06.10 Yellow Three View from Isometric 1
Learning Objective: YWBAT create an orthographic 3-View from an isometric view.
Essential Question: Why are isometric views useful in drafting?
Perspective View: lines do NOT have equal scale. Lines that go into the distance converge.
Do Now: (3 min) 1. What is the difference between PERSPECTIVE and ISOMETRIC VIEW?
2. Which of the views below are isometric? Which are perspective views? How can you tell?
Isometric View: all lines have equal scale. As a result, lines that go into the distance are parallel.
Unit 6: Manual Drafting
From Isometric to Orthographic
- In order to get to today's assignment, you and - if you choose - your partner will watch a 3 minute video (log into Google Classroom).
- On the back of your Do Now is 4 questions.
- All 4 must be answered correctly to move on to the next assignment.
After completing the questions, raise your hand and I will give you the assignment.
Part 1
Due today:
Part 1 (15 min) - complete the worksheet. On it, you will:
- Identify the faces of each view.
- Freehand sketch each view orthographically.
- Label the dimensions along each edge of each view.
Part 2 (10 min) - Create a drafting template (border and title block).
- Work quickly on this step! Once taped into place, it should take 5 minutes or less!
We will clean up completely at 9:52am! Be sure to return to your seat. We'll have one final check before being excused.
Isometric view: a 3D view in which ALL lines have equal dimensional weight.
Part 2
3-View Orthographic Projection from an Isometric View
Isometric: a 3D view in which there is no vanishing point. In other words, lines of the object do not converge, making lines along each appear to have equal dimensional weight.
