1. NECO Technical Drawing Exam Format <a name=”exam-format”></a>

The NECO Technical Drawing exam typically consists of:

• Objective Section: Multiple-choice questions covering drawing techniques, tools, and basic concepts.
• Theory Section: In-depth questions requiring candidates to produce detailed drawings and diagrams, often including projections, sectioning, and scale drawing.

Candidates are encouraged to study both sections thoroughly, as a strong grasp of theory is essential for successful practical application.

2. Sample NECO Technical Drawing Questions <a name=”sample-questions”></a>

Objective Questions (Sample)

1. What is the primary purpose of an orthographic projection?
   • A) To depict 3D objects in 2D views
   • B) To measure areas accurately
   • C) To create pictorial drawings
   • D) To improve perspective
2. In technical drawing, a ‘hidden line’ is represented by which type of line?
   • A) Solid line
   • B) Dashed line
   • C) Dotted line
   • D) Wavy line
3. Which of the following is not a common tool in technical drawing?
   • A) T-square
   • B) Compass
   • C) Protractor
   • D) Stethoscope

Theory Questions (Sample)

1. Draw the front, top, and side views of a hexagonal prism with a base edge of 3 cm and height of 5 cm.
2. Given a mechanical part with various holes and projections, create a detailed sectional view showing the internal features accurately.
3. Explain the process of dimensioning in technical drawing, including at least three dimensioning rules.
4. Illustrate and label a simple bearing assembly using proper sectional views and indicate all necessary tolerances.

3. Answers & Solutions <a name=”answers-solutions”></a>

Objective Section Answers

1. Answer: A) To depict 3D objects in 2D views.
2. Answer: B) Dashed line.
3. Answer: D) Stethoscope.

Theory Section Solutions

• Question 1 Solution: For the hexagonal prism, use a standard drawing sheet to show three views. Ensure all edges are aligned, and label the views (front, top, and side). Use correct dimensions: base edge of 3 cm and height of 5 cm.
• Question 2 Solution: Begin with a complete projection of the mechanical part, sectioning along the specified plane. Use hatching for solid areas, and show the interior holes and cavities precisely.
• Question 3 Solution: Dimensioning involves placing measurements on drawings to indicate the sizes and positions of features. Rules:
  1. Dimensions should be placed outside the object views.
  2. Extension lines should not touch the object.
  3. Avoid over-dimensioning; only essential dimensions should be included.
• Question 4 Solution: Draw the bearing assembly with a section cut to reveal the internal structure. Indicate dimensions for tolerances, such as hole diameters and shaft thickness, and use hatching for cross-sectional areas.

4. Study Tips for NECO Technical Drawing <a name=”study-tips”></a>

1. Practice Past Papers: Review previous years’ NECO Technical Drawing exams to understand the question format and common themes.
2. Master Drawing Tools: Get comfortable using T-squares, compasses, protractors, and drawing sheets for accurate work.
3. Understand Projections: Study different types of projections (orthographic, isometric) and when each is used.
4. Review Basic Geometry: Shapes like prisms, cylinders, and pyramids are frequently asked in NECO Technical Drawing exams.
5. Time Management: Allocate time wisely during the exam to complete both objective and theory sections thoroughly.

FAQs

1. Can I use a calculator for NECO Technical Drawing?

• Yes, a basic calculator is allowed for solving measurements, but it’s best to practice mental calculations for faster drawing dimension adjustments.

2. How are sectional views marked in technical drawing?

• Sectional views are marked by using section lines (hatching) across cut areas, with a label indicating the section plane (e.g., “Section A-A”).
