Hmmm. These are really lines or planes. You can certainly produce one of them using the features in the D/C: Surface Miscellaneous page. And you can generate uniformly spaced tick marks using the same, but that's not what you want. You want lines corresponding to your slices. I can think of two very inelegant solutions: * Generate volumetric planes at the slices you specify (i.e., zeroes everywhere except the slices corresponding to your slices), and then generate a surface from that segmentation. (Connect them along the y axis, if needed, to make them all be one surface.) Load this as a VTK over your surface. I'm trying not to imagine how ugly this might look. * Generate separate captures for each slice level, modifying the cartesian axis offset at each one, and then frankenstein them together somehow. > given that the data is all in caret is there some way to use caret to do this? > > maybe foci? I've actually never used foci. perhaps that's what I want. You want lines/planes -- not points, though you could use foci to generate markers along a constant z plane, and then photoshop more visible lines at your too-hard-to-see foci marks. > > not really sure how to make one or make it do that for me. > > it's a big help if I can at least semi-automate the section/surface > relationship.
