COURSE OBJECTIVES 1. To establish the usage of basics of engineering graphics in product design. 2. To introduce the concept of product design. 3. To introduce graphics software and apply graphics software for devloping product model. COURSE OUTCOMES On completion of this course, the students will be able to

CO1: Sketch orthographic projection of points in all the quadrants and lines as per 3rd angle of projection. CO2: Drafting orthographic projection of 2D planes and surfaces using 3rdangle of projection. CO3: Draw free hand sketching of solids in isometric view into orthographic projection as per 3rd angle of projection. CO4: Sketch isometric projection of solids, and learn perspective projection of solids. CO5: Understand the concept and principles of product design using engineering graphics. CATALOG DESCRIPTION With fast changing technologies and sophistication in industry, the students need to learn product design and apply the concept of graphics in product design. In this course the students will understand the concept of design, the principles, morphology and process of design and understand the realm of engineering graphics. Next they will learn about orthographic and isometric projection of solids, freehand sketching, solid modeling techniques, different kinds of assembly, limits, fits and tolerances, and model solids using AutoCAD. At the end, the students will be doing a hands-on project applying the concepts learnt. TEXT BOOKS

COURSE CONTENT

Unit I: Orthographic projection of points and lines 12 lab hours Basic tools for graphics-Lettering-Orthographic projection- principles-Principal planes-First angle projection-projection of points. Projection of straight lines (only First angle projections) inclined to both the principal planes – by rotating line method. Unit II: Orthographic projection of plane surfaces

12 lab hours

Projection of planes- Triangle, square, rectangle, pentagon, hexagon, semicircle and circular surfaces inclined to both the principal planes by rotating object method. Unit III: Projection of Solids

13 lab hours

Free hand sketching of solids from 3D to 2D as per orthographic projection, Concept of projection of simple solids like prisms, pyramids, cylinder, and cone when the axis is inclined to one of the principal planes by rotating object method. Unit IV: Isometric and perspective projection of solids

13 lab hours

Principles of isometric projection – isometric scale –Isometric projections of simple solids– Prisms, pyramids, cylinders and cone,Perspective projection-concept. Unit V: Understanding the Concept of Product Design

10 labhours

Fundamentals of Design : Design by Evolution and Design by Innovation, Principles that govern any design, Morphology and Process of Design, Application of Graphics in Design, Introduction of software related to graphics-AutoCAD,Introduction of software related to design-Solid works.
