If you open the attached dwg file, you'll see two instances of the SAME BLOCK.
Now edit the one on the left. There is NO DATE attribute.
Now edit the one on the right. There IS a DATE attribute.
EDIT: This is 2012.
Solved! Go to Solution.
And just to confirm that it is in fact the same block, I opened it in BEDIT and drew a line across the drawing area. When I closed BEDIT, the line was in both blocks.
Command:BATTMAN -> Sync
EDIT: Is not impossible, one of the blocks was edited with BATTMAN command in another dwg, the Date attribute was removed, then imported into the current using copy/paste...
Attribute references can be unique in each block. If they were not, then separate values for the same attribute in different block instances wouldn't work. In most cases, it doesn't happen since the program takes care of it. But it can be gotten around with relative ease e.g. attribute color can be individually modified through the attribute editor.
Hmmm. Interesting. Thanks guys.
I knew that attributes could be different -- that's the whole point of an attribute -- but I always thought that EVERY instance of the block would have the same definition. To me that included all having the same attributes which would of course have diff values and possibly different formatting (font, color etc). When I saw that one of the attributes was completely missing, I thought it was really strange.
