FoundationThe foundation comes from the geometrical
drawing.
Consists of: Plain Geometric
Drawing
Solid Geometric
Drawing

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
![Page 11: Engineering Drawing](https://reader033.vdocuments.site/reader033/viewer/2022061606/5549e6fbb4c9050d488b4bd1/html5/thumbnails/11.jpg)
Steps: 1. Engineer receives architectural drawing.
2. Produces engineering sketch (AutoCAD drawing)
![Page 12: Engineering Drawing](https://reader033.vdocuments.site/reader033/viewer/2022061606/5549e6fbb4c9050d488b4bd1/html5/thumbnails/12.jpg)
Steps: 3. Structural scheme produced.4. Approval of architect.5. Submit to authorities for approval.
![Page 13: Engineering Drawing](https://reader033.vdocuments.site/reader033/viewer/2022061606/5549e6fbb4c9050d488b4bd1/html5/thumbnails/13.jpg)
Steps: 6. Proceed to construction.7. Amendments of construction
drawings.8. As-built drawings drawn.9. Certificate of Completion and
Compliance awarded.

Elements in Engineering Drawings

LinesThe difference in lines represent different
meanings in an engineering drawing.
Types: Construction LinesThick active linesThin active linesHidden linesCentre linesBreak linesUnderground pipe linesDimension lines

DimensionsFactors 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’’

OrientationTo show the direction of
north relative to the plan.
Level MarksTo show the height of ceiling, etc

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 projection2) Parallel projection
![Page 33: Engineering Drawing](https://reader033.vdocuments.site/reader033/viewer/2022061606/5549e6fbb4c9050d488b4bd1/html5/thumbnails/33.jpg)

Perspective Projection
Perspective Projective drawing is a linear projection where three dimensional objects are projected on a picture plane.This has the effect that distant objects appear smaller than nearer objects.
Types: - One-point projection.- Two-point projection.- Three-point projection.
![Page 35: Engineering Drawing](https://reader033.vdocuments.site/reader033/viewer/2022061606/5549e6fbb4c9050d488b4bd1/html5/thumbnails/35.jpg)

Methods & Rules of Projection
Method:1. Select a view from the best position. 2. Observe the overall structure.3. Note: parallelism, proportions and alignment.
Rules of Projection: 4. Parallel lines remain parallel.5. Proportions remain unchanged.6. Circles are always ellipses with the major axis of ellipse
perpendicular to the polar axis of circle.7. Transformation of 90°angles.

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