MS/PS (model space/paper space)

    I was recently hired as a drafting and design manager for an
    engineering firm and prior to my hire, the company decided to start
    drawing by using ms/ps. After this transition, they had quickly
    realized that their linetypes were not plotting correctly. I explained
    to them that they now need to set the psltscale to 1, ltscale to 1 and
    visretain to 1. A few of them have fought with me over this and said
    that they have never heard of that before.

    This is how I have always done it for 8 years and this is how that I
    beleive most people use it in the industry. I also taught part-time at
    a college and this is also the method that I taught.

    I also and understand that the following method:

    psltscale = 0
    ltscale = equal to drawing scale factor
    visretain = 1

    is equal to

    psltscale = 1
    ltscale = 1
    visretain = 1

    My question is.....Which method is used by you and why and could
    someone explain to me the pros and cons of each.

    Thank You

  2. Visretain has nothing to do with scale, this controls whether changes to
    xref dependent data is stored in the current drawing or not, set it to 0
    and every time you reload the xref or open the drawing any changes made
    such as turning layers of or changing their colour will be reset to how
    they are in the xref.
    Scaling is effected by three variables, PSLTScale, CELTScale and LTScale.
    LTScale id the global linetype scale which acts as a multiplier for the
    linetype of all objects.
    CELTScale is the default linetype scale for new objects, the linetype
    scale for an object can be changed in the properties dialog or using chprop.
    PSLTScale is the paperspace scaling, if set to 1 the linetype scales of
    any object appears the same in paperspace and modelspace regardless of
    the scale of the viewport, if set to 0 the scaling of objects is
    relative to the scale of the viewport. If you viewport scale is
    anything other than 1:1 PSLTScale set to one makes life a lot easier, if
    you have multiple viewports with different scales this is the only option.

    psltscale = 0
    This is basically my approach, although I generally don't use
    X-ref's.

    The reason I want psltscale to be 0, is I want the line to keep the
    same appearance all the time. E.g. often if a line is shorter than it
    needs to be to show a particular linetype. I will set its idividual
    ltscale smaller until I get the linetype to show. I don't want lines
    reverting to continuous lines at random.
