Hi

I'm looking for help on how to join lines connected to the larger airfoil (on a plane in the x-axis) to the smaller airfoil (on a plane in the z-axis and is also raised up in the y-axis). 

I've tried to 'Add relationships', selected the point and the sketch and 'Pierce' but it says they can't intercept.

I need this as a continuous line so that when I 'Loft' my design I can use these 'Spline' lines as guide curves.

Any help would be much appreciated.
