Manual Drafting Test: Thursday or Friday, March 3 and 4. After that, we start CAD!
Scales: for 1 and 3, use .25in = 1 grid square; for 2 use 10 cm = 1 grid square |

I'd like to spend 4 class days finishing the speaker project and completing manual drafting through orthographic projections and isometric drawings.
The Learning Objectives for this unit are:
-- Know how to create a standard orthographic projection drawing for a 3-D shape.
-- front, top and right side views in the correct location and lined-up
-- correct use of scale
-- correct line types including visible, hidden and centerlines
-- drawing name, your name, and scale properly labelled on the drawing
-- Know how to create an isometric drawing of a 3-D shape
-- understand the isometric axes (30 degree lines) and scale
-- Be able to create an isometric drawing from orthographic projections and vice versa
-- Figure out missing views from a combination of both kinds of drawings
Each class will be divided into 3 groups. 1 group will rotate through the soldering and cutting stations while the other two work through drawing exercises.
0. Take the pretest in Edmodo.
1. Orthographic Projections: Complete Steps 1 - 7. ** Watch the extra video if needed.
2. Choose 2 of the 3 isometric drawing files above and draw the orthographic projections.
3. Watch Isometric View from Orthographic Projections by Prof Jeff
4. From your orthographic projections in #2, use isometric drawing paper to create the isometric drawing. Compare to the original.
5. Turn in both orthographic drawings and isometric drawings by the end of your second class day this week.
There will also be some self-paced worksheets for missing views, as well as some 3-D shapes to work on before the manual drafting test.
