I am really loving the new Style Spline, pleasently surprised that you can dial up the degree to as high as you want, too!

However I am confused... if this is intended to serve as a single-span construction tool, what happens when you make a Boundary Surface from two style splines? As you can see from the curvature combs the resultant surface is not as smooth as it should be. There are no controls to make the surfaces resulting from Style Splines to be single-span as well.

Does this happen automatically or does SolidWorks insert spans in this Boundary Surface, resulting in the kind in the curvature plot?
