Custom Hatch Pattern Troubleshooting

After spending waaaay too much time looking for a board and batten hatch pattern for vanilla ACAD, I found this in a Revit forum:

*Board & Batten, 2.5" Batten at 16" o.c.

;%TYPE=MODEL

90, 0, 0, 16, 16, 16

90, 2.5, 0, 16, 16, 16

Doesn't work for vanilla ACAD, though. Since I don't know the first thing about LISP programming (somehow it is never as 'easy' as the people who say, "Oh, it's easy!" claim), would anyone be kind enough to help me figure out what needs to change to be a regular ol' AutoCAD .pat?

Have a look at acad.pat or acadiso.pat in particular say brick pattern or this

*BRICK, Brick or masonry-type surface

0, 0,0, 0,.25

90, 0,0, 0,.5, .25,-.25

90, .25,0, 0,.5, -.25,.25

*AR-B88, 8x8 Block elevation stretcher bond

0, 0,0, 0,8

90, 0,0, 8,4,

*Board & Batten, 2.5" Batten at 16" o.c.

;%TYPE=MODEL

90, 0, 0, 16, 16, 16

90, 2.5, 0, 16, 16, 16

 

Main problem is there's 6 numbers in each element definition when unbroken lines need only 5 viz:

angle, x-origin, y-origin, shift, spacing where shift can be zero for unbroken lines.

Pattern name must match pattern filename so simplify the name and store this in BOARDBATTEN.PAT somewhere on your support file search path:

*BoardBatten, Battens at 16 in centres.

90, 0, 0, 0, 16

90, 2.5, 0, 0, 16

should show pairs of vertical lines 2.5 units apart repeated at 16 units. If you are working in inches that should be what you want otherwise scale accordingly.
