ICSE Class 10 Technical Drawing Applications Syllabus 2026-27
ICSE Class 10 Syllabus |
ICSE Class 10 Technical Drawing Applications is one of the most instrument heavy subjects on the board, built entirely around precise geometrical construction rather than free drawing. The theory paper runs for a full 3 hours, longer than most other ICSE papers, and covers everything from basic plane geometry to orthographic projection, isometric drawing and sectional views. This guide breaks the full syllabus down for the current session, unit by unit, along with the internal assessment requirements, marking rubric and preparation tips.
The page is reviewed regularly against the official CISCE curriculum, so it can be used as a dependable single reference while planning practice sheets and drawing files.
Quick Overview: Exam Structure
The examination carries a total of 200 marks, split evenly between theory and internal assessment. Note that the theory paper here runs 3 hours, not the 2 hours common to many other ICSE subjects.
Component | Marks |
Theory (written paper, 3 hours) | 100 |
Internal Assessment | 100 |
Total | 200 |
Part 1: Theory Syllabus (100 Marks)
The theory paper is split into Section A, covering the geometric fundamentals, and Section B, covering sections, isometric drawing and orthographic projection, across ten units in total.
Section A
● Unit 1, Geometrical Constructions: the single largest unit, covering dividing lines and circles, polygon construction for 3 to 8 sided shapes, inscribed and circumscribed circles, tangent circles and lines, and direct or transverse common tangents between circles.
● Unit 2, Area Constructions: converting polygons into triangles or squares of equal, half or double area, and combining two or three triangles into a single equivalent triangle, all based on core area theorems.
● Unit 3, Templates: constructing arcs of a given radius that touch lines, other arcs, or pass through given points, applied to real template shapes.
● Unit 4, Scales: finding the Representative Fraction (R.F.), and constructing plain scales (reading two units) and diagonal scales (reading three units) for use in field drawings.
● Unit 5, Engineering Curves: constructing an ellipse by the arcs of circles, concentric circles, or oblong method, and a parabola by the rectangle or tangent method, as used in arches, dams and manhole covers.
● Unit 6, Solids: orthographic projections of prisms, pyramids, cylinders and cones in different axis orientations, development of their surfaces, and finding the true length of an inclined edge.
● Unit 7, Oblique Drawing: converting orthographic views into oblique views, with circular parts excluded from the top view.
Section B
● Unit 8, Sections of Right Solids: sectional views of cut prisms, pyramids, cylinders and cones, development of their lateral surfaces after cutting, pipe joints such as elbow joints, and finding the true shape of a section.
● Unit 9, Isometric Drawing: converting orthographic views into isometric drawings, at full scale or at 2:1 or 1:2 only, using an isometric scale where required.
● Unit 10, Sectional Orthographic Views: converting pictorial or orthographic views into full or half sectional views under both First Angle and Third Angle projection methods.
Part 2: Internal Assessment (100 Marks)
The internal assessment has three distinct components, a drawing file, and two physical models.
● A file of at least 15 drawing assignments, covering every unit of the Class 10 syllabus, with one or two assignments per unit, prepared on half imperial size drawing paper.
● A three dimensional model made from stiff cartridge paper or chart paper, applying the development of a solid such as a prism or pyramid.
● A thermocol model showing the true shape of the section of a truncated solid, such as a prism, pyramid, cylinder or cone.
Marking and evaluation
Assignments are assessed independently by the subject teacher and an external examiner, each contributing 50 marks, against five criteria, Preparation, Analysis, Process, Results and Presentation, each scored up to 4 marks at the top grade.
Evaluator | Marks |
Subject Teacher (Internal Examiner) | 50 |
External Examiner | 50 |
Total | 100 |
How to Prepare for ICSE Class 10 Technical Drawing Applications
● Never erase construction arcs and lines, since they form part of the answer and their absence can cost marks even if the final shape is correct.
● For geometrical constructions, practise all the polygon and tangent methods repeatedly, since this is the largest unit and appears in almost every paper.
● For scales, remember that R.F. is expressed as a fraction with no units, a plain scale reads two measurements, and a diagonal scale reads three.
● For solids, keep parallel development for prisms and cylinders separate in your mind from radial development for pyramids and cones.
● For sections, remember that word problems are excluded here, the cutting plane must always be shown as a V.T. or H.T. in the figure itself.
● For isometric drawing, plot non-isometric lines point by point rather than drawing them directly, and use the four centre method for circles that appear as ellipses.
● For First Angle versus Third Angle projection, memorise exactly where the top view and side view sit relative to the front view in each system, since this is a common point of confusion.
● For the internal assessment file, use correct line types throughout, thick continuous for visible lines, thin continuous for dimensions, dashed for hidden lines, and chain line for centre lines, with a title block on every sheet.

Frequently Asked Questions
How long is the theory paper and how many marks is it?
3 hours for 100 marks, longer than the 2 hour papers common to many other ICSE subjects.
How many marks does the Internal Assessment carry, and how is it split?
100 marks, split equally between the subject teacher (50 marks) and an external examiner (50 marks).
What are the three components of the Internal Assessment?
A file of at least 15 drawing assignments, a 3D model made from stiff cartridge or chart paper showing development of a solid, and a thermocol model showing the true shape of a section of a truncated solid.
What is a Representative Fraction, or R.F.?
R.F. is the ratio of drawing length to actual length, expressed as a fraction with no units. For example, an R.F. of 1 over 50 means the drawing is fifty times smaller than the real object.
What is the difference between a plain scale and a diagonal scale?
A plain scale reads two units of measurement, such as metres and decimetres. A diagonal scale reads three units, such as metres, decimetres and centimetres, using the principle of similar triangles.
What is the difference between parallel and radial development?
Parallel development is used for prisms and cylinders. Radial development is used for pyramids and cones, unfolding the lateral surface with lines radiating from the apex.
Are word problems included in the Sections of Solids unit?
No. The syllabus explicitly excludes word problems for sectional views, the cutting plane must be shown directly in the figure as a V.T. or H.T.
What scale can be used for isometric drawing?
Full scale, or a scale of 2 to 1 or 1 to 2 only.
What is the difference between First Angle and Third Angle projection?
In First Angle (British) projection, the top view sits below the front view. In Third Angle (American) projection, the top view sits above the front view, with the side views similarly reversed.
