ADCADD_ZZ ignored". *Invalid*

[aqcadd]

I am working in Land Desktop 2007 and trying to insert some blocks from 2004 files, and I receive the following message "duplicate definition of block ADCADD_ZZ ignored". *Invalid*.

I am unable to insert the file into the drawing. Does anyone know why, and if there is a fix to this problem.

I don't think one message has anything to do with the other.
The duplicate block def message is just an informational message, but the *invalid* could mean a few things. Maybe there is a block in the current drawing with the same name as the drawing you are trying to insert?

If Audit and Purge don't clear up the issue, try using the Rename command to rename the block in the existing drawing before you attempt the import.
If it is still considered "invalid", perhaps you could try to redefine it - there may be something in the block that's :screwy: and redefining it as, say, a simple rectangle or something, might do the trick.

I wouldn't rename "ADCADD_ZZ", that will foul up your Land Desktop drawing.
The duplicate block message is just FYI, and is not an error.

Okay, then, let's see...how about audit and purge and any other cleanout possibilities in the incoming blocks before attempting to bring them in. Also add -Purge, R into that mix.

Actually, there is a lisp routine you need to run then select previous, erase then resave the file to get rid of the ACADD_ZZ block.

I found the info over on the autocad forums and have the information at work. Email me please to remind me to post the answer.

I don't recall where I found this but it does work.

Important: If you are using Softdesk software, note that the ADCADD_ZZ block consists of project information and should not be purged from the drawing.
1. Switch to paper space (TILEMODE = 0).
2. On the command line, type (ssget "x" '((2 . "adcadd_zz"))) and press ENTER.
3. Type erase and press ENTER.
4. Type p and press ENTER to select and erase the previous selection set.
5. Type purge and press ENTER to purge the ADCADD_ZZ block from the drawing.

Or LDT.

Thanks. I found the same routine online - it does get rid of the adcadd_zz block in the drawing, but when I insert another block (file) it comes back and shows me the same invalid message. The adcadd_zz block is also in the files I am trying to insert. I run the same routine in those files, it removes the adcadd_zz block but when I open the files again it reappears.

Every drawing that's ever been part of a Land Desktop or Softdesk project will have an ADCADD_ZZ block. There are no entitites in that block, eg it's an empty block definition. There is xdata attached to the instance of the block in the current drawing that holds the project link information.

Delete it if you want, and you'll lose the project data. As soon as you re-open that drawing in a Land Desktop session, it will be recreated.

The incoming definition is simply the same empty block definition when Autocad ignores it, you really just need to ignore it to yourself. It's not an error message, and it's irrelevant to anything except LDT. And LDT will only care about the instance existing in the drawing that has it's particular data attached.
