1 Terms & Definitions Drafting & Design Technology Unit 2

2 Drawing media Any type of drawing material upon which an object is graphically represented

3 Horizontal Parallel to the plane of the horizon

4 Lead Made of graphite with kaolin (clay) added in varying amounts in order to make the eighteen grades from the hardest to (9H) to the softest (7B)

5 Parallel Two lines or surfaces side by side, equal distance apart at all points

6 Perpendicular At a 90  angle to a given plane or line

7 Vertical A line straight up and down, perpendicular to the horizontal plane

8 Working Surface Any surface such as a drafting board or desk used to secure drawing media
