If I'm understanding you correctly, you're getting close. You only need two lines described, one which is four inches above the other, and each will repeat twelve inches apart (4" spacing + 8" spacing = 12" total separation from one line to its repeat). Try this code here:
*4-8 repeat,
;%TYPE=MODEL
0, 0, 0, 0, 12
0, 0, 4, 0, 12
That will produce this pattern:
@Redrunner92 has you covered.
Case you are curious, if you are frequently writing your own PAT files, we also provide a free real-time drawing platform for PAT files. That way when you change a value, you can see the results immediately. And you no longer need to constantly re-save/re-load/repeat to try and test out a pattern. Cheers :birthday_cake:
