Topic: Annoying "Scaning the drawing" when removing VIEW's

[kruuger]

hello

i'm removing VIEW's inside my program (under dcl). with this code:

Code: [Select]

(defun ads:001_RemoveUcsView (Mode / adoc)
  (setq adoc (vla-get-ActiveDocument (vlax-get-acad-object)))
  (foreach %1
    (list
      (vla-Get-Views adoc)
      (vla-Get-UserCoordinateSystems adoc)
    )
    (vlax-for %2 %1
      (if
        (and
          (if Mode
            T
            (not (member (vla-get-name %2) (mapcar (quote cdr) (mapcar (quote car) *lst))))
          )
          (= "001_MVP_" (substr (vla-get-name %2) 1 8))
        )
        (vl-catch-all-apply 'vla-delete (list %2))
      )
    )
  )
)every time when i run this code autocad start processing something in modemacro line (Scanning the drawing...).
with larger drawing it is very annoying and time consuming.
is there any trick to avoid this ? command is fine before dcl but not when i'm inside dialog.

thanks

i think i will temporary close the dialog, delete VIEW's with command and restore dcl state.
it will be 100x faster than VLA approach.

Does the drawing have any indexing turned on, or are you running a third-party plug-in which may be reacting to certain drawing changes?

Then again - should you be deleting items from a collection as you are iterating it?

i think it is a bug. just create few views (10-20) a try this:

Code: [Select]

(vlax-for % (vla-Get-Views (vla-get-ActiveDocument (vlax-get-acad-object)))
  (vla-delete %)
)

i try on few station with different configuration, cad version and autocad always "Scanning the drawing"

For me, using your drawing, the  "Scanning the drawing" is shown .. but it still processes very fast.

For interest in your production drawings is a layer filter set or are you showing ALL ?

apparently SHOWLAYERUSAGE other than OFF also affects the process ( from my quick reading)

Personally I wouldn't delete objects from a collection while iterating the collection ; I'd make a list of the objects I want to process.
This may be just my paranoia kicking in 'cause I don't recall how vlax-for works internally.

this VIEW issue is related to my program (still looking for someone):

if you see new sample (only 4 layout, maybe 30 views) scanning is very annoying and this is rather very small shop drawing.
i think the same problem is with deleting UCS.


BTW Kerry, i spoke with G.S. very nice guy. maybe he can take this.
