I have been trying to do some surfacing in SWx 2008 SP5.0. I
was in the process of fine tuning the surface by editing the
splines used to create it when I noticed the surface was not
respending to the changes. Turns out the spline wasn't acting
properly. I have an intersection curve and a spline which are
constrained to be tangent. When I created the constraint, the
spline did as it should in moved into tangency. If I try to change
the spline by lengthening or shortening the intersect curve the
tangent constraint does not remain in force. It's still there on
the list, it just isn't active (or something??) If I delete the
tangent constraint and re-create it, it works -- once. Why would a
constraint only work when you first create it? Or is there some
other way to apply a tangent constraint to a spline?
These are images illustrating the problem. First is the original geometry, then after editing the intersection curve, finally after deleting and re-creating the tangent constraint;

Bill, You are absolutely right. The current state of splines is not robust in rebuild. Please post your ideas and support the current ideas related to better splines in the Idea's Section.
