Program to detect cheating in AutoCad

[Mrdark]

I am looking for a program that detects cheating with autocad? Ex. Copying one persons drawing and calling it their own. I know Universities and other technical schools have such a program.

Thankyou,

MrDark

Humm, that's interesting. I must admit that I haven't heard of that before. One of the great joys and efficiencies in using a CAD programme is the ability to "share" content.

I don't use any such software in my teaching because it's usually obvious if this sort of thing has been going on - in fact, I often run group projects where a student team will have to work together and share data since this is much more of a real world situation.

What's your particular concern?

well we have been facing the similar problem in our college. But we had no other option than ignoring it!!

ask your students to turn on the log file and ask them to submit the log file with their work. ~ and award a percentage of the mark to the log file ~ that way, if they don't submit one, they lose a mark or two !


I seem to remember this being discused in depth before ~ wasn't it on this forum ?

other than that, the only thing you can do is to find an error and see if this error is replicated on other drawings

this is what we do to catch the cheaters!

Check the TDCREATE variable. They CAN NOT be the exact same unless it IS the same drawing

If you are teaching introductory or maybe even intermediate students, I would think XDATA would be good tool. It can be fairly difficult to remove or edit for a newbie.

At the end or start of each session, check that each entity has the repective author's name or ID. Radmonly during the session and at the end of the session, add the author's name to new entitites

(defun add_xdata_str (e a v);;;EName APPID String_value
  (and (not (tblsearch "APPID" a))
       (regapp a))
  (and (= (type e) 'ENAME)
       (= (type v) 'STR)
       (= (type a) 'STR)
       (entmod
         (append (entget e)
           (list
            (cons -3
             (list
              (cons a
               (list (cons 1000 v))))))))))

(add_xdata_str "Author" ename (getvar "LOGINNAME"))

or maybe (getvar "_PKSER") if the software was installed from individual disks.

Taken from CadResource.com

TDCREATE.ZIPCompares autocad drawing files for same TDCREATE systemvars. If two or more files have the same TDCREATE date list these filenames. Useful for AutoCAD course teachers to check if any two students started with the same drawing, somebody used anothers dwg as prototype, but it cannot be checked if someone inserts another dwg in to his. (my students aren't that good with blocks (Will come in the next version, it is possible by checking the handles) New with V1.3:bugfix: date conversion corrected, error after the comma filespec functions removed

you could give a short in class quiz that asks what command they used to draw a certain part of the drawing. you could also check to see who has bak files and who doesn't and if the bak are copies. you could also tell them how long it should take them to finish a drawing and then ask them to write the actual amount of time on the drawing. If the times are to short or to long or exactly the same then you could wonder if someone is cheating.

unfortunately with every attempt to catch cheaters there is a way to avoid getting caught.

My teacher at tech spotted every little error we did on cad.

On the acad city&guilds 4 the one with big house, his eyes where all over it from start to finish and he always asked questions and helped us out.

Infact on all projects at college he was there helping out and new what we where doing at all times, Again eyes all over what we where doing.

There was no way you would even think about pulling the wool over his eyes.

Now this is no program stop cheating....but it does stop cheating.
