Hello,

I find it difficult to compare hatch pattern JSON data with actual AutoCAD hatch pattern values, is there something I need to know to properly interpret these values? In particular, the `origin` and `offset` doesn't sum up...

I've also checked [this article](https://knowledge.autodesk.com/support/autocad-lt/learn-explore/caas/CloudHelp/cloudhelp/2015/ENU/AutoCAD-LT/files/GUID-A6F2E6FF-1717-44B6-A476-0CA817ADD77E-htm.html) without succeding. 

Thank you.
