  1. Graphic Expression and Communication Unit 7 Technologies 1st ESO – IES Poeta Julián Andúgar Antonio Ruiz Hernández

  2. Graphic Expression • We have to distinguish between: • Artistic drawing • No rules • Express feelings and emotions • Technical drawing • International standards (rules) • Transmit ideas – Represent objects

  3. Graphic Expression • Aims of graphic expression in Technology: • To design objects or organise ideas • To show our ideas to other people • To make our designs attractive

  4. Graphic Materials • Pencil. They have a wooden case with a lead inside made of graphite and clay. +

  5. Graphic Materials: Pencil • There are two types of pencil: H and B. • Hard pencils (H) • Thin lines • Technical drawing • Soft pencils (B) • Thick lines • Artistic drawing Intermediate

  6. Graphic Materials: Paper • Paper can be classified by size, weight and finish. • Depending on the size we distinguish different formats: • Starting with DIN-A0 (Deustche Industrienorm): 118.9 cm A1 A3 A5 A4 84.1 cm A2

  7. Graphic Materials: Paper • Depending on the weight the paper is thicker or thinner. • Depending on the finish we distinguish: • Rough paper • Smooth paper • Shiny paper

  8. Drawing tools • Ruler. We use it to measure the length of a segment. • Protractor. We use it to measure and draw angles.

  9. Drawing tools • Set square. For drawing parallel and perpendicular lines. They come in two shapes: • Right-angled isosceles triangle. • Right-angled scalene triangle

  10. Drawing tools • Compasses. Two connected arms, one with a sharp metal point and the other with a lead. It is used to draw circles and arcs.

  11. Sketch, Diagram and Technical Drawing • Sketch. Freehand. Shows first idea of the object. • Diagram. Freehand. Gives more specific information: measurements, materials,… • Technical drawing: Same information as a diagram, but using drawing tools (ruler, set squares, compasses,… or a computer) Sketch Diagram Technical Drawing

  12. Scales • Definition. We use the scales to fit the objects on the drawing surface (paper). • There are 3 types of scales: • Full Scale. We draw the life-size object. (S = 1:1). • Scale to reduce. To draw objects bigger than the paper. (S = 1:X). Examples: S=1:2, S=1:10… • Scale to enlarge. (S = X:1). Examples: S=2:1, S=5:1,…

  13. Dimensions • Definition. We use dimensions to indicate the measurements of an object. • Dimension rules • 1st. Normally dimensions are expressed in milimeters. If not, we have to indicate the units. • 2nd. Don’t duplicate the information (only draw the necessary dimensions). • 3rd. Draw the dimension centered above the dimension line. If it is vertical, draw it on the left. • 4th. Don’t use parts of the piece as auxiliary dimension lines. • 5th. If possible, no line should cross any dimension line
