Autodesk Inventor

Can someone from Autodesk point me to a list, or post one on the Wiki detailing which materials these Physical assets relate to. I can see they are categorized as wood etc but the designations are meaningless to me. I would like to use them if they are relevant.

can someone from Autodesk please comment on this?

Thanks to a few awesome people on Twitter, it turns out these designations are Timber Strength Grades. Here are some links to help people out if they want to know:
