Custom Hatches Look Bizarre in AutoCAD 2023?

[betsy.kirtland]

Hi all,

I have a custom hatch that I use that looks great in AutoCAD C3D 2021 - see screenshot to see what it should look like. When I use the same hatch in AutoCAD C3D 2023, none of the lines connect and it looks incredibly jumbled. Can anyone provide any insight into why this might be happening, and how I can fix it?

In both screenshots, the scale of the hatch is set to 1 and the rotation is set to 0. Both are drawn in WCS, and REGEN/REA does nothing. The lines appeared jumbled during the plot also, so I don't believe it to be a graphics issue.

In C3D 2023, set GFXDX12 to 0 (that's a zero) then restart the program: does that fix the display issue?

[Kent1Cooper · Accepted solution]

That looks like a case of being very far from the origin.  Use the Hatch editing part of the ribbon to set an origin within the area of the Hatch object, and see whether that fixes it.

[betsy.kirtland]

Unfortunately, changing that variable did not change anything.

[betsy.kirtland]

I was optimistic about this, but adjusting the location of the origin also did not fix the issue.

Good to know: try @Kent1Cooper tip about your area being too far away from 0,0,0 and moving it closer as a fix.

[betsy.kirtland]

I tried resetting the origin to be within the hatch using the Hatch editing part of the ribbon and also moving the actual hatch object closer to 0,0 and both had no effect.

Share your sample .dwg, so nobody have to guess

I'm glad you asked for this, because it forced me to realize that I was using an outdated hatch pattern that I didn't have saved in my support folder anymore. Once I changed it to the correct hatch, updating the origin like @Kent1Cooper suggested worked like a charm.

Thank you all for the help!!

[EDIT:  hadn't seen Message 11 yet, but anyway...]

It does not appear to be a problem in the pattern definition itself, which is giving me this:

But if that's near 0,0, and I Set its Origin far away [e.g. 10000,10000], I get this:

so I think that must be the issue.  Does setting its origin within it and REGEN fix it?  [The REGEN is not required to change it for me, but maybe in some circumstance....]

The effect could be lessened [but not eliminated] by increasing the precision in the pattern definition, but:

A)  you'd need to do some real work to figure out the additional decimal places to add in most cases; and

B)  you'd run up against the 80-character code-line length limit pretty quickly.
