Create Fillet Surface

Model > 3D Power Pack

Ctrl+Alt+Y (Windows)

Cmd+Option+Y (Mac)

The Create Fillet Surface command creates a surface between two selected surfaces, trimming the original surfaces by default.

This command is useful for sheet metal design (for example, for car bodies) to provide a smooth transition between two adjacent surfaces—perhaps for aesthetic quality or because of a manufacturing requirement.

To create a fillet surface at the intersection of two selected NURBS surfaces:

Select two NURBS surfaces. The position of the fillet surface depends on the normal of the NURBS surfaces; select Show Normal from the Object Info palette to display the surface normals.

Select the command.

The Fillet Surface Preferences dialog box opens. Enter the desired Fillet Radius, and then select the trim and cross section type for the fillet.

The following trim type examples use a circular cross section type, and the cross section examples use an edge tangency trim type. The original surfaces are trimmed.

Parameter

Description

Fillet Radius

Specifies the radius of the fillet surface

Trim Type

 

Edge Tangency

Creates a blend between the minimal and maximal intersections on each end of the fillet

Minimal

Trims the fillet surface to the minimal intersecting areas on the face boundaries

Fillet_min.png 

Maximal

Trims the fillet surface to the maximal intersecting areas on the face boundaries

Fillet_max.png 

None

Generates the entire fillet without trimming the fillet surface

Cross Section Type

 

Circular

Creates a fillet surface with a circular cross section

 

Linear

Creates a fillet surface with a linear cross section

Tangent Continuous Blend

Creates a fillet surface with a tangent continuous G1 cross section

Curvature Continuous Blend

Creates a fillet surface with a curvature continuous G2 cross section

Trim Original Surfaces

Creates a fillet surface and trims the original surfaces where they connect to the fillet surface

A NURBS fillet surface is created between the two objects.

The position of the fillet surface depends on the surface normals. The fillet is created differently if the Reverse Normal button is clicked for one or both of the surfaces from the Object Info palette.
