Aaron, would you be willing to post an example? Say a Mallerated version of modular running bond? I think I understand what you are saying conceptually (coursing from a "base" dimension rather than from the previous course), but I am not sure about how to actually execute that in PAT language. Of course my understand of PAT language is mostly change a value, reload, see what happens, change again, repeat a bazillion times until something finally works. I am getting ready to revise a bunch of patterns and would like to understand everything better going in. Likely to be more expert at PATs than I really want by the time I am done.
Thanks,
Gordon
