Question 1

what is freehand sketching

Answer 1

Is used to transfer the idea of an engineer’s abstract world to the

real world in 2D and 3D.
- It is used for daily communication in the engineering world as
drawing is the international language of engineering.
- is such a drawing which is drawn without measuring instruments.

Question 2

enumerate the freehand sketching tools

Answer 2

pencil
eraser
paper

Question 3

comes in many different hardnesses; the harder the lead, the lighter and crisper the line.

Answer 3

pencils

Question 4

used to correct mistakes in a line, not to make changes in a design.

Answer 4

Eraser

Question 5

enumerate the four mature grips

Answer 5

Lateral Tripod
Dynamic tripod
Lateral Quadrupod
Dynamic Quadrupod

Question 6

the thumb and forefinger act like pincers, gripping the barrel of the pencil near its tip.

Answer 6

dynamic tripod

Question 7

the thumb and the first three fingers are used to grip the
pencil. Only the pinky finger and the outside portion of the hand provide stability. The
thumb doesn’t cross over. It assists the other three fingers in directing the pencil.

Answer 7

dynamic Quadrupod

Question 8

the thumb wraps across the
barrel of the pencil, and the pencil rests on the top of the
ring finger. The fingers work together to direct the pencil,
and the thumb acts primarily to hold the pencil in place against the
forefinger.

Answer 8

lateral quadrupod

Question 9

The second most common grip pattern involves the
thumb and first two fingers, like the dynamic tripod. The
difference is that the thumb crosses the barrel of the pencil,
clamping it to the forefinger.

Answer 9

lateral tripod

Question 10

most important part of free hand drawing as sketching

Answer 10

line

Question 11

4 types of line

Answer 11

vertical
horizontal
oblique
circle

Question 12

a common shape in technical drawings.

Answer 12

Rectangles

Question 13

is the process of creating illustrations with letters, numbers, or any type of character or phrase.

Answer 13

lettering

Question 14

was the hand used in the Middle Ages by the
church, at the time the undisputed center of learning and scholarship.

Answer 14

Blackletter (old english)

Question 15

known as Round Hand, or Spencerian Script, was perfected by European penmen and engravers during the 17th and 18th centuries. It is slanted at 55° to the base, it may vary but not less than 50°.

does not follow the fundamental rules of
traditional calligraphy scripts such as Copperplate, Spencerian, Italic, Blackletter, etc.

Answer 17

Modern calligraphy

Question 18

enumerate the 7 shading techniques

Answer 18

Hatching/Parallel Hatching
Cross Hatching
Scribbling/Doodle
Stippling
Tick Hatching
Woven Hatching
Contour Hatching

Question 19

This can be considered the most basic of all of the shading techniques included
here. It involves creating groups or patterns of parallel lines.

Answer 19

Hatching/Parallel Hatching

Question 20

is like taking parallel hatching to the next level. You create a first layer of parallel lines (in
any direction) and a second layer of lines is drawn on top in a perpendicular or nearly perpendicular manner.

Answer 20

Cross Hatching

Question 21

an excellent technique to use when drawing specific subjects like trees or hair because it is
not only creates values, but also transmits a sense of texture.

Answer 21

Scribbling/Doodle

Question 22

tone and texture is built up by applying dots in different densities. This technique takes time and you have to make sure that you don’t start creating lines instead of dots.

Answer 22

Stippling

Question 23

This method is similar to stippling but instead of making
dots, you make short lines. In darker areas, lines are
placed in an overlapped manner.

Answer 23

Tick Hatching

Question 24

leads to a very interesting outcome when done correctly. This technique involves creating sets of short(er) parallel lines in one direction and then placing another group of parallel lines next to it in perpendicular or near-perpendicular directions.

Answer 24

Woven Hatching

Question 25

This technique involves using lines that follow the curves or lines of the initial contour/outline drawing.

Answer 25

Contour Hatching

Question 26

enumerate the essential steps to achieving successful shading

Answer 26

1. Make sure you select a good photographic reference
2. Create a light pencil sketch including only outlines of shapes
3. Take a moment to observe the reference picture and answer the following questions:
4. Start developing those values!
5. Consistency is key
