1. Drawing Basics
The chapter introduces the fundamentals of working drawings in civil engineering, focusing on their importance in conveying the details of structures prior to construction. It outlines standard sizes of drawing sheets, the layout and components of titles, scales used in drawings, and conventions for line work, lettering, and dimensioning. The introduction of Computer Aided Design and Drafting Systems, specifically AutoCAD, highlights the modern approach to technical drawing.

What we have learnt
- Working drawings play a crucial role in civil engineering by representing technical structures effectively.
- Standard sizes and formats for drawing papers are essential for uniformity in architectural and engineering practice.
- Computer Aided Design, particularly AutoCAD, enhances accuracy and efficiency in creating engineering drawings.
Key Concepts
- -- Working Drawing
- A technical representation of structures using drawing instruments on paper, conveying details such as shape, size, materials, and services.
- -- Title Block
- A section of a drawing that includes essential information such as the title, organization name, drawing number, scale, date, and signatures.
- -- Scale
- A ratio that represents the proportion of a drawing to the actual size of an object, facilitating easier interpretation and construction.
- -- AutoCAD
- A Computer Aided Design system that allows for precise drawing and drafting of engineering designs.
- -- Line Thickness
- The use of different thicknesses in lines to denote various aspects in engineering drawings, categorized into thick, medium, and thin.
