How do you divide a model into very uncommon lengths, like thirteens?
(Besides Reference Finder, or making 14ths and cutting).

Well, there are several geometric constructions for divisions like that. Mainly for more common divisions such as 3rds, 5ths, and 9ths, but there are ways to get more uncommon divisions too. I learned a lot from this
paper on Robert Lang's site.

This means that if you want to divide in (for example) 5ths (n+1), you first need to divide in 4ths (n). This works for every number. If you want I can PM you with proof (if you don't believe me):P.

Yup, that's basically what the haga theorem is all about
