New Surface Fillet Construction Types

New Construction Types improve the quality of surface fillets and are capable of creating fillets that often fail using previous versions. These include:

• Existing Theoretical, which uses the true theoretical intersection of the input surfaces to build the fillet.
• Build Theoretical, which generates a theoretical intersection of the input surfaces when an existing theoretical intersection is missing.

Note that the Chord Construction Type has now been renamed to Arc (Chord).

Updates to Flow Control options

We've added a new Auto option to the Start, Interior, and End Flow Controls. When set to Auto, Alias determines the best method to use to control the way fillet surfaces edges meet the edges of the boundary surfaces. Creating fillets using Auto takes the guess work out of choosing the Flow Control setting that is most compatible with the edge conditions of your input geometry. This way you get the best results quicker.

For Start and End Flow Control, Alias chooses between Default, Extend, Edge Align, or Connect. For Interior Flow Control, Alias can use different Flow Control methods along the length of the fillet to ensure that the best method is used depending on changes in surface topology.

For more information, see Flow Control.

Improved Interior Flow Control

In addition to Auto, a new User Defined option has been added to the Interior Flow Control. This option gives you greater control over the Flow Control method that's used at each interior boundary of the input surface sets. Select User Defined to view the methods that the Auto setting used to build the fillet. If the desired result is not achieved, use manipulators to choose a different method at each of these areas and quickly rebuild. This workflow lets you easily experiment until you reach the optimal shape and CV layout.
