Editable tween curve on surface or polysurface

1 0 Beginner
History in Rhino 7 must be turned on, in order for the modifications on the input surfaces to affect the output tween surface and its corresponding curve intersection. The latter could be further simplified via the "! _RemoveMultiKnot" command, though that will destroy the history and also may cause the curve to no longer sit perfectly accurate on the surface/polysurface.

Loft to simulate a full round fillet between 3 surfaces

1 0 Beginner
In cases where 3 surfaces meet together and the goal is to create a full round fillet in-between, the top surface could be used to extract an isocurve that’s then used as a middle profile for a “Loft surface”. The two main vertical surfaces are shortened by the amount of approximate radius (in this example, the radius is 5 mm, because the two main surfaces are 10 mm far from each other) and set to tangent start and end for the loft operation. That would maintain the desired top limit for the rounded surface, though it will not produce a true radius fillet.

This was something we did to explain to a friend how a designer had made a kind of transitional cover from one mouth to two. We made these images to help her understand. I think it will also be useful for many people.
