 Help with a hatch pattern
20-07-2012 01:57 . pm | View his/her posts only
Hello all:
I'm trying to create a hatch patternto match a floor tile. I'm almost there but the last part is frustratingme.
I want a 24" long x6" wide plank tile. The tiles should be offset from each other8" (a 2/3 1/3 pattern lengthwise). My problem is I only can get a6" offset (3/4 1/4 pattern).
Here's the code I've got:
0, 0,0, 0,6
90, 0,0, 6,6, 6,-18
I've adjusted every number butcan't get what I need. Any help would be GREATLY appreciated!!!

You may be confused by the admittedly confusing fact that the x origin,y origin entries are in relation to 0-degree orientation [although that doesn't matter in this case, with them being 0,0], but the delta-x,delta-y and the dash-1,dash-2,etc. entries are in relation to the angle of the current line set [in this case the 90-degree direction]. Given the 0-degree direction of the unbroken lines, I believe with the 90-degree lines you want a delta-x of 6 for the plank width, and a delta-y of 8 for the offset in the direction of the plank length, and a dash-2 of -12 for the two planks that are at a different offset position in between each plank that's aligned with the current line set. Try this [I haven't tested it]:
0, 0,0, 0,6
90, 0,0, 6,8, 6,-12
Make that 8 a -8 instead, if you want them offset in the other direction.
