Set PSLTSCALE to X in every layout

[ibach]

I needed to set PSLTSCALE to 0 in all the layouts of a drawing then I found:

 

(foreach lay (layoutlist)(command "_LAYOUT" "_Set" lay "PSLTSCALE" 0))

Which took an hour to finish on my DWG (has many layouts) and I'm under the impression that autocad actually opened each layout, regenerated, applied PSLTSCALE=0, regenerated again and so on.

Is there a way to speed up things like apply PSLTSCALE=0 with regen disabled,

than when all done do REGENALL.

 

I've also found this:

 

; PS0 definition
(defun c:PS0()
 (foreach lay (layoutlist)
   (command "_LAYOUT" "_Set" lay "PSLTSCALE" 0)
   (command "_pspace")
   (command "_zoom" "extents")
 );end foreach
);endPS0 (c:PS0)

I do not understand why

(command "_zoom" "extents")

was used.

 

Another thing I'm not sure about is what happens when one layout has multiple viewports, with both ways of changing PSLTSCALE is _pspace recursive in all viewports io an layout, by itself, or it just changes first viewport for "foreach" is used for layout, but not viewport in layout.

 

One more thin to add to this lsp would be reloading of all linetypes at the end.

If you can find how the effect of said system variable is set into layout's associated list, you may create a selection set with all layouts from drawing and parse this one instead to adjust the associated lists.

(ssget "_X" '((0 . "VIEWPORT")))

i'm afraid that i'm not smart enough...

or maybe i should just catch some sleep... but you are absolutely right.
