Engineering 1182Isometric SketchesIsometric sketches represent 3 dimensional objects in 2D space.

Isometric coordinate systemIsometric grid and dot paperEngineering 1182all 3 dimensions are shown equallyIso is from the greek for the same

To demonstrate, have students pick up a snap cube and look down the cubes diagonal to see all three dimensions equally. 3Isometric SketchesIsometric sketches are made as if youre looking down the diagonal of a cube.

Diagonal of the cubeEnd 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. Engineering 1182Coded plansCoded plans define simple objects which can be made from blocks.Each number represents how tall the stack of blocks is at that location.

Engineering 1182Isometric Sketches from Coded PlansLines are shown only where surfaces intersect.Hidden edges are not shown.

Engineering 1182Isometric Sketches and Coded PlansUse this time and your snap cubes to practice building objects and sketching in isometric perspective using coded plans.
