Variable Radius Fillets

Creates a fillet with variable radii values. Use control points to help define the fillet.

Items To Fillet

Some fields that accept numeric input allow you to create an equation by entering = ( equal sign) and selecting global variables, functions, and file properties from a drop-down list. See Direct Input of Equations.
Edges, Faces, Features and Loops Select entities to fillet in the graphics area.
  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.

Variable Radius Parameters

Radius Sets the fillet radius.
Attached Radii Lists the vertices of the edges selected under Items to Fillet for Edges, Faces, Features and Loops , and lists control points you selected in the graphics area.
  Set Unassigned Applies the current Radius to all items that do not have assigned radii under Attached Radii .
  Set All Applies the current Radius to all items under Attached Radii .
Number of Instances Sets the number of control points on the edges.
  Smooth transition Creates a fillet that changes smoothly from one radius to another when matching a fillet edge to the adjacent face.
  Straight transition Creates a fillet that changes from one radius to another linearly without matching edge tangency with an adjacent fillet.

Setback Parameters

These options create a smooth transition between the blended surface, along the edge of the part, into the fillet corner. You select a vertex and a radius, and then assign the same or different setback distances for each edge. The setback distance is the point along each edge at which the fillet starts to blend into the three faces that meet at the common vertex. Example: Setback Fillet Preview
Before setting the Setback Parameters, under Items To Fillet:
  1. Select Multiple radius fillet.
  2. In the graphics area, select three or more edges with a common vertex for Edges, Faces, Features and Loops . You must select all the edges that meet at the common vertex.
Distance Sets the fillet setback distance measured from the vertex.
Setback Vertices Select one or more vertices in the graphics area. The setback fillet edges meet at the selected vertices.
Setback Distances Lists the edge numbers with corresponding setback Distance values. To apply a different setback distance to edges, select an edge in Setback Distances . Then set a Distance and press Enter.
  Set Unassigned Applies the current Distance to all edges that do not have assigned distances under Setback Distances .
  Set All Applies the current Distance to all edges under Setback Distances .

Fillet Options

Select through faces Enables selection of edges through faces that hide edges.
Overflow type Controls the way fillets on single closed edges (circles, splines, ellipses for example) act when they meet edges. Example: Overflow Type. Select one of the following:

Default

The application selects the Keep edge or Keep surface option.

Keep edge

The model edge remains unchanged, while the fillet adjusts.

Keep surface

The fillet edge adjusts to be continuous and smooth, while the model edge changes to match the fillet edge.
