Ethiopian Old Curriculum Grade 12 Technical Drawing (TD) has 5 units. They are:

1. Sketching and Visualization
2. Auxiliary Views
3. Sectional Views
4. Dimensioning
5. Development and Intersection

Unit 1: Sketching and Visualization (5 periods)

Trains teachers to help students practice free-hand sketching, understand its role in the design process, and appreciate sketching as a tool for developing and communicating ideas.

Unit 2: Auxiliary Views (13 periods)

Provides teaching strategies for orthographic projection and auxiliary views, enabling students to represent the true shape of inclined surfaces in technical drawings.

Unit 3: Sectional Views (12 periods)

Guides teachers on explaining the purpose and types of sectional views, and how they reveal internal features of objects for accurate description.

Unit 4: Dimensioning (7 periods)

Equips teachers to teach dimensioning principles, conventions, and standards, helping students describe object sizes correctly in technical drawings.

Unit 5: Development and Intersection (21 periods)

Covers surface development and intersections, enabling teachers to train students in forming 3D models, joints, and sheet-metal applications using technical drawing methods.
