With an unstructured tetrahedral field, MapToPlane outputs the exact planar intersection as an unstructured triangular field. Is there some way to do the analogous thing for a line; i.e. MapToLine? MapToPlane requires a 3D field as input, so a recursive use won't work. I can certainly construct a linear 1D grid and use Map, but this really isn't what I want, as I'm looking for the exact intersection.
