I made a custom brick hatch for a project that, based on my basic understanding of how .PAT files work, should create a header course every 7 courses. However, when I load it into Revit (I'm using 2019), I get nothing but a grid. Where have I gone astray? I uploaded my file to pattycake.io, which displays it as I intended, and returns no errors, so I'm really at a loss for how to make it work. The text of the .PAT file is below.

This is something @Pattycake_Kyle may help
I simplified the .PAT file, but to no avail. Loading it into Revit gives the same result.

Hey @winYHZZH Sorry about the late reply here. This is a bug in our system, we are pushing out an update soon to fix.
Since PAT files should always have a negative value for space, we draw it as if it is there, which is a bug on our part. This was also found by @jason4W7GR in this thread here; https://forums.autodesk.com/t5/revit-architecture-forum/custom-hatch-pattern-not-rendering-corectly/...
You are correct, just add a negative value to the space and that fixes your issue.
Easiest way to remember this is that the space values should be negative values (to represent 'pen up'), while the dash values should be positive (to represent 'pen down'). And always free free to ping me directly here or reach out via our contact page!
Case anyone comes across this thread. This has been fixed in Pattycake Version 2.
We decided to still draw the pattern as the user 'intends' the pattern to be. But we now highlight this problem using our error notification system :ausrufezeichen: Hover over the icon and it gives you detail on what is wrong.
Thanks to everyone who helped us find this bug! :käfer: We appreciate it. ![]()
