Create sketch lines from geometry

[Intuos5]

I was wondering, is there a way to derive sketch lines from geometry? For instance, if I were to create a t-spline object, can I derive a 3D spline from one of the edge loops, thereby following the surface? The tool I am looking for is something similar to 'Create shape' in 3ds Max.

On the sketch menu under project there's an option Include 3d Geometry, think that's what you're after.

As far as I tried, it only projects the border edges onto a horizontal plane. So I may be doing something wrong here. 
In this example I used a manipulated t-spline plane, intersected by an offset reference plane. Although I would actually prefer to select the edge and derive a spline from it, as if the 3D loop selection were the spline, so to say.

Don't think you used Include 3d Geometry. And please don't attach pictures. There's an option Photos on the editor toolbar to embed them, please use this option.

I think I get it now, the 'intersect' option can be used in the middle of geometry to project it on a plane, whereas include 3D geometry only projects the borders of the plane (so not on edges in the middle of the plane). Since the borders were flat, I did not notice that it works this way. Though this does mean that it's only possible to get the spline from projections, rather than as splines that I can manipulate freely? If so I will add a new idea on Ideastation.
