CEED 2012 Part-A Q-34
I have previously mentioned that the figure has 16 faces, option (C)
As a justification I am attaching the numbered faces as solution
The NX-6 model of the problem. Based on Rohit Chainani's approach I made a CAD model in UG NX-6. Here is the solution for the same.

Hi Prasanna, Thank you for explaining it so well. Totally clears out all the ambiguity. I know this Q seems very easy, but its a tricky one, I feel.
I wanted to be sure that I was visualizing it correctly so I created the block in Pro-E, sounds stupid, but I just wanted to be very sure about it. Well, to my surprise, when I selected all the faces 1 by 1, I was surprised to see a total of 15 selected items.
Observing the selections I understood that Pro-E took faces 3 & 8 (as indicated in the paint image above) not as two different faces but a single face. Hence making a total of 15 faces. Although ProE seems to have the right logic, I am not fully convinced as to what is the right answer. Is it 15 or 16?
Please help.
(One more thing, its the 34th Question, doesn't really matter though)
Hello Rohit,
I also made a model on NX-6 to verify your claim. UG is showing these two faces as different, but that is only when I use the 'Unite' command to merge the separate bodies.
Actually, faces 3 and 8 are different, because they are separated at least by one edge.
Thanks, for pointing out. i corrected the numbering of question and included a better picture of the question paper
This time the exam is online, so the images wont be printed, they will be displayed at a good resolution on screen.
Really appreciate your efforts. The Wire-frame model has definitely solved the confusion. Looks good (wish we get such photos this time) & so simple that it almost makes me look dumb. :-/ What went wrong when I did it was, I didn't unite the bodies, may be that is why it showed 3 & 8 as a single face. Silly me.
So the correct ans remains 16. Thank you for your quick responses & elaborate sketches, helped me a lot!
Hope you would do the necessary changes in the solution set soon. Thanks again.
Hi sir,...firstly let me thank you for your effort.
But i have a doubt regarding the answer as 15 or 16. got cleared it.
hello. quick question.
it seems to be that a candidate may gain admission into the M.Des course through GATE as well. Would it be advisable to attempt both, ie CEED and GATE?
Yes, i feel it is advisable for a candidate to appear for both GATE and CEED, to maximize the chances of selection. GATE score is considered only for IIT-K and IISc
okay. thank you! :)
my first preference is IISc!
hi woyzeck,
Hope you get selected :)
I can guide you even better for IISc interviews because I did my masters from there :)
hi Prasanna,
is it wise to appear for gate too for going for m.des degree.or concentrating fully on CEED is enough .
thank you!
also, i was wondering about the fee structure, and the possibility of getting a scholarship/grant.
do they have scholarships for this course at these institutions?
I would suggest to use a rough orthogonal projection of each side, top and bottom to count the number of faces. Just that you'll need to ensure that you count the faces on the inside at the end.

Hello ashish,
Its a good idea to appear for GATE as well. It increases your chances of selection in IISc and IIT-K , since only these two institutes consider GATE score!
Hello woyzeck ,
you would be granted a Ministry of Human Resource Development Scholarship on securing admission to any IIT ot IISc, so relax
Hello Kartik,
I really appreciate that you thought about a novel point of view!
I dont consider use of orthographic projections a very good option for two reasons: First, unless you have a strong base in mechanical engineering, projections are pain in a**. Second, you will waste some time in converting the figure to front view side view, etc. And that too if you make a mistake reading the views, you are done!
One more point i feel is, this figure is easy to convert into such orthographic projections, since it has all edges at 90 degrees, but it might be complicated to convert a compound figure into it.
Hello Sir,
I hav a doubt regarding 2 courses can u plez clarify it 4 me. i have done wid Mechanical Engg now. i get 2 know that we have options 2 join 4 Mtech - Machine Design and Mdes....whatz the difference between the 2 courses....??
Hello Arjun,
I will clarify your doubt with rather a crude answer. Industrial design deals with looks, function and human factors associated with any product, while machine design deals with strength, engineering function and production of a part of machine or equipment.
You can look into the course content of any IIT, and specially IIT-B for further clarification
Best luck :)
