Design and Communication Graphics
What is the subject about?
DCG is an exciting and dynamic subject which covers a broad variety of topics including Projection Systems, Pictorial Projection, Dynamic Mechanisms and Structural Forms. Problem solving and creative thinking skills are developed through the analysis and solution of both 2-dimensional and 3-dimensional graphics. DCG also includes a Computer Aided Design (CAD) element. This involves the use of computer software (SolidWorks) to virtually model products and artefacts. Graphics and design are communicated using freehand sketching skills, traditional draughting equipment and Computer Aided Design. There is a great emphasis in the Leaving Certificate course on comprehension, analysis and problem solving. In simple terms you must be able to understand what has to be done, analyse how you are going to approach it and then proceed to solve the problem.
How is the subject assessed?
The leaving certificate course comprises of two components at Higher and Ordinary Level
I. Student Assignment (40%)
The assignment is completed between September and January of 6th year. Students are given a prescribed design brief which requires them to:
– A: create a Model an existing product using SolidWorks
– B: modify the existing design or develop a completely new design concept for the product they designed in Part A
The assignment is presented in a portfolio which will consist of research evidence, initial design ideas/sketches, working drawings and 3D drawings created using SolidWorks.
The design brief changes every year:
– Gaming Headset
– Mobile Phone
– Computer Mouse
– Reusable Water Bottle
II. Drawing Examination (60%)
The course is comprised of two parts; Core areas of study and Optional Areas of Study
Section A and Section B – Core Areas of Study
– Plane and Descriptive Geometry
– Projection Systems
– Plane Geometry
– Conic Sections
– Descriptive Geometry of Lines and Planes
– Intersection and Development of Surfaces
Section C – Optional Areas of Study (You will be required to study two of the optional areas listed below)
– Applied Graphics
– Dynamic Mechanism
– Structural Forms
– Geological Geometry
– Surface Geometry
– If you are interested in taking this subject to Leaving Certificate level, it is a requirement to have taken Technical Graphics to Junior Cycle level
– If you have studied any of the following subjects at Junior Cert Level it will greatly help: Technical Graphics, Materials Technology Wood, Art and Maths
– Leaving Certificate subjects that compliment DCG: Construction Studies, Art, Applied Mathematics and Physics.
– Although it is not an essential subject for either architecture or engineering, it is regarded as a useful asset if you are thinking of a technical course.
