Here’s a variation on MoI’s Box command that produces standard dimensional lumber. Not much more needs to be said other than that the intent was to reduce errors that might arise by typing incorrect values for dimensions.

The “database” in Lumber.htm is easy to edit to add other sizes, just make sure to follow the option value formatting, providing dimensions in both inches and millimeters. The script will choose which to use based upon the current model units. I did it this way as I believe that the dimensions are slightly different in non-US markets.
