Custom Hatch pattern for ceiling plz help

[Alaaeldin.Alsahli]

Hi All

I have a Ceiling Pattern a bit custom, it goes with 476 spacing then 610 then 305 then 610 then 476. I am trying to figure a way but still newbie with hatch coding. so this how it look like. is there away to code this. 

I tried this but didn't work. as you see it is for revit but it takes autocad .pat.

;;; revit metric.pat file v. 3.0 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; (c) 2000-2003 Autodesk Revit ;;;
;
; Please see the revit.pat file distributed with Revit for an explanation of this file's format.

*0 Ceiling custom, 600 x 1200 Tiles
;%TYPE=MODEL
0, 0, 0, 0, 1200
90, 0, 0, 0, 610
90, 0, 0, 0, 915
90, 0, 0, 0, 1525
90, 0, 0, 0, 2001

Try this [lightly tested]:

*WHATEVER, 1200 x 476/610/305/610 Tiles
0, 0, 0, 0, 1200
90, 0, 0, 0, 2001
90, 476, 0, 0, 2001
90, 1086, 0, 0, 2001
90, 1391, 0, 0, 2001

You need the spacing from each vertical line to the next occurrence of the same line in the cycle  to be the sum of the sequence of widths in one cycle, which is the 2001.  Each set of such lines starts at a different place, not all at 0,0.
