I can’t see the second image, but as a guess you’re stuggling to create the line?  If you create an isosurface of constant x, y or z  AND select the outer mesh face when you press Create you’ll get a surface (possibly 2 in this case as it’s a annular channel) of the intersect of the isosurface and mesh surface. You may not be able to plot length, but will be able to plot position for that approach.
