SCHEME OF EXAMINATION
The Technical Drawing examination will comprise three papers, namely Papers 1, 2, and 3, all of which must be attempted. Papers 1 and 2 will be combined into a single composite paper to be completed in one sitting.
PAPER 1
This paper will consist of forty multiple-choice objective questions, to be answered within 1 hour, carrying a total of 40 marks. It will consist of two sections, namely Sections A and B.
Section A
This section will encompass thirty questions focused on the general principles, techniques, and applications of plane and solid geometry.
Section B
Within this section, there will be ten questions divided into two alternative parts: Part I (Building Drawing) and Part II (Mechanical Drawing). Candidates are required to choose and respond to questions from only one part.
PAPER 2
This paper will consist of five essay questions related to plane, solid, and vector geometry. Candidates will need to answer any three of the questions within 1¾ hours, and this section carries a total of 60 marks.
PAPER 3
This paper will be divided into two sections, Sections A and B, to be completed within 2¾ hours and carrying a total of 100 marks.
Section A
In this section, candidates will be presented with three questions that require sketches of objects, components, symbols, and tools commonly used in the Building and Mechanical industries. One of the questions will be compulsory and carry 20 marks, while candidates must choose and answer one additional question for 10 marks. This section will have a time allocation of 45 minutes.
Section B
This section will consist of two questions, one focused on Building Drawing and the other on Mechanical Drawing. Candidates are required to select and answer only one of these questions within 2 hours, with the section carrying a total of 70 marks.
What are the Topics under Technical Drawing?
Geometrical Constructions
This topic focuses on basic constructions using a compass, ruler, and other drawing tools. It includes constructing angles, perpendicular lines, parallel lines, bisecting lines and angles, and dividing lines into equal parts.
Orthographic Projection
Orthographic projection involves representing three-dimensional objects on a two-dimensional plane. This topic covers different views of an object, such as the front view, top view, and side view, and how to draw them accurately.
Isometric and Perspective Drawing
Isometric drawing involves representing three-dimensional objects in a simplified, 3D form using a set of guidelines. Perspective drawing, on the other hand, creates a sense of depth and realism by drawing objects as they appear in a specific viewpoint or vanishing point.
Dimensioning
Dimensioning involves adding measurements and annotations to technical drawings to indicate the size and location of different features accurately. This topic covers various dimensioning techniques, including linear dimensions, angular dimensions, and tolerances.
Sections and Development
Sections involve representing the internal structure of an object by cutting it open and showing the hidden details. Development refers to the process of unfolding or unrolling surfaces to create flat patterns, such as in sheet metal fabrication.
Auxiliary Views
Auxiliary views are additional views used to show the true shape and size of an inclined or oblique surface. This topic covers the construction of auxiliary views to provide a more accurate representation of complex objects.
Assembly and Exploded Views
Assembly views show how multiple components fit together to form a complete object. Exploded views demonstrate the individual components of an assembly, providing a clear understanding of their arrangement.
WAEC Technical Drawing Questions and Answers 2023 - FAQs
