Design and Communication Graphics

Design and Communication Graphics (DCG) has taken the place of technical drawing for the Leaving Certificate and provides students with the opportunity for visualizing and comprehending information presented verbally or graphically.

Problem solving and creative thinking skills are developed through the analysis and solution of both 2- and 3-dimensional graphics. Graphics and design are communicated using freehand sketching skills, traditional draughting equipment and CAD.

If you are interested in taking this subject to Leaving Certificate level you will have taken Tech Graphics to Junior Certificate level. 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. 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. This course now has a project aspect.

Career Possibilities

DCG is a core element of many 3rd level options including Engineering, Construction and Architecture and knowledge of this subject will greatly enhance a student’s ability in any 3rd level engineering based programme. All apprenticeships include the study of detailed technical drawings.

Third Level Entry Requirements

This subject is not an essential requirement for any courses in the CAO system.

Subject Content

Consists of a core section comprised of (a) plane and solid geometry and (b) communication computer graphics. There is also an options section of applied graphics, two options are to be taken.

It is an advantage to have studied Technical Graphics at Junior Cert. level.
Free-hand sketching is a main component of the core therefore Junior Cert art, materials technology wood and/or technology would serve as an advantage in this area.

A basic knowledge of ICT skills is also beneficial.

Students must also appreciate that work completed must conform to a high standard of neatness and draftsman-ship.
