Pattycake

Hey Vectorworks community, I'm working on a web-based platform to help assist in the making of Pattern files (.PAT files). I'm trying to find a page on Vectorworks that lists out specific .PAT file rules for Vectorworks, but I'm having trouble locating this. (AutoCAD for example has character limits, naming rules, etc - or the PAT file wont work - I attached an example image). Can someone link me to where this help file is located? Many thanks! - Kyle
