Discussion in 'AutoCAD' started by Emiliano Della Bella, Nov 14, 2003.

  1. Hi everyone!
    I was wondering how can I make a new hatch. Do I need a special proggy or is
    it pssible with the main autocad program?
    I have both release 2004 and 14.
    Thanks

  3. 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.

  4. 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

    Where Can I find more Hatch Patterns

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

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

    http://www.caddepot.com

    http://www.cadalog.com

    http://www.cadsupport.co.uk/cshatch.htm

    http://www.hatchpatterns.com

    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 www.upfrontezine.com 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.
