Detailed component drawing
Deliverable: A machined component drawn in correct projection with a section, functionally dimensioned with fits and surface finish, on a proper title block.
Course
AutoCAD for Mechanical Engineering
Mechanical drafting judged the way a machine shop judges it — correct projection, tolerances that reflect function, and a drawing a machinist can work from without ringing you.

Assembly with bill of material
Deliverable: A five-part assembly with an exploded view, balloons and a bill of material, plus individual detail drawings for each non-standard part.
Tolerance decision note
Deliverable: One drawing where two dimensions carry tight tolerances and the rest are general, with a written justification for each tight tolerance based on how the part functions.

Placement assistance
Every student gets placement assistance — that is what 100% placement assistance means. It is support for all, not a job for all. We do not promise a specific salary, a specific number of interviews, or placement at any named company, and you should be wary of anyone who does.
What is included
- A place in the monthly placement drive, held every third Saturday
- The readiness programme every second Saturday — mock interviews and preparation
- CV review against the specific roles you are targeting
- Portfolio review, so your project work is presented the way a reviewer will read it
- Access to the vacancy pool employers send directly to the Samyak network
- Guidance on which roles realistically fit your background and which do not
- A place in the next drive, with coaching, if you are not selected in this one
What is not included
- Any guarantee of a job, an interview, or a particular salary
- Placement at a named or partner company
- Applying to jobs on your behalf
- Support before you have completed the course and its project work
- Visa, relocation or overseas placement assistance
The machinist is your reader
Every decision on a mechanical drawing is answered by one question: can the person making this part do so without ringing you?
Ambiguous projection, a missing section, a dimension chain that does not close, a tolerance nobody can hold — each of those is a phone call at best and a scrapped part at worst. The course is organised around removing those, which is a different emphasis from learning the commands.
Tolerances are money
This is the module that turns a draughtsman into a designer.
Tolerance everything to a hundredth and the shop quotes you three times the price. Tolerance the wrong thing loosely and the assembly does not go together. Deciding which two dimensions actually matter — because of how the part functions — is engineering judgement, and the third project makes you write that justification down rather than apply a default.
Both projection conventions, always symbolled
India uses first angle. America uses third. You will meet drawings in both.
A drawing read in the wrong convention produces a mirrored part, which is an expensive and completely avoidable failure. Every title block you produce here carries the projection symbol, without exception, because the one time it is missing is the time somebody guesses.
Where 3D takes over, and where it does not
Modern design offices model in SolidWorks or Creo and generate drawings from the model.
But a great deal of Indian manufacturing — fabrication shops, tool rooms, job work — still runs on 2D drawings, and someone who can produce and read them properly is genuinely useful. Most mechanical engineers end up needing both, and this is the faster of the two to become employable in.
Questions
AutoCAD for Mechanical Engineering — frequently asked questions
How is this different from SolidWorks?
AutoCAD is 2D drafting; SolidWorks is 3D parametric modelling that generates drawings from a model. Most modern design offices model in 3D. But shop floors, fabrication and a great deal of Indian manufacturing still run on 2D drawings, and being able to produce and read them properly is a real skill. Many engineers need both.
Why does tolerancing get so much attention?
Because it is where drawings cost money. Tolerance everything tightly and manufacture becomes expensive and slow; tolerance loosely where it matters and the parts do not fit. Deciding which dimensions are critical is engineering judgement rather than drafting, and it is what separates a draughtsman from a designer.
First angle or third angle projection?
India and most of Europe use first angle; the United States uses third. You will meet both, and reading a drawing in the wrong convention produces a mirrored part. The course teaches both and insists on the projection symbol in every title block for exactly this reason.
Do I need mechanical engineering knowledge?
Some helps, particularly for the tolerancing module where the question is what the part has to do. Diploma and degree students take this comfortably. If you are from another background but working in manufacturing, the drawing standards modules are still entirely learnable and immediately useful.
