Custom angular or circular Hatch pattern
@marko_ribar, your pattern definitions can go from 0- through 179-degree directions, and stop there -- the 0-degree direction covers the 180-degree direction, too, and 1 covers 181, etc.
@fkp7057, your right image can be as simple as this:
*RADIAL15, Radial lines at 15-degree increments
0, 0,0, 0,1
15, 0,0, 0,1
30, 0,0, 0,1
45, 0,0, 0,1
60, 0,0, 0,1
75, 0,0, 0,1
90, 0,0, 0,1
105, 0,0, 0,1
120, 0,0, 0,1
135, 0,0, 0,1
150, 0,0, 0,1
165, 0,0, 0,1
Set the pattern origin to the center of your Circle [in the image, or otherwise wherever you want the radiating to radiate from] and set the Scale factor to whatever it takes to get the "other stuff" [the parallel repeats of the defined linesets] outside the Hatched area.
Your left image can't be done with a Hatch pattern if you're intending it to have actual curvature -- Hatch patterns can only be made of straight-line segments [or dots, which are zero-length straight-line segments, as in some of marko's suggestions]. But it could be done with an AutoLisp routine easily enough, if that's of interest.
Actually, neither hatch can really be done well with the hatch features. The hatch pattern coded in the last post will only work to fill a square and that only if the hatch pattern scale equals the size of the square. Might as well create both with a block, insert, scale, and clip, which is what I do. LISP can work as well but is probably overkill.
Look into superhatch if you want to experiment with quirky hatches that the hatch command can't handle. It can work with circles, blocks, images, etc.
Just for fun, here is what occurs if the radial hatch coded is put at a scale of 1 inside a 24"x24" square with the basepoint in the center of the square.

NOT TRUE! I don't know where that notion is coming from.... It will fill any shape at all, and the scale factor can be anything at all that's large enough to drive the extras outboard of the Hatched area, or larger to any degree you like. The desired portion around the origin will look exactly the same whether the scale factor is just barely big enough to do that, or set to a million, or a googol.
