Summary

• Description:

  The MS Word document comprises CEKENAS Drawing and Design Paper 1 2026 Pre-Mock Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  It was a CEKENAS Form 4 Drawing and Design Paper 1 theory and technical drawing examination testing plane and solid geometry, engineering standards, loci, and assembly drawing. Designed to prepare students for the KCSE engineering drawing exam, available for PDF download with complete marking scheme support.

  • Duration: 2 ½ Hours
  • Total Marks: 100 Marks
  • Number of Questions: 14 (Questions 1–14)
  • Structure: Section A (50 marks, compulsory short questions 1–10), Section B (20 marks, compulsory assembly drawing Question 11), and Section C (30 marks, choice of two questions from 12–14 [15 marks each]).

  It covers the following topics:

  • Section A

    • Architectural and electrical symbols identification
    • Geometrical construction (Polygon construction from perimeter ratio and angle parameters)
    • Orthographic projection of tilted solids (Plan and elevations of tilted hexagonal pyramid)
    • Area conversion geometry (Converting a regular pentagon into an equivalent area triangle)
    • Tangency (Constructing external tangents to two non-equal circles)
    • Diagonal scale construction and distance measurement
    • Solid geometry (Completing plan and true shape of cut face for a truncated square pyramid)
    • Isometric projection sketching from orthographic views
    • Third angle orthographic projection sketching from isometric views
