If it's urgent, make a block and use the superhatch command from Express tools to place it.

That should not be difficult. But a clarification: Hatch patterns repeat continuously, so it would be necessary to know whether the image represents one complete "cycle" of the pattern, and a larger area would be filled with what's in the image, "tiled" repeatedly, resulting in two rows and eight columns of smaller squares between all areas of larger squares. Or might it be different, for example with areas of larger squares occurring again immediately adjacent to the edges of what's in the image [one row and four columns of smaller squares between them]?

OR: Can you draw the outline of the inside half-density area and just Hatch both areas with User-defined double-direction patterns at two different spacings?

Thanks a lot for your assistance. the attached image shows a complete cycle and the same has to be repeated.
This is a flooring tile pattern and the area to be hatched is pretty huge.
Please help

I think this does what you're after, in minimal testing:

*Tile2sizes, Tile pattern: field of larger tiles within smaller tiles
0, 0,0, 0,1200
0, 0,100, 0,200
0, -400,0, 0,200, 800,-2000
90, 0,0, 0,200
90, 100,0, 0,2800
90, 300,0, 0,2800
90, -100,0, 0,2800
90, -300,0, 0,2800
90, 100,-100, 0,200, 200,-1000

For simplicity, it actually draws some partial-length segments overtop of continuous-length segments [if you Explode a Hatch pattern made with it, you'll find some overlapping Lines in the result]. It could be made to not do that, but it would be considerably longer.

Change the pattern name as desired.
