Design and Communication Graphics replaced Technical Drawing in the Leaving Certificate in 2009 restructuring the terminal examination and introducing a project to examine the computer skills learned by the student using Solid Works. The course is divided into the Core Elements, of which all aspects are studied, and an Optional Module, where the student studies two of the five options available.

Core Elements

The core comprises of all the key elements of Design and Communication Graphics. The core will give students a thorough understanding of the principles of plane and descriptive geometry and the communication of design and computer graphics. There is no designated order in which the elements are to be taught. An integrative approach where links are established between each of the elements of the core where possible would be most beneficial.


Plane and Descriptive Geometry

Projection Systems

Plane Geometry Conic Sections

Descriptive Geometry

Intersections and Developments of Surfaces

Communication of Design and Computer Graphics

Graphics in Design and Communications

Communication of Design

Freehand Drawing

Information and Communication technologies


Optional Modules

The options are five distinct areas of Design and Communication Graphics each with a basis in the core providing the student with the opportunity to study particular aspects of the course in more detail. Students must study two of the five options in addition to the core. The options are:


Dynamic Mechanisms

Common Geometric Loci

Construction of Loci

Construction of Tangents

Cam Profiles and Displacement Diagrams

Structural Forms

Natural and Manufactured Structural Forms

Singly and Doubly Ruled Surfaces

The Hyperbolic Paraboloid

Plane Directors

Geodesic Dome = 4 Points of Frequency

Geologic Geometry

Interpolation and Plotting of Contours

Profiles. Cutting/Embankment for level and inclined Constructions

Dip. Strike and thickness of Strata

Skew Boreholes

Surface Geometry

Dihedral angles

Surface developments/Transition Pieces

Projection/Intersection of Solids

Projection/Intersection of Ducting Details


Modelling Assemblies in 3D CAD

Layouts, Conventions and Symbols

Sectional Views

System of Projection


In Design and Communication Graphics there are two assessment components

  • A student assignment: 40% of the examination marks, of which CAD will form a significant and compulsory component.
  • A terminal examination paper: 60% of the examination marks.
