The Variable Blend option is used to blend the edges of a solid with a variable radius. Some of the options in this tab are for the benefit of designers who want non-exact methods of changing the shape of blends. They will be useful for designing parts for which the shape is mostly aesthetic.
NOTE: If a blend operation were to fail, an error dialog appears through which you can elect to create the blend surfaces as sheet bodies. Once this is done, you can use surfacing tools to trim the blend surfaces to the adjacent surfaces of the proposed blend, once modifications have been made to the blend surfaces themselves.
Through this dialog, you are able to specify seven different variable edge blend types. These available types are explained below.
Cross Section Shape
The cross sectional shape options are available for all Variable Radius Edge Blends except Rotated Ellipses. The cross sectional shapes may be varied from circular (the default) to a non-circular spline shape. The default value of 1.0 produces a circular cross section.
NOTE: Thumb weights are entirely for aesthetics. Note that working with thumb weights will require a lot of trial and error. There is no way to get an exact desired shape, only an approximate shape can be obtained. You will need to adjust the numbers until you achieve the results that you desire.
