Wblock and filters...Help!!!

Generally using Wblock to "block out" items from a file will result in all
filters from the inital file also being attached to the second file.

Whilst in some cases this is "irritating" I have a particular file that I
need to Wblock a portion from and DO require the filters to be taken with
it. Unfortunately this refuses to happen on several different PC's.

I guess there is a "system variable" that magically turns off the ability to
extract the filters within individual files.

Anyone know what it is, or any help on solving this problem? If so it may be
useful to stop unwanted filters being taken with Wblocks in the future.

Many thanks in anticipation.

If you mean the Named Layer Filters then there is no way to stop them from
propagating themselves in releases prior to 2005. I don't have 2005, but
there may be such a variable in that version.

For versions 2000- 2004 delete the unwanted filters in your drawings, load
this lisp and type: filtrdel

(defun c:filtrdel (/ names)
(vl-Load-Com)
(textscr)
(princ "\nRoutine to delete all but the specified Layer filters. When
entering filter
names to retain, wildcards are allowed. i.e., entering \"zz*,xx*\" will
delete all filters except those beginning with zz and xx.")
(setq names (getstring "\nEnter filter names to retain, press Enter for
none: "))
(vl-Catch-All-Apply
'(lambda ()
(setq dicts (vla-GetExtensionDictionary
(vla-Get-Layers
(vla-Get-ActiveDocument
(vlax-Get-Acad-Object)
)
)
)
)
(vlax-for dict dicts
(if (and (= (vla-get-name dict) "ACAD_LAYERFILTERS")
(> (vla-get-count dict) 0))
(progn
(vlax-for filtr dict
(if (not (wcmatch (vla-get-name filtr) names))
(vla-delete filtr)
)
)
)
)
)
)
)
(graphscr)
(princ "\nSpecified layer filters have been deleted.")
(princ)
)

 

In 2005, named layer filters are not carried along with copy/paste,
wblock/insert operations.
