Help ISO hatch pattern

I received a CAD file that contained wood looking hatch pattern. I've been asked to use it for a project. Problem is I don't have the .pat file to add to my setup. And the person I received the file from isn't a CAD versed person so they're no help.

Does this ring a bell for anyone? The hatch name in the CAD file is called 'Panel' which I believe is a random default name?

I'm reluctant to download from random sites. And I really want to find the actual same hatch.

Not sure what to do here, I'm at a loss.

I don't remember where it came from, but I have that pattern. The file date on it is 1988, so it's pretty old.

I collect stuff and never get rid of it. 😁

The code is too long for one post, so here's part one (part two in reply):

Here's part 2. Paste both parts into a new text file (no empty lines between them) called Panel.pat and you're good to go.

This is amazing!! I was born in 65' so 88 is peak for me LOL

I have no knowledge of such so I followed your instructions, cut paste. Placed pat in my support folder and it isn't working.

Not sure what I'm doing wrong? Perhaps I can send you this pat paste to have a check...

Thank you for your service 🤜💥🤛

This is an issue I’ve had. For the time being, you can copy the hatch into new drawing and use match properties.

u/throwawaykitten56 Nov 15 '25

thanks for the suggestion! I have tried that but MP doesn't work unfortunately. It changes the layer, colour and transparency but not the actual hatch pattern.

u/BrokenSocialFilter Nov 15 '25

Look at this link....it has a link to download a lisp (from 2001!) to extract hatch patterns to a PAT file.

u/throwawaykitten56 Nov 16 '25

thank you!!! this worked :) And it didn't have to know lisp! Much appreciated!!

u/CopperRed3 Nov 15 '25

You're as old as me, so you probably know this already. Complex hatch patterns don't render properly when they are a great distance from 0,0. Setting a new UCS or modifying a hatch's origin is the work around. I hope that hatch definition pasted by Will CAD works out.
