thread561-162627 Studio spline tangent to a surface?

Trying to place a studio spline from a point to an edge of a surface so that it would stay tangent to the surface, when surface shape updates. Doesn't work. A fixed constraint is created that does not update.

Hi,

Can you create an associative curve on the surface first (e.g. intersection with a datum), so that the spline can stay tangent to that.
