Problem while redefining a block

[moshira_hassan]

HI ....
sometimes when I try to redefine a block by adding objects to it I got this message :
" Cannot save back changes because objects in the working set refrence objects outside the working set . The redefine session is still active. Press F2 after dismissing the dialog to see the list of missing references "
and when i press F2 i see nothing ..... what is happining here:banghead:

Moshira,

Sounds to me that during the REFEDIT process
you may be accidentally selecting items that are not
part of the original block definition.
And or you are not dismissing the dialog by saving and closing the REFEDIT
session prior to editing other objects in the drawing.

See the following: http://usa.autodesk.com/adsk/servlet/ps/item?siteID=123112&id=2874139&linkID=2475323

Ok, I ran a few tests here Moshira,
and the only tip I can suggest is to
set your SNAPBASE very near your working set prior to
performing the refedit operation.
