Fillet Flange and Tube Flange now use a new algorithm (the same as in Panel Gap) where the isoparms of the flange are always lined up with those of the fillet (or tube). Consequently, the U Degree for both the flange and fillet (or tube) can be controlled by a single slider. The same is true of Max. Spans.

The control window for these tools has a new section called Surface Structure which groups all the parameters related to the construction of the output surfaces, including Explicit Control options.

The (Length) U Degree, and Max. Spans options apply to both the flange and fillet (or tube) surfaces. The (Section) V Degree only applies to the fillet in Fillet Flange; the V degree of the flange is always 1.
