Disabling copy paste from dwg files

[Anonymous]

I am conducting autocad exam , students are sharing files and uploading same document we restricted by layer and block for individual sheets . On the other hand they are copying pasting other dwg files data . Is there any way to disable copy and paste option from other files and enabling copy paste within the sheet

Hi,

>> Is there any way to disable copy and paste option from other files

No, not without development.

I would suggest to give every student an ID, then create specifications based on that ID's.

Eg. radius of circle 1 = (60 - ID) * 0.2

As over here, you can UNDEFINE the Copyclip, Copybase, Pasteclip & Pasteblock commands as long as they don't know about REDEFINE.  If you really mean to enable such operation "within the sheet," that is, within a single Paper Space Layout [or within Model Space], they can use ordinary COPY instead.  If you mean to include copying between different Layouts  within the same drawing file, I don't know a way if those other commands are Undefined.

Not to be that guy, but if these students are going to be using AutoCAD in the near future 90% of what they will be doing for the first bit will be copy and pasting any way.

I'm not sure how much of the process you control but have you considered changing the way you are testing? I really like @Alfred.NESWADBA suggestion. Or perhaps you could provide a starting dwg with 'hidden' dwg elements. Something like a text identifier with a ridiculously small font at a known location. or perhaps a block with hidden attributes with some sort of identification. This would allow you to find out who is copying and who is the source.

You could also try a testing method similar to the way the test for certification. The upshot of those kind of questions is that they focus on using the program and not necessarily creating a drawing.  Below is a question in the style of a certification test;

"(NOTE: THIS NOT AN ACTUAL QUESTION NOR IS IT MEAN TO REPRESENT ANY QUESTION ON THE EXAM)

Given a drawing, draw a circle with a given start point 1 and the radius ending at another point 2. What is the distance from another point 3 to where line 4 intersects the circle. "

From CADnoob.com

So in the example above they are not returning a dwg but a measurement taken from a dwg that they had to create in class. Most of the time these types of question only needed simple geometry so it didn't take much time to draw. So other examples might be like inserting a block at a given point and then exploding that block and taking a measurement from a section of that block to another drawing element.

Past that you might be ale to see about developing a key logger type lisp so that they turn in their dwg with a command history or something along those lines.

You could give each student a base drawing with a little bit of information in it. Call it a template for the test or whatever and email it to them at the start of the test.  All the students would have the same drawing but with something added or changed. Like one drawing starts at 0,0 the next at 0,1 and so on. The issue with this is then it's just more work for you. 

What one of my professors told us was no matter what he does if a student wants to cheat enough they will figure out how. He said we were adults and it was our choice to learn or to cheat. He would tell a story about a student that he thought was copying all his drawings from other students. He talked with the student but the student acted like he didn't know what the professor was talking about even though he never accomplished anything in class lab time.  When that student got his first job he didn't know how to do anything very well and got fired when he couldn't perform. He was eventually able to learn enough at jobs to keep a job, but why learn at a job with all that extra stress when you can learn HERE in class that you ARE PAYING for?  It's funny but the professor basically said cheat if you want, it's only hurting you. I think that is a huge deterrent for kids that actually care even a little bit about their schooling because it puts the burden on them and not the burden on the teacher to try and catch them. The kids that still don't care and cheat any way are probably going to try and cheat no matter what you do.
