सवाल
Which syllabus does this course follow?
The NCVT / DGT CTS (NSQF) Draughtsman Mechanical Trade Theory syllabus for Year 2. The centre follows the student's own ITI syllabus where it differs.
Is 3D modelling included?
Yes, the CAD unit covers basic 3D solid modelling and getting 2D views from the model.
Which CAD software is used?
AutoCAD is used for teaching; the same ideas apply to other CAD packages.
Will this help in getting a job?
Yes, reading and preparing detail and assembly drawings is the main daily work of a mechanical draughtsman.
