Possible to Identify AutoCAD Licence No. Which Created a .dwg?

[killb89]

Hey,

 

I would just like to know if it is possible to establish the creator of a specific .dwg file - specifically the licence number of the AutoCad which created it.

 

 

Thanks,

Why?

 

What would you possibly want to do with such information?

Basically I need to find out if a set of drawings have been produced using our office computers/AutoCAD or if they have been produced elsewhere.

I doubt you could do that.

 

You suspect someone loaded company-purchased software on their home computer without prior permission?

Could you not just check the file owner property in Windows Explorer?

 

If produced on another (non-company) computer, the user's login name will not be the same (although someone could technically make it the same, it is just unlikely).

Enable digital signatures if you want to validate who last saved the drawing. It's built into AutoCAD.

How does one check the file owner property in Windows Explorer?

In Properties>Security>Advanced>Owner? The owner automatically changes if you copy the file to another computer, it dos not seem to retain information on the original owner/creator. Therefore the files in question would cite the company username as the owner even if they were produced elsewhere and later copied across.

For fun (I'm bored):

 

(defun c:LSB () (c:LastSavedBy))
(defun c:LastSavedBy ()
 (princ "\rLAST SAVED BY ")
 (vl-load-com)
 ((lambda (acDoc)
    (prompt (strcat "\n** This drawing was last saved by: \t" 
                    (strcase (vla-get-lastsavedby (vla-get-summaryinfo acDoc)))
                    " ** ")))
   (vla-get-activedocument (vlax-get-acad-object)))
 (princ))

For more detailed information, we could easily utilize the FileScriptingObject Object too :wink:

First, if you're users have the ability to connect from their work computer directly to their home computer (on the same network), you've got bigger issues than *where* are they doing their work.

 

Using Right Click -> Statistics Tab (Windows 7 64-Bit)

 

I've just copied a file from another user's computer to an external drive, checked the properties and they were the 'last saved by' (from my computer). Then copied the file from the external drive to my desktop, and checked again, and the 'last saved by' information is identical.

I always forget to look for LT ; hopefully it will help someone else.

If you are looking for an ongoing solution (not just checking already existing files) my CadTempo software should do what you are looking for. It keeps a continuous record of who worked on what drawing and for how long, listing the person that first created and last accessed the file as well as all users in between. Works with LT also.

 

If a file is copied or moved within Windows Explorer and certain settings are configured the data follows the drawing.
