About

You will be able to

  • Explain NCVT CTS Draughtsman Mechanical trade theory: drawing standards, projection, sections and machine drawing
  • Draw orthographic, sectional, isometric views and developments of surfaces accurately
  • Draw fasteners, machine components, assembly and detail drawings with a bill of materials
  • Apply limits, fits, tolerances, surface finish and welding symbols on drawings
  • Draft 2D drawings and simple 3D models in CAD
  • Answer workshop calculation, science and employability skills questions with confidence

Who it is for

  • ITI Draughtsman Mechanical trainees (1st and 2nd year) wanting extra theory and drawing practice
  • Students preparing for ITI internal tests and the CTS examination
  • Pass-outs revising for mechanical draughtsman, CAD operator or apprenticeship jobs

What you need

  • Admission in (or completion of) the ITI Draughtsman Mechanical trade, normally 10th pass
  • Drawing instruments; the centre provides a CAD lab

Questions

Is sheet practice included?

Yes. Every chapter has drawing sheets that the trainer checks for projection, lines, dimensions and neatness.

Will I learn CAD?

Yes. 2D drafting and an introduction to 3D modelling are covered in the CAD lab.

Is it for 1st or 2nd year?

Both. It follows the NCVT CTS Draughtsman Mechanical curriculum; batches are formed year-wise.

Are tests included?

Yes, chapter-wise MCQ tests and full CBT-style mock tests.
