looking for a pat file

can someone look at this tile link layout and provide a hatch pattern for this? it is like a ribbon layout.

thanks for any and all help!!

I can sort of imagine it might be possible to make such a pattern definition that would look something like this:

But will it be acceptable to you that [as with all Hatch patterns] the "curves" will have to be made up of straight segments, something like this?

Those segments are part of what would be a regular 24-sided polygon if it went all the way around. It could be a little closer to looking "curved" with a greater number than 24, but it can't have actual curvature in it.

But you could have true curvature if SUPERHATCH will do what you need -- look into that.

No -- I drew that to illustrate, but it's not a Hatch pattern definition [yet]. I can't spend time working that out right now, but maybe @hugha will jump in with a HatchKit solution.

Thanks very much, Kent, for the lead but as you infer there can be quite some work in vectorising pixels and that represents the bulk of this ask.

By contrast, the sunburst brick https://forums.autodesk.com/t5/autocad-forum/4x16-hatch/m-p/10904898 required just a few minutes to analyse, set up and export as DXF and a few more to run through HatchKit and post.

unfortunately i dont know how to do it, that is why i am asking for help. others provided the pat file for me on that one, but this one i dont know how to draw.

thanks

Neither did I, but I eye-balled something in a quickie approximation (which I didn't keep). It sort of looks like along the line where the wavy curves touch tangentially, they form almost parts of a circle but not exactly -- kind of elliptical, though I based mine on a circular idea because the regular 24-gon is much easier to work with -- and in the other direction the curvature is of greater radius and a little farther apart than forming parts of a circle. I could try again to make something that could form the basis of a Hatchkit conversion, but do you have any actual size/spacing/repeat-cycle numbers? There are numbers on their website, but what is the 22", and the 9-1/4", and the 3/8"? How wide should the bands be at narrowest and widest, relative to whatever is decided as a nominal radius for some part of it? My image has band edges crossing each other in some places and trimmed away in others -- which would you want? Etc., etc.

@suzieSEJ5A if you cannot find something similar on the web that "will do" https://www.google.com/search?q=aurtocad+hatch+patterns+downloads
then you may have to pay someone for their time to create it for you: start here https://servicesmarketplace.autodesk.com/

It's not hard, just a bit tedious.

Load the source image of the tiles fullsize as a background to be manually or somehow (Scan2Cad?) automagically traced in CAD to produce a bunch of straight vectors covering the minimum necessary representative sample much as Kent's previous hard work has already illustrated.

Save as DXF.

Converting DXF to a PAT file is then as straightforward as was shown in response to your earlier request for a different pattern.

That actually works pretty well:

See the larger area of it using the "unit" Block in the attached drawing.
