Laser printer line weights

Discussion in 'Pro/Engineer & Creo Elements/Pro' started by Sean Kerslake, Sep 9, 2004.

  1. How do I control the line weights for geometry, dimns, etc. when using a
    laser printer?

    Cheers, Sean

    :

    Plotters and printgers used to be worlds apart and there were special settings in
    programs that used plotters, like Pro/e, to deal with pen line weights. Plotters
    were pen plotters and had actual pens of certain colors and weights. Line
    thickness is still being controlled in Pro/e, not with modern GUI designations
    like bold or extra bold or fine, but by pens and weights.

    Internal to Pro/e, it has 8 'pens' available, with line weights in a range from
    1to 16. I don't know what the actual measured thickness of 1 or 16 is (the range,
    that is). But, if you set pen1_line_weight through pen8_line_weight to some
    number, 3 for example, to test and vary, systematically, you should be able to
    figure it out.

    Additionally, there is a feature available for controlling line weight, style
    (solid, dashed, dot), angle and color, called a pen.tbl which is a simple ASCII
    file with values in a format that will tell the interpreter, that for a certain
    type of line style in the model, print with a certain pattern of lines. The
    pen.tbl file contains the line pattern definition, including weights, etc. and
    passes this to the post script interpreter. If you don't need to vary line styles,
    colors, etc, you may never need a pen.tbl file. Check the Help filles for pen or
    line weights.

    : Hmm. Maybe PTC thought that since the target market for Pro/E
    : is engineers, pen numbers and line weights would be received
    : better than Family Size ! Jumbo ! Bigger than Jumbo ! Super-
    : Extra Double-Jumbo ! or the all-time favorite, WouldYouLiketo
    : UpgradeThattoSuperSize ?

    : could add a little marketing pizzazz to that boring old-fashioned
    : PTC interface :)

    Ummm, I think the point was that pens and pen weights is ancient technology of pen
    plotters. This has absolutly no relevance to post script printing on ps enabled
    laser printers. The control language is outdated, leaving Pro/e in the AutoCAD 2D
    'plotting' era. I know you got past ACAD plotting a couple years ago; surprised to
    see you apologizing for Pro/e's adherence to this decript, ancient, obsolete
    technology as some kind of "standard" when, in fact, it bases its printing
    technology on Postscript.
