Face Fillets

Blends non-adjacent, non-continuous faces.

Face Set 1 and Face Set 2 selected Face fillet applied

Items To Fillet

Radius Sets the fillet radius.
Face Set 1 Select the first face or set of faces in the graphics area to blend.
Face Set 2 Select the faces in the graphics area to blend with Face Set 1.
If you select more than one face for either Face Set 1 or Face Set 2, each set of faces must be smoothly connected for the face fillet to properly propagate to all faces.
  Tangent propagation Extends the fillet to all faces that are tangent to the selected face. Example: Tangent Propagation
  Full preview Displays a fillet preview of all edges.
  Partial preview Displays a fillet preview of one edge only. Press the A key to view each fillet preview in turn.
  No Preview Improves rebuild time with complex models.

Fillet Options

Select through faces Enables selection of edges through faces that hide edges.
Hold line Select an edge on the part or a projected split line on a face as a boundary that determines the face fillet shape. The radius of the fillet is driven by the distance between the hold line and the edge to fillet.

Curvature continuous Resolves discontinuity problems and creates a smoother curvature between adjacent surfaces. To verify the effect of the curvature continuity, you can display Zebra Stripes. You can also analyze the curvature using the curvature tool.

Curvature continuous fillets differ from standard fillets. They have a spline cross section as opposed to a circular cross section. Curvature continuous fillets are smoother than standard fillets because there is no jump in curvature at the boundary. Standard fillets include a jump at the boundary because they are tangent continuous at the boundary.

Constant width Creates a fillet with a constant width.

Help point Resolves an ambiguous selection when it may not be clear where the face blend should occur. Click in Help Point Vertex, then click a vertex on the side where you want the face fillet. A fillet is created at the location closer to the Help point.
Trim Surfaces (Surfaces only) Select one of the following:

Trim and attach

Trims the filleted faces and knits the surfaces into one surface body.

Don't trim or attach

Adds a new fillet surface, but does not trim the faces or knit the surfaces.
