Hi anthony, just g1 gives you tangent continuity, g2 is continuity of curvature and g3 is continuity of the rate of change of curvature.

But if it is tangency that you are shooting for, then no you don't need g2 or g3 type options in order to attain that - g1 is the one for tangent continuity.

It's really hard for me to visualize what you are describing - I would really need at least a screenshot and more ideally a 3DM model to have much of a chance at figuring out what you are trying to do.
