  • 1. Introduction to Drawing ( ITD ARC30103 ) Lim Joe Onn Jaclyn Hwang Jeff Ong Natalie Ki Pang Khai Shuen Structural Engineering Drawings

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. 4. 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. Importance 5. Thank You Steps involved in producing Engineering Drawings 6. Elements in Engineering Drawings 7. Lines 8. Scales Engineering Drawings are always to scale. 1:100 1:50 1:25 1:10 1:5 9. 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. 10. - Shows the builder and others the required size for every parts of the building. - Unbroken lines. - 2 mm away from the object being dimensioned. 11. 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 12. 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 13. Projection of Engineering Drawings 14. Orthographic Projection Orthographic projection drawings are used to describe buildings, structures or objects pictorially. Showed through first and third angle projection. 15. Graphical Projection Graphical Projection drawings have two different types: 1) Perspective projection 2) Parallel projection 16. Types of Projections Axonometric Isometric Diametric Trimetric Oblique 17. Hatchings for Materials Usually used in sectional views. To show the materials of the structure cut by the section plane. 18. Thank You Thank you. 19.
