Topic: Batch Determine if DWG Has Reference File(s)

[encepta]

I have a ~2000 unique DWG's across various directory locations.

1. I need to know how many of these have reference file(s).

2. Has anyone tried to do something like this before? I.e. checking for reference files via LISP function, API, Python, etc.?

3. I would like to do this programmatically, but I need to know if the 'Check for Reference File' is even possible?

Cheers,
Henry

You should be able to use any COM aware language, along with the e-Transmit API

There’s a sample here in C# at
https://adndevblog.typepad.com/autocad/2012/06/using-e-transmit-api-in-net-to-find-external-references-in-a-drawing.html

e-Transmit API should pick up xrefs, datalinks and such

Getting a list of all the reference files is easy enough with lisp too.

Code - Auto/Visual Lisp: [Select]

1. ( (lambda (/ entry)
2.     (while
3.       (setq entry (tblnext "block" (not entry)))
4.       (if (cdr (assoc 1 entry))
5.         ;; check to see if it has a path
6.         ;;
7.         ;; if it does..
8.         (print entry)
9.         ) ; if
10.       ); while
11.     (princ)
12.     )
13.  )
14.

Very nice. Thank you.

There's also the Reference Manager tool that comes with AutoCAD. Look in the start menu. Just open a folder of files and it will show you all the files being reference and by type. If it finds broken xref links, you can batch fix them with this tool.
