In both the Freeform Blend and Profile Blend tools, the Side 1 and Side 2 Continuity options now offer G3 Curvature as an additional setting. G3 continuity means that the curvature’s rate of change is the same on either side.

Curvature has been renamed G2 Curvature.

When calculating the blending surface, the V degree is adjusted so that the surface has enough CVs to provide the required continuity on both sides. Degree 7 is needed for G3 Curvature.
