सवाल
Which syllabus does this course follow?
The NCVT / DGT CTS (NSQF) Draughtsman Mechanical Trade Theory syllabus for Year 1. The centre follows the student's own ITI syllabus where it differs.
Is CAD covered in Year 1?
Year 1 theory focuses on manual drafting principles; CAD practice starts in the practical course and continues in Year 2.
Why are workshop processes taught to draughtsmen?
A draughtsman must know how parts are made so that drawings are practical to manufacture.
How is the course assessed?
By chapter tests with multiple-choice questions like the AITT pattern and regular sheet work.
