Chapter 09 sectionนายสุรพันธ์ รักษาพราหมณ์This document discusses section views in engineering drawings. It begins with an introduction and overview of section views and their purposes. Then it discusses terminology and common practices used in section views, including cutting planes, cutting plane lines, and section lines. It describes different types of section views such as full sections, offset sections, half sections, broken-out sections, revolved sections, and removed sections. Examples are provided to illustrate these different types of section views. The document concludes with guidelines for dimensioning features in section views.

Chapter 07 dimensioningนายสุรพันธ์ รักษาพราหมณ์This document discusses dimensioning practices for engineering drawings. It begins by defining dimensioning as specifying a part's sizes, locations, materials, tolerances and other information using figures, symbols and notes. It then covers components of dimensioning like extension lines, dimension lines, leader lines and dimension figures. Specific guidelines are provided for dimensioning various geometric features such as arcs, cylinders, holes, chamfers and rounded ends. The document concludes with recommendations for placement of dimensions, such as avoiding crossing lines and dimensioning hidden lines.
Chapter 01 introductionนายสุรพันธ์ รักษาพราหมณ์This document provides an overview of engineering drawing standards and techniques. It discusses orthographic projection methods including multiview and axonometric drawings. Key topics covered include line types, lettering standards, scale conventions, and traditional drawing tools. Proper techniques for graphics language, word placement, letter spacing and stroke sequence are explained to ensure effective technical communication through engineering drawings.
Chapter 03 orthographic projectionนายสุรพันธ์ รักษาพราหมณ์This document discusses orthographic projection and multiview projection techniques. It covers topics such as object representation, line conventions, and projecting points, lines, planes and objects. Specifically, it explains how to obtain multiview representations of an object by revolving the object or moving the observer around it. It also describes techniques for projecting object features and maintaining proper line conventions regarding visible, hidden and center lines.
Engineering Drawing: Chapter 12 working drawingmokhtarThe document discusses working drawings which include detail drawings of individual parts and assembly drawings of assembled parts. Detail drawings show dimensions and notes for manufacturing a single part, while assembly drawings show the functional relationship and relative positions of parts. Assembly drawings include exploded views, general views, and detailed views. They provide information like a parts list, dimensions, and section views to clarify part mating. Leader lines and balloons are used to identify parts. Interpreting assembly drawings involves understanding the assembly steps, part functions, and design concepts.
Using Drawing Tools and applied geometryNUST StuffThe document discusses tools and techniques for technical drawing. It covers:
1) Preparing drawing tools like fastening paper to the drafting board.
2) Using tools like the T-square, compass, and templates to draw straight lines, arcs, circles, and at angles.
3) Applying geometric techniques to bisect lines and angles, draw parallel and perpendicular lines, and construct tangents and fillets.
Chapter 03 orthographic projectionนายสุรพันธ์ รักษาพราหมณ์This document discusses orthographic projection and multiview projection techniques. It covers topics such as object representation, line conventions, and projecting points, lines, planes and objects. Different projection methods are described including parallel, oblique orthographic, and axonometric projections. Guidelines for visible, hidden and center lines are provided.
Chapter 03 orthographic projectionนายสุรพันธ์ รักษาพราหมณ์This document discusses orthographic projection and multiview projection techniques. It covers topics such as object representation, line conventions, and projecting points, lines, planes and whole objects. Different projection methods are described including parallel, oblique orthographic, and axonometric projections. Guidelines for hidden lines, center lines and other line conventions in multiview drawings are also provided.
Chapter 02 using drawing toolsนายสุรพันธ์ รักษาพราหมณ์This document discusses tools and techniques for technical drawing. It covers:
1. Preparing drawing tools like sharpening pencils and adjusting compasses.
2. Using tools like T-squares, triangles, and compasses to draw straight lines, arcs, circles, and shapes at specific angles.
3. Applying geometric techniques - how to bisect lines and angles, draw parallel/perpendicular lines, tangents, and ellipses.
