Create an hatch

When I wanted to make my own hatch pattern I read through the AutoCAD help section under the Customization Guide - Linetypes and Hatch Patterns. It got me through it. Good luck.

thanks Emo

Its possible with Notepad - but have fun :-(

More sensibly try ww.caddalog.com (might only be one "d"). You should be able to d/l a shareware proggy from there.

What type of hatch pattern are you trying to create? I'm sure there are enough talented people in this newsgroup who would be willing to help.

It's fully explained in the Customization Guide section of HELP. However, it can be much easier if you can find an add-on utility that does the job. Do a Google search for "BoobyHatch" or "bbyhatch" -- it's a tool that's been around for a while, and works quite nicely. ___

Did you get the hatch I sent you? Open it up with Notepad and take a look at it for an example.

Hi! Is like the diamond one but instead of diamonds I need small circles, I can arrange a jpg for anyone willing to help. Its because its a default hatch for restoration. Thanks Emo

Hatch patterns can't contain circles or arcs. You'll have to simulate curves with short straight-line segments. Here's one you can try, if you wish:

We are also looking for a hatch pattern of a "dimensional shingle" I have talked to a few different mfr's but none have one to match their product. Has anyoune out there created one or know where to get one? Email or post if you can help....

Thanks,

Download hatch pattern from

it up with Notepad and take a look at it for an example.

Extract from my FAQ Page at

===================================================

Where Can I find more Hatch Patterns

===================================================

You will find Hatch Patterns available at the following web sites.

to mention just a few, or you can purchase my AutoCAD Utilities Collection CD Rom which already has them on. If you want to see whats available out there I've catalogued them and produced an Adobe e-book for each collection see my download page.

-------------------------------------------------------------------------------- How easy is is to create your own hatch pattern ?

--------------------------------------------------------------------------------

For more complicated hatches you could try bbyhatch.lsp but it does make large files.

Take a look at

they have a tutorial system called Tailoring AutoCAD by Ralph Grabowski which I found useful for many things including customised hatching. I didn't find it so much as hard as fiddly.

You can also look at the AutoCAD help file, here is an extract:-

Defining a hatch pattern requires knowledge, practice, patience, and a text editor. You can add a pattern to the acad.pat library file or store it in a file by itself, in which case the file name must be the same as the pattern name. For instance, a pattern named PIT would reside in the pit.pat file.

Regardless of where the definition is stored, the pattern has the same format. It has a header line that looks like this:

*pattern-name [, description]

It also has one or more line descriptors of the following form:

angle, x-origin, y-origin, delta-x, delta-y [, dash-1, dash-2, ...]

For example, a pattern called L45 that hatches with 45-degree lines separated by a spacing of 0.5 is defined as follows:

*L45,45 degree lines

45, 0,0, 0,0.5

This simple pattern specifies that a line is to be drawn at an angle of 45 degrees, that the first line of the family of hatch lines is to pass through the (0,0) drawing origin, and that the spacing between hatch lines of the family is to be 0.5 drawing units. L45 is the name of the pattern, and the description field is the optional description of the pattern displayed by the ? option of the HATCH command. (If you omit the description, do not include a comma after the pattern name.)

Each line in a pattern definition file can contain up to 80 characters. AutoCAD ignores blank lines and text to the right of a semicolon.

------------------------------------------------------------------------------------------ A tip when defining your own hatch pattern is to define one line pattern at a time and when that is right add the next

------------------------------------------------------------------------------------------ There is also a tutorial called Customize AutoCAD crosshatch patterns by Bill Fane to be found in the Learning Curve section of CADALYST

------------------------------------------------------------------------------------------- Hope this helps
