Got it. Thank you. It was buried pretty deep for something I thought was basic. But I found it.
Generally speaking crop marks and die lines would not be synonymous. Die cuts are usually secial shapes cut with a cutting die in one "chomp" where crops are used to tell a guillotine cutter operator where to trim each side of a rectangle. Die lines are usually created using a designnated spot color and set to overplint so they can be output separately and used to control the machine that creates the cutter.
100% agree with Peter.
the cropmarks script that ships with InDesign is OK, there is a better one that removes overlapping cropmarks and allows bleeds to be calculated into the equation: http://www.scriptopedia.org/en/lien-phoca/file/59-advancedcropmarks.html
