Design & Communication Graphics  -  Leaving Cert only.

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 & Descriptive Geometry 

• Projection Systems 
• Plane Geometry Conic Sections 
• Descriptive Geometry 
• Intersections & Developments of Surfaces 

Communication of Design & Computer Graphics 

• Graphics in Design & Communications 
• Communication of Design 
• Freehand Drawing 
• Information & 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.

Dynamic Mechanisms    

• Common Geometric Loci 
• Construction of Loci 
• Construction of Tangents 
• Cam Profiles & Displacement Diagrams    

Structural Forms 

• Natural & Manufactured Structural Forms 
• Singly & 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 


• Modeling Assemblies in 3D CAD 
• Layouts, Conventions and Symbols 
• Sectional Views 
• System Of Projection 


The examination is offered at two levels – Ordinary and Higher. At each level there are two examination components:

• 1. Practical coursework (Student Assignment) (40%)
• 2. A final examination in graphics (60%)
