What am I doing here? This is a brief introduction to scientific and technical graphics. Every experimental scientist and engineer has to make drawings as part of the process of their work, and they are the main method of communication with machinists and other manufacturers. In this course, you will learn the basic rules of freehand sketching and lines types, creating isometric drawings and other projections, 3-view machinist’s drawings, dimensioning and tolerancing, symbols, threads, sectioning, vector graphics and layering in Office, color models, creating and editing raster images (photographs) using GIMP and imageJ, creating animations in PowerPoint, plotting computational results in Mathematica and with “design mode” in Excel, and using “Sketchup” for 3D modeling

Can I get a book? Sure! But you don’t have to. The standard text for machinist’s drawings is Technical Drawing, by Giesecke, Mitchell, Spencer, Hill, etc. (Prentice Hall Publishers). The current edition is the 12^th, (ISBN 0-13-008183-3) but any edition would be good enough.

Do I need to buy anything? NNot really. In a ‘real’ drawing class, you’d have to buy a lot of stuff, including a drawing table, a T-square, some architects rules, erasing shields, a ‘French’ curve set, and lots of other things. For this overview course, I think you should have the following:

a good ruler                               a 30-60° triangle

some pencils                              a bow compass 

a circle template                        a good white eraser

some clean white paper             an isometric ellipse template

We’ll make do with these things. Many are available in the college bookstore, or at WalMart. The compass and templates might be the hardest to find; I found each at Staples.

                                    Assignments:                60%

                                    Participation:                20%

What software do I need? You need Microsoft office, NIH ImageJ, Gnu GIMP, Trimble Sketchup, and Wolfram Mathematica. All this software is either free or already provided by the college for you.

Assignment Summary:

In accordance with college policy, you should expect to work on the assignments for an average of 2 hours per week throughout the semester to be able to pass this course. A few weeks will be shorter than that, and a few weeks longer than that. For multi-week assignments, you should not expect to complete the assignment in a single day. 

Learning Outcomes 

At the end of this course, students will:

 

• Be able to identify appropriate techniques used in machinist’s drawings.
• Be able to create adequate 3-view machinist’s drawings.
• Be able to make adequate isometric drawings and scientific diagrams by hand and in Microsoft office.
• Understand the basics of scientific photography.
• Be able to manipulate and edit scientific raster images in GIMP, including the use of alpha channels.
• Be able to make measurements from scientific images using ImageJ.
• Make scientific animations using PowerPoint, Excel, and Mathematica.
• Create 3D models in Sketchup.
