06.08 Blue Project Third View 2
Transcript
Learning Objective: YWBAT project the dimensions of one view onto the dimensions of the other two views of an orthographic 3-view.
Essential Question: Why are orthographic 3-views arranged in an L-shape?
Do Now: (3 min) Answer the following in your notes:
1. What must we construct before we can construct evenly spaced diagonal lines? Explain using the example of 20 degree lines.
2. We say that dimensions PROJECT if they line up between two views. For example the green dimension projects from the width of the top view to the width of the front view.
Look closely at the orthographic 3 view. Which dimension (red or blue) can we easily PROJECT from one view to the other?
Do Now: (3 min) What's Wrong Here???
In each image on the board there's exactly one thing that is being done incorrectly! Find it, write what is wrong, and explain why it is wrong and/or what to do instead!
