I've been fighting with a part I'm making for quite a while. I've created a swept loft, on which I'm trying to create a surface spline which follows along the surface but is constrained by points which are moving closer to the edge and also follows the curvature of another spline:
When I use the spline on surface tool, it doesn't create a spline, I'm unsure why, but it creates 2 separate 3d lines/ arcs on the surface, however, they are not a spline. I need the it splined as it requires to be one tangent part rather than lines just coincident on the surface.
I need it to follow the trajectory of the other spline, used to guide the curvature of the part, whilst also moving towards the outer edge - the reason for the 3 points it coincides with are so I can alter it's path, then I will look to offset and extrude from the surface.
I have also attached the file, SW2016, if it helps.
Thank you in advance, Chris
