    Can't find anything in knowledge base. what will result in longer paper
    space regen time, a whole bunch of x-refs or a whole bunch of viewports? I
    need the tech answer like "more viewports take longer to regen because...."
    I think its viewports, but couldn't say why

    thanks

    Might want to do a search through the manager's group. This topic came up
    within the last month or two. Their answers may be able to help you.

    yea i wrote it, but the response were inconclusive. jamie had the best but
    no "why"

    "Seriously it depends on the size of the xrefs (load and regen), and numbers
    of viewport (many views with a lot of text and hatches). Viewports can
    overwhelm ram (complete display list for each viewport plus the layout tab).
    When that happens windows has to page the memory to the hard disk. That's
    when the pc really begins to slow." -jamie


    "Viewports can overwhelm ram" is what i am looking for

    hmm, if i have a sheet of say 20 details drawn in MS as normal with 20
    viewports, will this take longer to regen or open than the same set of
    details reference into paper space.
    one is all viewports the all ref's. I'm trying get a tech to answer "the
    viewports are slower to regen because" or vice versa.

    jamies is good but is referancing subject to the same ram problems.

    <<what will result in longer paper space regen time, a whole bunch of x-refs or a whole bunch of viewports?>>

    Longer than what??

    There's little difference, on my machine, in either.
    I have a detail sheet with 31 viewports, regens (regenall) in just over 1 second.

    Another file has only 5 viewports with 7 xrefs, each xref averages about 11MB, It regens in just over 1 second.

  6. I already answered once, try it again.
    Depends very much on what you use most.
    A drawing with one viewport and 20 heavy xrefs might take to regen just as
    long as a drawing with 20 viewports and 1 small xref.
    Generally: a viewport contains the entire drawing.
    So if you have a 4mb drawing and use 5 viewports, you are actually (in PS)
    using a drawing of 5(ps)+1(ms)=6x4mb=24mb.
    Thats my experience, opinions may differ.

    Short:
    if it takes a cup of coffee before your drawing has loaded in MS, you have
    20 viewports, you can drink a can of coffee when switching to PS. Logic or
    not?

    You cannot say "viewports take longer because ..." simply becasue it matters
    what you have in MS and how many viewports in PS.
