Questions
Which syllabus does this Machine Drawing with CAD course follow?
It follows the BTEUP diploma syllabus (Mechanical Engineering - Semester 3). If your polytechnic or university syllabus differs, the centre follows your own syllabus and unit order.
Will this help in the semester exam?
Yes. Each unit is taught with board-pattern questions, numericals where needed, and revision tests before the end-semester exam.
How is the practical work assessed?
The trainer watches each experiment / milestone and marks it on a rubric, followed by viva questions, as in the board practical exam.
Which CAD software is used?
AutoCAD is used in the lab; the same drawings can also be made in any CAD software your polytechnic uses.
