Custom Hatch Pattern

[jagostinho]

Hello,

I need to create a custom hatch pattern such as the one attached. I know nothing on PAT files syntax but decided to give it a go.
I used these settings but it is not resulting the way I want but cannot find what to change.
(I have rounded the values to make it easier as these are irrelevant)

;; ;; Random Stone Paving ;;
*RANDOMSTONE, Random Stone Paving
;%TYPE=MODEL
0, 0,0, 0,160
0, 0,130, 0,160
0, 0,100, 0,160
0, 0,100, 0,160
90, 120,160, 0,130
90, 290,290, 0,100
90, 330,390, 0,100
90, 250,490, 0,130
90, 290,620, 0,100


Can some PAT experienced users out there give me a hand, please?

Many thanks.

You'll find patterns containing vertical and horizontal elements in a rectangular arrangement are straightforward if you work at it.
Your swatch covers a rectangle 1500 wide by 720 tall and inspecting the above should show how they recur in the pattern definition.
The unbroken horizontal lines recur spaced 720 apart while the broken verticals all recur at 1500 horizontally and 720 vertically.
The last two numbers on all of the vertical definitions when summed unsigned also add to 720.
