I wrote a book. I mean, after all, I created the writing system Parametric Writing, so I had to use it on something. You can get the fulltext in printing format from my blog post over on my personal website: Post with PDF of Understructure
Of course, that is a flat, raw text document. It is about 250 pages in trade size.
What you really want to look at is the Parametric Writing editor view of my book. You’ll see the Briefs and Rules that I defined, and how they link into and throughout the book. Click here to open the editor: PW Understructure Story
