Brad,
The Sketchup plugin ruby script already uses some of the Hawkindale angles, so it wouldn't take that much more to draw out the 3D representation of all the Hawkindale angles. I'll add it to my to do list.
I thinking about adding something like this as well.
http://stereotomy-blog.blogspot.com/2011_09_01_archive.htmlI have the book "Traité Théorique et Pratique de Charpente"
but never got around to drawing out any of the images in the book. But with Tim Moore translating the text from French to English I might give it a try.
