2. WHAT ARE
STRUCTURAL
ENGINEERING
DRAWINGS?

3. Introduction
A type of technical drawing that
shows details and information
such as…
RoofsFoundations Beams
Applies Math and Science concepts to design
structures, resulting in stability and
sustainability of the structure.

5.  To archive the geometric form of the design.
 To communicate ideas between designers and
manufacturing personnel.
 To act as an analysing tool.
 To stimulate the design.
 To serve as a completing checker.
 To support large number of perspective
references.

Steps involved in
producing
Engineering
Drawings

16. Elements in
Engineering Drawings

18. Lines

19. Scales
Engineering Drawings are always to scale.
1:100
1:50
1:25
1:10
1:5

20. Dimensions
Factors to take into consideration:
method and line type that is used for dimensioning.
The linear dimension would be the overall, auxiliary
depiction and the second form of dimensioning would be
the diameter and radii of the structure.
A mixture of the two would depict the position of ‘The Hole’
in an engineering drawing.

22. - Shows the
builder and
others the
required size
for every
parts of the
building.
- Unbroken
lines.
- 2 mm away
from the
object being
dimensioned.

23. 2-Dimensional (2D)
There are multiple types of 2D Drawing Types in Structural
Engineering.
- Plan:
‘Top View’, ‘Floor Plan’ & ‘Roof Plan’
- Sections:
‘Cross-Section’ & ‘Longitudinal Section’
- Elevations:
‘Front Elevation’, ‘Right Elevation’, ‘Left Elevation’ and
‘Rear Elevation’

25. 3-Dimensional (3D)
3-Dimensional engineering drawings
are also known as ‘Production
Drawings’
The 3-Dimensional (3D) Drawing Types:
- Orthogonal Projections
- Pictorial Drawing: Isometric & Oblique
- ‘’Working Drawings’’

27. Projection
of Engineering
Drawings

28. Orthographic Projection
Orthographic projection drawings are used to
describe buildings, structures or objects pictorially.
Showed through first and third angle projection.

32. Graphical Projection
Graphical Projection drawings
have two different types:
1) Perspective projection
2) Parallel projection

34. Types of Projections
Axonometric
Isometric
Diametric
Trimetric
Oblique

36. Hatchings for Materials
Usually used in sectional views.
To show the materials of the
structure cut by the section plane.
