Jon,
Have you seen Chris Hall's blog here: [url=http://thecarpentryway.blogspot.com/][/url] http://thecarpentryway.blogspot.com/
His books are excellent, and the similarities to French and German layout evident, in my opinion. Again, the drawing methods are similar but the joinery and architecture are different.

I suggest that Asian carpentry shows as much curved and crooked timber work as French, if not more.
