Cross Sectioning

ok, I am trying to load an object (.x preferably), intersect it with a plane at any height to get a cross-section, and be able to turn that cross section into a 2d image, all in b3d. i havent had much luck trying on my own, nor have i found anything in the code archives. so i was wondering if any of you had any ideas on how i could go about doing this.

JS

There is (or at least used to be) an excellent crosssection routine in the code archives.
