Custom Hatch Pattern - LVT

trEQ4GG — Tue, 21 May 2024 17:26:57 GMT

Hello!

I am trying to create a custom hatch pattern for a 6.25" x 42" LVT plank with a 33% offset. For whatever reason, I have had extreme difficulty creating custom hatches and getting ahold of autodesk to trouble shoot over the phone has been difficult. I am not sure why it doesn't work out for me. I have attached a screen shot of the protocols we follow at work that USED to work for me. Below is what I have put into the .pat file, yet its not there when I open cad up again...

*LVT 6.25x42 33% Offset, LVT Pattern
0, 0,0, 14,6.25, 42,0
90, 0,0, 6.25,14, 6.25,-12.5

it was saved as "LVT 6.25x42 33% Offset"

Thanks for the assistance!

Try it without the pen-down/pen-up numbers at the end of the first line. I think I've seen the same problem before -- that it doesn't like a zero-length pen-up, which in any case should be negative. Those lines are continuous anyway -- no need for pen-down/pen-up.

*LVT 6.25x42 33% Offset, LVT Pattern
0, 0,0, 14,6.25
90, 0,0, 6.25,14, 6.25,-12.5

You might be interested in RunningBondHPG.lsp, >here<, which can construct the pattern definition of something like that for you. You just give it the element size and the amount of stagger you want.

Is this the error you get, or is it something else? You never quite show it

Just change the name of the pattern and file, see attached inside the ZIP file, it works great

I don't get any errors, the hatch pattern simply won't appear in my custom hatches via the folder path I put it in. Once I put the custom hatch in the folder, it will be available upon opening autocad next. This custom hatch file won't even show up in autocad as an option to use.

See the other half of my earlier reply: works great after the change

A week or so ago, turns out it was a file naming convention only TILE_3x12_33Offset.pat

Ah, yes. In a pattern defined in its own file, the file name and the pattern name must be the same, so if something like their % sign is not allowed in both AutoCAD Hatch pattern names and computer File names, it won't fly.

The file you gave, I put into my custom hatch folder, and it doesn't appear in autocad still. I wish I could screenshot the menu to show that it is not there, but the menu is dependent on you staying in the hatch command.

This solution did not work, as for the running bond file, that is extremely in depth and a little confusing to follow, I don't know where to start to edit it...

Okay, here is a file of a custom hatch pattern created that WORKS...I'm literally doing the same thing as this file yet I am met with consistent issues.

You have to choose CUSTOM

Your keyboard has a PRINTSCR or PRINTSCREEN or PRT SC button, use that then paste into AutoCAD or MSWord or Windows Paint.... .

When i changed the Hatch and file name to LVT, it worked with no issues.

There is no

.25

in the name

That is because the size is 6"x36" not 6.25"x36". I am trying to create a 6.25"x42" LVT pattern. I should be able to follow the custom hatch instructions I have been using with no issues. I gave that file as an example to show that I name things with a % and save them with a % and it works.

LVT is in the name and the file name for the original hatch I created. here is what I am trying to create and its not working.

It may have not worked because of invalid characters in the pattern / file name.

The running-bond file is not for you to edit [except for the file path] -- it's not a pattern, but a pattern generator. Load it, enter the RBHPG command name, and answer a few questions, and it will build the pattern definition and the file for it. [But do the editing needed for the filepath you want it to use.] It made the attached in seconds. You have your choice of whether the 1/3 stagger goes left or right.

It comments that [the reason for @pendean's post about this] a period is not accepted as part of a pattern name, and / is not in a file name, which is why it substitutes other characters, so that the same name can serve for both [they must match].

When i change the name to just "LVT" the hatch works (both of them). There is something with the name that its not happy with.

Again, it's the period/decimal-point in it.

agreed. Just trying to illustrate that changing the name is a simple way to nail down the cause.

something else that may be causing you issues is adding the last line break. Make sure that you have a carriage return to the last line in your file. You cursor should be on the next line with no chars in it.
