Hey, so im trying to create this sketch on the surface, but the lines keep coming up red, and i cant get the vertical line to coincide with the bottom edge. any help would be much appreciated.
cheers

Luke,
I can't give you an answer on why, I get the same result but a couple of suggestions.
One is to create a plane and add a relation of On Plane
The other is to use the Offset on Surface sketch tool
thanks michael,
once ive got those 2 lines, how could i go about blending them? I'm trying to make a fillet between the two but struggling
cheers,
luke
Hi Luke
Might be the last option you try, if no simpler solutions present, but a fall back could be to SplitLine the Face, Copy the surface/Thicken and use the Fillet Feature
I believe the answer is obvious: very sophisticated math must be involved to handle this case.
The work around to simplify the model as Thomas Voetmann suggested looks to me as the best solution.
I have similar experience with Spline on Surface. But I found I almost never need them.
Instead I create (or find) a plane close to tangent to the surface. I make my sketch with splines, fillets etc. and use either Split-Line or Project Curve.
Remember "fillets" on a curved surface are not an entity with constant radius anyway, and the splines are more easy to manipulate in the 2D-sketch environment. One disadvantage is that you dont get immediate response when you make changes.
