Enumeration for Document Lineweights?

I'm trying to correct an issue where the line weights in ourdrawings are wrong. I can't find the enumeration in the API to setthe line weights. I've found the system option, but in 2009 theyswitched from being driven bySystem Options to being driven byDocument Options. And, I can't find the enumeration forthat.

Anyone know what it is?

Thanks,
