KEY WORD: SKETCH, LAYOUT, CAD, DRAWING, SCALE, HEIGHT-WIDHT-DEPTH.
BOOK: UNIT 3. "COMPARISON".
- Dimensions: Height, Width, Lendth.
- Comparative forms: -er/..more than.
- Superlative form: -est/ the most.
1º INTRODUCTION:
a) We use it to measure angles:Protactor
b) We use it to draw parallel and perpendicular lines:set square
c) We use it to draw arcs and circumferences:compass
d) We use it to measure the length of lines:ruler
2º METHODS:
Technical drawing can be made using three different methods: - Dimensions: Height, Width, Lendth.
- Comparative forms: -er/..more than.
- Superlative form: -est/ the most.

1º INTRODUCTION:
Design ideas can be communicated in many different ways.The most common method of communicating ideas is through drawings and sketches. These can be used to communicate to clients, end users, manufacturers and other designers or experts, to name a few.Designers use also very often sketches to communicate to themselves.
Sketching ideas on paper helps them to visualize products more fully and examine problem areas better. It also frees up their minds, allowing them to develop new ideas: EG. PREHISTORIC CAVE PAINTING, RENAISSANCE PERSPECTIVE, ABSTRACT PAINTING, PERSPECTIVE DRAWING, 3D DRAWINGS, DIGITAL ALTERARED PHOTOGRAPH.

ACTIVITIES Nº2.
2.1. Using the computer, draw the following arches using AutoCAD.(open here)2º METHODS:
- a) SKETCH: It´s a freehand drawing where you put your ideas on a paper quickly and maintains its proportions and incorporates its dimensions. In this case we don´t have to use rulers, only with a pencil.
- b) TECHNICAL DRAWING (LAYOUT): It´s a drawing where you have been using rules, set square, compass (instruments) to give an exact picture. In this case if we use a computer to drawing, then this method is called GRAPHICS (CAD=Computer Addes Desing). Here are several types of these methods:
