Hi Burr, that's great, I hope the blend update will be useful too!

Sorry I'm not quite sure what the question is exactly.... The blend surface is G2 where it touches the other surface, not C2, but usually what people are interested in is G1 or G2 which refers to continuity of geometric properties like tangent and curvature values. C1 and C2 means not only geometric continuity but also parametric continuity where basically some of the other underlying mathematical properties are equal at the juncture point. That's only really of interest to people doing pretty specialized things though.
