You have a small gap between the splines. If this is as intended, use the pulldown on the Point dialog and change the Type from Inferred Point to Intersection Point then select the splines one at a time. Make sure that whichever spline you want the point to lie on is the first object selected when using this method.
If you wish to close the gap, then project Composite Curve (3) and then Snap Point will work. The curve lying on the surface's trim edge is not necessary to get an intersection with Composite Curve (3).
I see no reason why the intersection fails to be identified. There is a small gap and I tried adjusting tolerances with no success. If I use Project Curve to project Composite Curve(3) to the surface the intersection is found. Similarly if I create an Intersection Curve (using the original curve to create a datum plane) the intersection is found. I created additional curves on the surface, with larger gaps than Composite Curve(3), and the intersection was found.
You might want to open a case with GTAC to have development review your part and explain why it's not possible. I did find an old PR which suggested creating an Intersection Point as an intermediate step in the case where the snap intersection was not working.
Hi all, I'm still a little confused by the issue.
In "Point" > "Intersection Point" there seems to be
Q1: If the gap makes snap "Intersection" fail, why doesn't the gap stop "Point" > "Intersection Point" from working?
Q2: What does it means when "Point" > "Intersection Point" gives an intersection point associatively (successfully)?
Success ("Point" > "Intersection Point")
Failure ("Point" > "Intersection Point")
