Hatch patern code

[djurk_haas]

Hello,

To make my own hatch pattern (code in *.pat file), I am analyzing an existing code of a pattern (see code below).
Can someone tell me how to get the values ​​of the Offset-x, offset-y and Gap.
In the appendix a drawing in which I have retrieved the values ​​(red line = gap and magenta lines are the offset x / y) but now I get stuck. How can I reproduce these values ​​without a drawing?

*xxxx-Test,3 POINT STAR
210.0686, 0.500,0.420, 13.892369,0.045549, 0.439090,-21.515408
329.9314, 0.500,0.420, 8.062129,0.045549, 0.439090,-21.515408
270.0000, 0.500,0.860, 1.000,1.000, 0.440000,-0.560

I thought I would post a picture of what I got working out the definition manually, just to prove that it can be done by hand!
