Elliptical Fillet Feature
Insert 
Fillet/Chamfer (Part Level)
Use this command to create an elliptical fillet
features. Similar to the Asymmetric Chamfer command,
this command uses setback and angle options to define the size of the
elliptical cross-section of the fillet.
The required inputs include the edges to fillet and the first
and second setback distance (or first setback and angle if the Angle
option is used, see below). Optionally, you can specify the conic ratio
and use patch faces in tight corners. See also Partial Results Filleting on the CAD Tips & Techniques page.
Edges - Select the edges to fillet.
Setback - Specify the first setback distance. This distance along with the second setback (setback2) or Angle if selected will determine the size of the elliptical fillet. Use the Conic ratio option to determine the elliptical shape.
Angle
Setback - This option determines the method used to define the
size of the elliptical fillet cross-section. Select from the following.
Angle - This option uses the first setback distance along with
an angle to determine the size of the cross-section. Use the Angle
option below to enter the angle.
Setback - This option uses the first setback distance along with
a second setback to determine the size of the cross-section. Enter the
second offset value using the Setback2 option below.
Angle - Specifies the angle from the first setback distance to determine the size of the elliptical fillet cross-section.
Setback2 - Specifies the second setback distance to determine the size of the elliptical fillet cross-section.
Conic ratio - Enter the conic ratio within the range of 0 - 1. (default = 0.5). See Conic Bi Rail Face for more information about conic ratios.
Use patch for tight corners - Check this box to allow patch faces to be used in tight corners.
Pressing the <SHIFT> key while selecting edges initiates a chain pick. Curves and edges that are connected end to end are selected.
