Mechanical Drafting Syllabus — Unit-wise Content
The official GTU curriculum for Mechanical Drafting (subject code 4321902) as prescribed for MECHANICAL · Semester 2 divides the course into 6 units, covering 30 listed topics. The unit-wise breakdown below is read from the GTU syllabus document for this subject code, so you can check what the course actually covers before deciding which papers to attempt.
Download the official syllabus PDF (4321902)Unit 1 Multiviews with sectional orthographic representation
- 1.1. First & third angle projection methods & and positions of six views.Importance of it in engineering drawing field.
- 1.2. Multi view drawings (all six views) from given isometric drawing / pictorial view.
- 1.3. Need of sections, section lines &cutting plane, rules forsectioning and section lines.
- 1.4. Types and application of sections- full, half, revolved, removed, partial, off-set, aligned, etc.
- 1.5. Sectional view drawings from given isometrics drawing / physical object and cutting plane conditions.
- 1.6. Missing view drawings from given adequate orthographic views. (Facultyshoulddemonstratethe physical model/dirty model/3D CAD model for better conceptualization and in depth understanding of topic.)
Unit 2 Intersection and Penetration of Solids and Surfaces
- 2.1. Types and dimensional specifications ofsolids (prism, pyramid, cylinder, cone).
