Extend Splines Curves To Intersect

I am looking for any recommendations on how I can extend the airfoil spline curves shown in the image below so that they intersect. I tried to copy the geometry to a sketch but the sketch extend tool does not appear to work. Also, the sketch trim corner command looks like it wants to work but doesn't. Any ideas? I realize I could just add new segments to the end for the intersection but I would prefer to extend the existing spline curves if possible.

Hi there @David_McMahon,

 

I think it is made more difficult when the curves are "Table Curve" segments. Do you need to complete these in the sketch?.....as you could always extend & trim the resulting extruded, or lofted surfaces. Assuming that a 3D model is the eventual goal here.

@David_McMahon,

 

I also made a new sketch, and used the "Project to Sketch" command, to capture your two Table Curves, but then deleted the link relationship, so that I could then modify them, using "Trim Corner" to extend the tip closed.....could then "Extrude" with the "Select From Sketch" input option.

Sean,

 

Awesome, that works! It did not occur to me to delete the link relationships. That was the part I was missing.

Yeah, a less robust method, but a way forward all the same.......if there was a fear of accidentally nudging the profile out of place, you could also add either of the "Rigid Set" or the "Lock" relationships to the finished sketch.
