Two simple single span degree 2 x degree 3 surfaces, mirrored with perfect G2 continuity.
MergeSrf with Smooth=Yes Roundness=1 results in a 3 span degree 1 x 1 span degree 3 surface.
I assume this is not the intended result.

Hi David - degree stays 2 here -
MakeUniform will make it a little less angly.
@pascal My mistake - it stay degree 2.
It is counter intuitive that Smooth=1 results in an almost angular shape and Smooth=0 results in a the expected smooth shape. The Smooth parameter is a bit of a mystery to me.
RemoveKnot used on two interior knot lines takes it back to the original shape. This pair of surfaces has an exactly equivalent single surface.
