PROJECTION
• Referring to duty a master to record size
measure and form of object three dimensional
surface of drawing paper sheet, hence needed
the way of / system which must follow, so that
sketch / yielded picture easily can understand.
• For all technique picture way of / the system
developed same base that is picture by /
projection system.

Projection Dot
•
•
This dot projection to represent base of
congeniality of perspective where all lines meeting
each other a dot.
With this congeniality hence object / area /
projected line will yield picture which vary the level
of cause very depended where projection area /
picture put down.
6
7
• Dot projection / in perspective imprecise /
useless as picture reference work because
of in perspective cutting not lay open form
goodness which by exact.
• Usefulness foreshorten this at one
particular certain storey;level weared by
master in preparation of just antecedent
sketch.
8
•
Parallel Projection.
Same its congeniality with
dot projection / in
perspective, the difference
dot meeting of line reside
in [at] place which is not
limited (far), so that
projection lines ( projector)
of meeting dot become
parallels is ? named
parallel projection.
9
Oblique Projection.
• In this oblique projection, cutting yielded by wearing
projection lines ( projector ) parallel which form other
angle;corner from 90 degree of with projection area.
• Generally one face placed parallel with projection
area and projection line taken 45 degree.
• This will give visible cutting painting hereunder, this
visible cause show next face and one or more than
one additional face for object.
10
• In picture showed oblique projection a cube. If
angle/corner level of 45 degree, yielded to be picture to
be referred projection of cavalier ( Projection Cavalier )
or in general recognized by the name of “ oblique
11
Projection of
Orthographic.
• Named projection of
orthographic because
parallel projection lines
altogether vertical and
picture area.
12
Plural cutting projection.
• When one of surface of parallel object with
picture area, hence yielded picture in form of like
surface of object, this projection represent
projection of orthographic recognized by the
name of plural cutting.
• Because yielded picture not lay open thickly [of]
object, hence needed one or more than one
additional projection to equipping.
13
• Two projection usually
have last for
elaborating simple
object, but for very
needed complicated
object of addition
again three, four or
more.

PROJECTION of AXONOMETRIC.
• If object turned around and lifted that way aspect
so that third oblique surface to projection area,
hence yielded picture represent projection type
of orthographic special known as projection of
axonometric.
16
• Because object can be put down in
dimiciling untold to the number of relative
to projection area, hence unnumbered
cutting can be made, to different each
other in comparison generally, its flank
length and also in its angle;corner size
measure.
17
Because of is practical, some from
possibility domicile this have been
classified by so aspect, so that give the
division of projection of axonometric which
have been recognized, that is:
• Isometric projection
• Metric projection
• Trimetric projection

Metric projection
• Metric projection represent modified
isometric projection form, where high size
measure, wide and in altered to give
impression of reality. Metric mean two size
measure.
