Continuity defines the junction point between two curves or surfaces. A higher continuity implies a less visible junction point. G0, G1, and G2 continuity is independent of the parameterization of the curve or surface. C0, C1, and C2 continuity is dependent on the parameterization of the curve or surface. In general, C continuity is more stringent than G continuity. For example, C2 continuity always implies G2 continuity, and C1 continuity always implies G1 continuity, but not vice versa.
Curves or surfaces that meet are said to have continuity of G0, or contact continuity. Curves or surfaces that are tangent have a continuity of G1, or tangent continuity. Curves or surfaces for which the rate of change of the radius of curvature is the same where they meet have a continuity of G2, also described as curvature continuous. You can use curvature continuous in creating face blend fillets. A loft with side tangency is an example of level G1.
If the junction point of two curves or surfaces is G2 curvature continuous, continuity may not be C2 or even C1 because the curves or surfaces may be parameterized such that at equal change of parameter near the junction, the parameterized point on one curve or surface may move more than the parameterized point on the other curve or surface. However, if the curves or surfaces that meet are parameterized such that the amount of movement for each point is the same, then the junction continuity is both C1 and C2 as well as G1 and G2.

degrees of freedom
Geometry that is not defined by dimensions or relations is free to move. In 2D
sketches, there are three degrees of freedom: movement along the X and Y axes, and rotation
about the Z axis (the axis normal to the sketch plane). In 3D sketches and in assemblies,
there are six degrees of freedom: movement along the X, Y, and Z axes, and rotation about the
X, Y, and Z axes. See under defined
