How to Hatch in photoshop

Discussion in 'Photoshop Tutorials' started by randomthoughts, Feb 16, 2004.

  1. Would any one please help me to hatch a selection in photoshop. I
    have seen only filling the selected area with texture or patterns..
    but I need autocad like hatching (or filling with dots or simple
    patters like diagonal lines) for engineering drawing.. This should be
    possible with photoshop i think.. would anyone please help me on
    this.. i wonder why photoshop didn't make it bit easy to hatch the
    selections ...

    I don't know how to do it, but it's a good question- I'll be watching for an
    answer.
    Come on you PS experts! Make us proud!

    How is what you want to do different from making a selection
    and filling with a pattern? maybe I could offer an answer
    if i knew.....

    Maybe he wants some kind of vector hatching instead of a bitmap fill?

    Photoshop isn't designed to do vector hatching. It can't produce
    true vectors.

    Where's that guy who wanted to know why you need both PS
    and Illustrator?? This is the answer to his question.

    I guess it could be simulated by creating
    paths with the pen or line
    tool and stroking them with various
    types of lines, but it would be tedious in the extreme....

    Or it could be done with the right font and the text tool,
    which might be a *little* less tedious (need to adjust kern and leading)
    Even ubiquitous fonts like Times New Roman or Dingbats in the
    extended character set have some stuff that could be used for this

    Anyone for ASCII art?

    Not the best solutions, but as kludges go, they work. Frankly, I'd do
    it once and give up and buy a vector app. You'd save enough time on one job
    to justify the cost of something like Xara, if not Illustrator.

    What you are talking about is better done in a vector program such as
    Illustrator

    I know it isn't, I am an illustrator man myself. It was just a question,
    maybe I should have
    added the point about illustrator being better for the job. As we don't
    know what he is
    attempting to do as a whole then it is a bit hard to tell him to use
    illustrator.

  8. OK you need to make some patterns to accomplish this. You can make them on
    the fly, for instance, say you want to "hatch" with dots. Open a new
    transparent file, here you will need to decide what size of dots and how far
    apart, let say for the sake of very small dots, make the new file 5px by
    5px. Use the Pencil tool, foreground black, size 1. Click once in the
    center of the canvas, Edit, Define Pattern, click OK in resulting dialog.
    Now you can fill your selection with that pattern. Here are a few pixel
    patterns I made in CS, put them in your Patterns folder and see if any of
    them will work for you. I hope that it's ok to post a download link here.
    My Photoshop site is a WIP far behind in the line of things I gotta do.

    Did either of you thnk about using paths? Make a selection, then from the
    selection, create a path. With this path you can form it into any vector
    shape you like. From here, you can turn this path into a neat little
    selection, and fill this selection with what you want. It's a very simple,
    yet powerful sequence you can use.

    I will agree though, illustrator will indeed work as well. So would
    freehand.

    I did, see my post, but if you FILL a closed path with a pattern the end
    result is
    no different than filling a selection with a pattern. You still have a
    raster
    pattern. If he wants vectors...anything which uses the words Photoshop and
    Fill
    together won't do it.

    Illustrator, Freehand, Corel, even Sara

  11. This is true and knowing absolutely nothing about autocad and it's workings
    I assumed the user simply wants a pattern which is not included in the
    standard supplied patterns in Photoshop, not an actual vector image. As per
    Joshua's suggestion you could easily create a path with that pattern "fill"
    on a new layer, (the fills are simple pixel patterns on transparent).

    Hey, T! :)
    Hell, *none* of us really knows what he wants, because he asked a
    pretty vague question, and hasn't popped back in to clarify yet.

    Which is why my first response to the original poster
    was basically, "Huh? why is filling a selection with a pattern not
    working for you?"

    The pseudo-vector alternatives were a response to Stuart's assertion that
    Random probably wanted vectors.... but you and I both know that
    trying to make PS act like a vector app is clumsy at best. And if
    someone doesn't have anything better to do than create ASCII
    art......I want that job. LOL

    As to CAD--- CAD is CAD... more like Illy than PS, but more like
    itself than anything else. In some ways brilliant, and in others
    so clunky you have no trouble understanding why they
    export files for enhancement. I'm not a CAD guru, but I've
    had to deal with my share of AutoCAD files from engineers and
    architects for about the last 7 years... (I do my "take a CAD house
    and a digital photo of the site and combine into a 'watercolor'
    rendering" routine for them...)

    Hey, completely OT---do you remember that guy from Binney &
    Smith? (the Crayola guy who had us all playing on the Silly Putty site
    for a couple of days) His stuff began as CAD...and *he* was just amazing
    with it. I've seen a lot of CAD, but his stuff was so cool!!!!
    I wonder what did with that metallic Silly Putty I bought?

  13. Oh yeah I remember that also name the crayon, I remember his cad work,
    reminded me a bit of some output I have seen from 3d stuff. My old neighbor
    used AutoCAD for designing stencils for his airbrush work on motorcycle
    tanks, I always wondered why he would use such a mind boggling program.

  14. Create a grayscale job and convert it to bitmap. In the bitmap conversion
    process, the dialog box will give you an option to use lines and the angle
    you would like them.
    The lines will be spaced according to the percentage of gray that you
    convert.
    Once you have your hatched lines, create a brush from the job and paint the
    areas you need hatched.

    Hatching in photoshop

    You can use the tile function in the filters (Filters, Stylize, Tile.
    you would change the default values to suit. i.e. no offset, or at least a value of 1.
    Apply this to a fully filled path, it will give you a hatched effect. To delete the filled in squares
    just select one of them with the magic wand, right click hit similar and delete. There you have it perfect hatching.
