You are pretty close 😎 There are 3 main different ways to make this type of pattern:
- One definition for the horizontal line, and one for the consistently shifting vertical line
- One line for horizontals, with a vertical line for each unique instance in the base module (3 in this case)
- One line for every line within the base 'module' of the repeatable pattern
You are attempting to write it using approach #2. Note that for PAT files, it does not matter file performance wise (size/speed) whether you do approach 1, 2 or 3. We've done extensive research into this, and there is no noticeable affect on file performance, size, or degradation in any other way when (as in your file) there are 2 lines vs 4 vs 6. Not even noticeable in 2 vs 40 vs 600.
For your #2 approach, try this PAT and see if it works: 4x16 with 1/3 Offset
0, 0, 4, 0, 4
90, 0, 0, 0, 16, 4, -8
90, 5.3333333, 4, 0, 16, 4, -8
90, 10.6666666, 8, 0, 16, 4, -8
