Hi Alec, Thanks for that link, I will try to figure out what my issue is using that function.
However, in both examples they use "allIntersections". My old code just used a function "intersect" from here: http://download.autodesk.com/us/maya/2009help/api/class_m_fn_mesh.html#4f5a5cc3ab4834b8045239a3438930dc If the link you gave has API1 and API2 with the same allIntersections method, do you know what is different than the intersect method I had been using.
