Maybe you could put a dummy header, dummy king post, purlin, hip or valley, plumb and square purlin, and jack in to really see it.

I've seen Tim's blog. I took a course with the Guild at a conference in drawing the Mazzerole sawhorse with all of the twisted braces. It was very cool.

Are you going to western conference coming up in Monterey? I'll be out there, and it would be good to meet you in person.
