both surfaces are trimmed. First — The first surface selected is trimmed. None — Neither surface is trimmed.
Face only	Allows the selection of one face at a time if multiple faces are present in either surface. For example, if a fillet is created between a slab and a surface and this check box is selected, the faces of the slab could be selected. This check box is available only if Truncate is set to None.

Setting

Description

Radius

Sets the fillet's radius.

Truncate

Defines which surface(s) are to be truncated:

Both — Both surfaces are trimmed.
First — The first surface selected is trimmed.
None — Neither surface is trimmed.

Face only

Allows the selection of one face at a time if multiple faces are present in either surface.

For example, if a fillet is created between a slab and a surface and this check box is selected, the faces of the slab could be selected.

This check box is available only if Truncate is set to None.
