What is the difference between
Sketching & Drafting?
 Essentially the difference is that when
you are sketching, you ONLY use a
pencil and your hand.
 The minute you use a tool like a
triangle, you are drafting, because a
tool helps you draw things more
precisely.

How many views does every object
have?
 They are six (6) views we could draw,
but we only draw three (3).
 Top, Front, & Right Side.
 We will cover these more in depth later.

6
We draw oblique pictorials, of
which the front view angle is 900
and the sides are 450.
Cabinet = Full depth
Cavalier = ½ depth
 We will cover these more in depth later

7
We draw isometric pictorials in
which all of the views are drawn at
300.
 We will cover these more in depth later

8
Different lines we could draw.
 There actually many more, these are
just the basics.

Drawing
Mechanical Pencils (2)
.5mm & .7mm
Eraser
Shield
 Mechanical Pencils: for
drawing, use the .5mm for all
general work. Use the .7mm
for darker or finished work.
 .5mm is the “work horse”keep
all lines light until you are
finishing it up.
 Eraser Shield is for erasing
parts of the drawing. It will
help keep you from erasing

 Lettering Guide is used to
create guide lines for
lettering.

commonly used angles
required.
 When combined, they
can get you all of the
other angles you might
need.

Drafting Scales
 Used to draw objects precisely or
exactly.
 Engineers: deals primarily with
inches and based on 10 “parts”.
 Architectural: deals with feet &
inches.
 16 is regular ruler. All other the
fractions represent a foot or 12”.
 Metric based on MM & 10 “parts”.
 Refer to lessons on Scales for
more information.

Summary
 You need to know your tools and how to
correctly use them.
 Yes, Auto CAD is the most used tool, but
you must understand how the process
works. Then, you’ll become a better
drafter.
 Also, very often you maybe called upon to
draw something with no computer around,
so you will be better prepared if you know
these tools and how to use them.
