4. DRAWING
- is an art of representing
objects or ideas on a plain
surface (such as sheet of
paper) by means of lines,
marks or symbols

5. IMPORTANCE OF DRAWING
1.
2.
3.
Drawing is a valuable means of
expression to everyone.
Drawing is an effective aid to
verbal language.
Drawing helps to get idea
across when words fail.

6. Two Types of Drawing
1.
2.
Free-hand Drawing- drawing
made without the aid of
drawing instrument.
Mechanical Drawing-drawing
m a d e u s i n g d r a w i n g
instruments (triangles, ruler,
compass, t-squre, etc.)

7. 3 DRAFTSMAN TOOLS
1. Pencil
2. Paper
3. Eraser

8. PENCIL
- is a slender, rod shape drawing
instrument made of wood or any
other composition with a center
stick of graphite (kaolin clay)
added in varying amounts to make
18 grades from 9H (the hardest) &
7B (the softest)

9. PENCIL GRADES
1)
-
Hard Pencil (9H, 8H, 7H, 6H, 5H, 4H)
Used in drawings requiring a high degree
of accuracy such as charts, diagrams, &
graphical computations.
2) Medium Pencil (3H, 2H, H, F, HB, B)
- Used for drawing straight line works &
other freehand drawings.

10. PENCIL GRADES
3) Soft Pencil (2B, 3B, 4B, 5B, 6B, 7B)
- Used for rendering or in artworks of
various kinds.

11. PENCIL POINTS
1)
-
Conical Point
Used for general purposes. Pencil
is sharpened in the shape of a
cone.

12. PENCIL POINTS
2) Chisel or Wedge Point
- Used for drawing thick lines. Both
end or sides of the lead is sharpened
into the shape of chisel.

13. PENCIL POINTS
3) Elliptical Point
- Used for compass works. One side
of the lead is cut or sharpened.

14. USES OF PENCIL
1)
2)
3)
For marking
For drawing or sketching
For lettering

15. How to sharpen a
pencil?

16. What is a line?
Line is a path of moving
a point.

17. Two types of line?
1) Straight Line –
is the shortest distance
between two points.
2) Curve Line-line of which no
point is straight

18. Kinds of straight line:
1) Horizontal Line –
line drawn from left to right.
2) Vertical Line-
line drawn from top to bottom (if
drawn mechanically, from bottom to
top)

19. Kinds of straight line:
3) Inclined Line (slanting
line/diagonal line)-
l i n e w h i c h i s n e i t h e r
horizontal nor vertical.

20. Other Kinds of straight line:
4. Parallel Lines –
lines lying on the same plane
& are equally distant to one
another.
5) Intersecting Lines-
lines that cut across each
other.

21. Other Kinds of straight line:
6) Perpendicular Lines-
lines forming two right
angles (90°)
