1. Basic Isometric Sketching and Coded Plans
Chapter 2 of Text

2. Objectives Understand the basics of the isometric sketching
Create basic isometric sketches using snap cubes and coded plans

3. Isometric Sketches
Isometric sketches represent 3 dimensional objects in 2D space.
all 3 dimensions are shown equally
Iso is from the greek for “the same”
To demonstrate, have students pick up a snap cube and look down the cube’s diagonal to see all three dimensions equally.
Isometric grid and dot paper
Isometric coordinate system

4. Isometric Sketches
Isometric sketches are made as if you’re looking down the diagonal of a cube.
Diagonal of the cube
End view of the diagonal
Note that when we look down on the cube like this, the right angles appear distorted.
The square sides of the cube now look like parallelograms.

5. Coded plans
Coded plans define simple objects which can be made from blocks.
Each number represents how tall the stack of blocks is at that location.

6. Isometric Sketches from Coded Plans
Lines are shown only where surfaces intersect.
Hidden edges are not shown.

7. Isometric Sketches and Coded Plans
Use this time and your snap cubes to practice building objects and sketching in isometric perspective using coded plans.
