Invisible Linetype Not Displaying Correctly

    I have long used an 'invisible' linetype which only displays a dot at the
    vertices, for boundaries of hatches:

    *INVISIBLE,. (Dot at endpoints only) .
    A,0,-100000

    Command: (tblsearch "ltype" "invisible")
    ((0 . "LTYPE") (2 . "INVISIBLE") (70 . 0) (3 . ". (Dot at endpoints
    only) .") (72 . 65) (73 . 2) (40 . 100000.0) (49 . 0.0) (49
    .. -100000.0))

    However recently in modelspace the linetype always shows as continuous,
    while is paperspace it displays correctly.

    Any ideas? Ltscale = 4, Psltscale =1, toggling either doesn't affect it.

    Thanks,

    Dan

    I dunno about the display of the ine, but wouldn't it be easier to just place the line on a non-plotting layer?

  3. You might check VIEWRES, which controls not only the segmenting of curves,
    but also the display of non-continuous linetypes (they display as continuous
    if VIEWRES is low enough in relation to the display size and zoom factor).

    Because it is easier to keep the hatch & boundary on the same layer &
    minimize the chance of them being separated/nonassociative. Plus I like
    WYSIWIG drafting, not having to 'know' that line won't plot.

    (Rant - why can't acad just have a polygon solid fill object with a property
    of edge display on/off, not this cludge of association + the usual moan of
    my 10 year old cad program had this feature...)

    Thanks for the suggestion, but it didn't seem to affect it. Weird this just
    started a couple days ago.

    Well the edges of the hatch itself arn't displayed, but rather the elements that were used to define the hatch. Associative hatch is associated with those elements for ease of later manipulation. (if you edit the road the hatch changes with it)

    And you can create non-associative hatch without boundaries.

  7. Here's my approach to knowing what lines won't plot. For most ordinary
    drawings, we only use the first 7 colors for any "real" (that is,
    to-be-plotted) drawing information, partly because it's a lot easier to
    check pen assignments in plotting, if you don't need to look beyond those.
    Seven different line weights gives plenty of range for our purposes. But it
    has the other advantage that I can then make a non-plotting layer (which I
    often do for building or room area polylines, occasionally for hatch
    boundaries in unusual circumstances, or for commentary to myself, etc.), and
    give it a color that's easily recognizable as NOT one of those first 7 (like
    an orange shade, or a purple noticeably darker than magenta, or something).
    It's a way of keeping non-plotting information easily readable, and pickable
    (which could sometimes be a problem with Dan's Invisible linetype), but
    easily recognizable as something that won't be on paper.

    One of my disappointments in A2K4 is that in the pull-down Layer list on the
    toolbar, the plot/non-plot symbol doesn't appear as it did in A2K (you have
    to call up the full Layer dialog box to see it). So if there's any
    question, now you can't just pick on an item on a given layer, and look at
    the Layer thing in the toolbar to see whether that's a plotting layer.

  8. Hey,

    check the objects linetype scale thru' properties.
    ltscale of 4 indicates a 3":1'-0" scale of maybe 1 1/2":1'-0" - if the line
    you are drawing is long - it will appear solid unless you zoom in quite a
    bit.

    is regenmode set to 1?

    what is your zoomfactor in the viewport?

    if you're zoomed 1/48XP then to match the way it appears in pspace, your
    ltscale should 4*48

    Consulting - If you're not part of the solution, there's good money in
    prolonging the problem.
