  2. Technical GraphicsCommunicates Information Technical Graphics is a Universal Language

  3. What is Technical Graphics • Technical Graphics is one of the technology subjects offered at junior cycle. • In Technical Graphics students use drawing equipment to create precise and accurate drawings. • These drawings are used to communicateideas or solve problems.

  4. What will I learn in Technical Graphics? • How to produce neat drawings of everyday items • How to represent 3-D objects on paper • How to create models of objects on the computer • How to use freehand sketching, colouring and shading to represent objects

  5. Skills developed in Technical Graphics • Communication skills • Problem solving skills • Computer skills • Creative thinking skills
