WHAT ARE STRUCTURAL

ENGINEERING DRAWINGS?

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.

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.

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.

- Shows the

builder and

others the

required size

for every

parts of the

building.

- Unbroken

lines.

- 2 mm away

from the

object being

dimensioned.

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’

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’’

Projection

of Engineering

Drawings

Orthographic Projection

Orthographic projection drawings are used to

describe buildings, structures or objects pictorially.

Showed through first and third angle projection.

Graphical Projection

Graphical Projection drawings

have two different types:

1) Perspective projection

2) Parallel projection

Types of Projections

Axonometric

Isometric

Diametric

Trimetric

Oblique

Hatchings for Materials

Usually used in sectional views.

To show the materials of the

structure cut by the section plane.
