Have you looked into exploiting the projectname variable?
I looked at it, but it doesn't work in LT and we have a few users on that.

Please help!

We have had our migration over the weekend and every drawing has lost its xrefs path 1000s of the darn things.

What would be the quickest way of updating the xrefs.

For example our project files used to be filed in the I drive, but are now in a P drive. The drawing frames and other protected data was on the G drive but they havent restored that yet, so I dont know what letter that will be.

I can see this is going to be a great week, with lots of posts!

Catch you later

I was hoping to write a routine that looked for an xref, got the path as a string, altered the string with the new path, and then changed the path to suit.

but I haven't got round to it yet, way too busy.  We have about 5000+ drawings with Xrefs detached though.

...to a new server, with a bigger hard drive. The problem is, when we changed server, head office told us that we had to use these drive letters with no exceptions. What was I:\ is now P:\ and as yet I dont know where our G:\ is going to be :realmad:

As you can understand, this is causing loads of problems as none of the drawings have their xrefs attached anymore.

So, I am looking for a quick way of re-pathing the drawings from I, to P, otherwise I am going to be doing this manually for weeks.(like the other offices did!)

Try this on a COPY of one of your drawings ..

I don't use Xrefs, so testing was limited, but seems to not explode in my face :-)

(ChangeXrefDrive "P:") < or whichever drive is new >

Code: [Select]
(defun ChangeXrefDrive (newDrive / xrefEdata)
(mapcar
'(lambda (blockName)
(if
(eq
(logand
4
(cdr (assoc 70 (setq xrefEdata (entget (tblobjname "BLOCK" blockName))))
)
)
4
)
(command "._XREF"
"PATH"
(cdr (assoc 2 xrefEdata))
(strcat newDrive (substr (cdr (assoc 1 xrefEdata)) 3))
)
)
)
(ai_table "BLOCK" 0)
)
(princ)

)

This MAY fall on it's head if you use nested XRefs though ...   :|

The use of PROJECTNAME neatly solves this issue. Previously I hated using it, but I've come to REALLY appreciate it.

I wrote a tool which would open up any number of drawings IN MEMORY, and change the PROJECTNAME setting, as well as strip any hard paths from XREFS.
This runs over several hundred drawings in literally a few minutes.

Unfortunately I can't give this out, however I do have a suggestion. Create a script that adds a certain PROJECTNAME into AutoCAD and add the paths to it. You could do this at AutoCAD startup with a bit of lisp/vba as well (vba is how I do it which reads from a master .xml file).

Then run a script over every drawing which changes the drawing's PROJECTNAME to the newly added one. Since the new PROJECTNAME has your NEW paths in it, your REFERENCE files should be found.

I hope this helps.

Cheers,
Glenn.

Be aware that project naming doesn't work with AutoCAD LT though.
