सवाल

Which syllabus does this course follow?

The NCVT / DGT CTS (NSQF) Draughtsman Civil Trade Theory syllabus for Year 1. The centre follows the student's own ITI syllabus where it differs.

Is surveying taught with instruments?

Theory classes explain chain, compass, level and plane table; field work is done in the matching Trade Practical course.

Will AutoCAD be taught?

Year 1 focuses on manual drafting; CAD drafting is part of Year 2 and is also available as a separate course.

Is maths needed?

Basic arithmetic, mensuration and trigonometry are used for scales, surveying and stair calculations.
