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.

- With a set square, we can...draw parallel lines
- With a protactor, we can...measure angle
- With an oblique system, we can...represent together of the viewa o an object
- With the conical system, we can...represent an object like we see it
(...measure angles. /...represent together of the views of an object. /...draw arcs./...draw parallel lines. / represent an object like we see it.)
