Topic: Lt scale

[Bob Garner]

I do a lot of structural steel detail sheets that contain different details drawn to different scales.  To accomodate this, I draw the details at 1:1 and x-ref them to a full size title block sheet.  The ltscales of the details have to be multiplied by the reciprocal of the x-ref insertion scale to plot correctly.

When working (in model space), we have LTS set according to the scale of dwg.  When plotting (papaer space), we use script to set LTS to .5 before sending.  Psltscale is always set at 1.

PSLTSCALE is generally set to 0, that is because some of our drawings must be plotted from MS ... and as such, switching between the two is more a headache than simply setting it once and leaving it alone...it works and is efficient, and actually increases productivity because the person doing the drawing does not have to worry about the settings at all... it is all automatic...

Somewhere on this board is a routine that toggles ltscale & psltscale based on a "tab" reactor.  I don't remember who wrote it or where I got it cuz' the machine crashed and I had to re-create it, but here's what I use.  Some guru here could probably make it a lot slicker.

Code: [Select]

(defun ChangedLayout (reactor layout / )
  (if (/= (nth 0 layout) "Model")
   (progn
      (setvar "ltscale" 0.3333)
      (setvar "psltscale" 1)
    )
  (progn
    (if (> (getvar "dimscale") 12)
      (setvar "ltscale" (/ (getvar "dimscale")3.0))
      (setvar "ltscale" 40)
    )
      (setvar "psltscale" 1)
    )
  )
)
(if (not *LayoutLTS*)
 (setq *LayoutLTS* (VLR-Miscellaneous-Reactor nil '((:VLR-layoutSwitched . ChangedLayout))))
)

Hmmm.. interesting... that would solve the issue..

Try this link.  It might help some cases.

Here's the one I got from someone on the Autodesk forums...you have to regen after you switch layouts, but it's still a great timesaver.

Code: [Select]

(defun   ChangedLayout (reactor layout /)
   (if (= (nth 0 layout) "Model")
    (setvar "ltscale"
          (*   (if   (= (getvar "dimscale") 0)
              1
              ; else
              (getvar "dimscale")
              ); if
            0.5
            ); *
          )
    (progn   (setvar "ltscale" 0.5)
         (setvar "psltscale" 1)
         )
    ); if
)

(if
  (not *LayoutLTS*)
    (setq *LayoutLTS* (VLR-Miscellaneous-Reactor nil
      '((:VLR-layoutSwitched . ChangedLayout))
    )
  )
)
