I've been searching for a way to get cutlist quantities, seems like there isn't an easy way to do it.  Then I ran accross this example macro on api help.

Somehow this macro can count cutlist quantities.  Its really complicated and I'm still trying to understand.

After I come to understand how it works, and strip out all the gak, I hope I can use it to help sync weldments with our ERP.
