  1. Introduction To EngineeringCommunication by Sketching and Isometric Pictorials - 1 Agenda Understand graphics as a communication tool Make a first 3-D and 2-D sketch

  2. Reference Materials • Introduction to Graphics Communication for Engineers (IGCE) by G. R. Bertoline • 1st Chapter – Introduction to Graphics Communications • 2nd Chapter – Sketching and Text (through Section 2.4.1 for today)

  3. Attempt in teams of two persons to describe the part below in words only. Write your description on a sheet of paper.Q: Would this be an effective way to tell someone how to build this part?

  4. Chap 1 Topics to Note • Reasons for Technical Drawings • Tools for Technical Drawing • Traditional • Computer Based • Alphabet of Lines

  5. Chap 2 Sketching and Text • Types of Technical Drawings • Advice on Freehand Sketching • Introduction to Projections

  6. Three Basic Types of Technical Drawings • Freehand sketches • Instrument drawings • Computer drawings and models

  7. Advice on Freehand Sketching • Orient paper to be comfortable • Mark end points of the lines to be sketched • Relax and draw in direction comfortable to you • Draw long lines as a series of short lines • Use grid paper when available

  8. Introduction of Projections: Our challenge is to present 3-D objects with 2-D media • Two Basic Categories Multi-view Pictorial

  9. TOP RIGHT SIDE FRONT Assignment A: First Sketch • On a plain sheet of paper • Sketch a multiview (front, top, & right side) drawing of the object in slide #3 • Sketch an isometric drawing of the object in slide #3
