Hatch displays crossed lines insted of pattern

Anonymous — Fri, 06 Nov 2020 18:25:55 GMT

Hello; today`s issue: 😉
Sinced I turn on aCad 2018 today when i try to insert a hatch in shape aCad shows crossed or chaotic lines insted of exact shape.

This happen both to aCad default hatches and my own too. It works for over a year and broke suddenly :?

I tried setting new hatch start point but didn`t work..

In the picture we`re suppose to see three SAND hatches with different scale...

Is the hatch boundary far, far away from 0,0 ?

If it's not a too-far-from-the-origin issue....

AutoCAD's sand patterns [in different versions and/or overlays called AR-SAND and Sitework_Sand] use lineset angles of 7.5, 37.5, -32.5 and -42.5 degrees. The parts of the patterns in your image look like they could be at those angles. If the patterns are at 0° rotation, and you Explode them and check the directions of the resulting lines, are those the angles? If so, that would suggest that your definition is there but has been corrupted, and the pen-down-pen-up sequences at the ends of the pattern definition lines have been lost somehow, or commented out, or something. Check the definition in whatever pattern file you use, and see whether lines in it end with sequences similar to 0,-1.52,0,-1.7,0,-1.625 [zero-length pen-down entries followed by pen-up entries of varying lengths].

Files are not corupted. FY this is my hatch file:
"*XX
0, 0,4, 0,32, 10,-32
90, 10,0, 0,-42, 10,-22"

And it should look like this: (Pic.1)

But i look like this: (Pic.2)

And funny fact; when i select this hatch and press "ctrl+X" i shows me my pattern!!(Pic.1), until i left-click it in new position, then its again like Pic.2... So the hatch works, but it`s somehow not shown properly...

So now, the answer to the question in Message 2 is....

[Being extremely far from the origin can cause assorted problems, though I don't know whether this kind of thing is one of them.]

Ctrl+X is "cut"

then you Left click?

I don't get that step at all

@Anonymous Sry,

1. first Ctrl-X

2. then Crl-V (after pressing crtl V, the cutted object is shown transparently, until i "left click" it in new position. And when its transparent it shows me the right pattern. Then when i insert it in new place its again like crossed or chaotic lines.

@Kent1Cooper i tried setting new origin near hatches and i did not make any difference...

Can you upload your .dwg ?

We weren't talking about the origin of the Hatch pattern, but of the drawing. If you're drawing at an enormous distance away from the drawing origin 0,0,0, you can expect problems, because AutoCAD has a limit to the number of significant figures in numerical values. See >this< for an extreme case. How they got to be that far away, I can't imagine, but it did cause trouble.

What are the coordinates of some location on one of your Hatch boundaries?

@Kent1Cooper but it`s my template drawing which i was using for few years, and once i turn on cad today, every drawing i try to make, even new one, has such problems with hatches.

Looks like your new Autocad doesn't have that hatch pattern in its search path,

The pattern only in your drawing so you can't hatch it again.

Then if it's not way far away from the origin, and it's not a pattern-definition issue, I don't have any better ideas, other than that you might need to repair/re-install AutoCAD.
