Orthographic Projection: Mechanical Drawing is one of 9 topics in the Grade 10 Engineering Graphics and Design CAPS syllabus, covered across 3 lessons on Study Vault. Below are real practice questions from this topic with full worked answers.
Sample practice questions
Easy
1. In third-angle orthographic projection, where is the top view drawn relative to the front view?
Above the front view
Below the front view
To the left of the front view only
There is no fixed relationship
Answer: Above the front view — In third-angle projection, the top view is drawn above the front view, since each view appears on the same side as the direction it was viewed from.
Easy
2. Which projection system is used for Grade 10 mechanical drawing content?
Third-angle projection
First-angle projection
Oblique projection
Isometric projection
Answer: Third-angle projection — Grade 10 EGD introduces third-angle orthographic projection specifically for mechanical drawing content, producing working drawings of mechanical castings.

3. Name the item, placed in or near the title block, that shows a reader which projection system (first- or third-angle) was used on a drawing.
Answer: the projection symbol — A standard projection symbol placed in or near the title block shows the reader which projection system was used; a competent reader must check this before interpreting the layout of the views.
