linetype and linetype scales

Discussion in 'AutoCAD' started by David McReynolds, Dec 3, 2004.

  1. I have been drafting using autocad for over 10 years and I have always
    adhered to the standard of using ltscale of .5 and a psltscale of 1. This
    allows you to have different scales on 1 sheet drawing (i'm sure this is not
    anything new to anyone) My new employer has a setup where they set the
    ltscale at 24 for a 1/8" dwg and 16 for a 1/4" dwg. if you try to do
    multiple scales on 1 sheet you would have to scale the linetypes via the
    properties dialog box. I'm told the reason for this is to not have to change
    the ltscale when going from MS to PS in order to see linetype generation
    when in MS. also so that setting the ltscale back to 96 or 48 is not
    forgotten when plotting. does anyone know of a way to not have to switch
    the ltscale back and forth in order to see LT generation and not have plots
    with solid linetypes?

    Thanks in advance,

    Nope. Your method is the better one. Could your employer live with 16 for a
    1/4" scale and *32* for 1/8"? Then, using your method, PSLTSCALE = 1 and
    LTSCALE = 1/3 (or 0.333). It takes only a tiny bit of customization to
    switch LTSCALE back to 16 or 32 when going back to the Model tab. It
    wouldn't seem to be a big deal, since your employer has folks changing
    LTSCALE for for models to be plotted at different scales anyway. And what
    happens when (or if) there are differently scaled viewports on a single

    If your employer is interested in a compromise, check into the Customization
    group, where this topic has been discussed extensively.

    Search these boards for a layout reactor tool called CHANGEDLAYOUT.LSP. With just a little tweaking you can have it set the ltscale properly when toggling PS to MS to PS

    David's company sounds as though his new job is within an architectural firm
    judging by the 1/4" and 1/8" scales used for plotting. 1/8" scale plotting
    is mostly used for check plots in this venue. 1/4" plots are the finish
    plot size. If you change your linetype scale for the check plots, you will
    not be able to really see what the drawing will look like at the finish plot
    size and you might let something go that you shouldn't or might "correct"
    something that you shouldn't based on readability of text across a hidden or
    dashed line that won't be dashed the same way at a different ltscale. It
    would be wiser just to create a ctb or stb file that gives you lighter pen
    settings for the 1/8" scale plots to better emulate how the plot will look
    at the 1/4" finish plot size. I hope I am making sense.

    I do it the way your employer does it.
    I have a set of scripts to change the ltscale, text height, dim scale ...
    This way it always looks correct while you are drafting it. and a psltscale
    set to 1.
    here is an excerpt from my menu file. It makes multiple scales in drawings
    very easy.

    I also dimension everything in modelspace thats why I have all of the

    One other thing.....

    Switching from model / paper space.
    I use this...

    That's great in R12 or R14, but if you have more than one layout, you're
    probably not going to get the layout you want that way.

  8. I have been using a routine that you can download
    from called Ltype_Switch.
    You can set your different ltcales for model and paper space
    and it will switch those automatically.
