Learning Objective: YWBAT create an orthographic 3-View from an isometric view.

Essential Question: Why are isometric views useful in drafting?

Unit 4: Engineering

Do Now: Today we're going to complete our first orthographic 3-view from an isometric drawing.

What is an isometric drawing?

After you've set up your border and title block, which orthographic view - top, front, or side - should you start with? Why?

How should you determine where to start that first view?

Line Exercises

Multi-view Drawings

Due today:

Part 1 - Create a drafting template (border and title block).

  • Go quick! This should take no more than 5 minutes.

Part 2 - on your template, create the orthographic 3-view from the given isometric image.

  • Dimensions on your orthographic 3 view should match those on the page.

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.
