1. Graphics 1: Isometric Sketching and Coded Plans
ENGR 1182

2. Today’s Learning Objectives
Develop visualization skills using coded plans and snap cubes
Use coded plans to sketch objects in isometric view

3. Isometric Sketches
Isometric sketches represent 3D objects in 2D space. They are made as if you are looking down the diagonal of a cube. Shapes and angles are distorted equally in isometric view.

4. 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.

5. Isometric Sketches from Coded Plans
Lines are only shown where surfaces intersect.
Hidden edges are not shown in isometric view.
Coded Plans - SOLIDWORKS Part, Drawing & PDF available
The Instructor may optionally use the supplied SOLIDWORKS part to enhance the students visualization of the Coded Plan. The part can be rotated as an optional preview of the upcoming Graphics 2 presentation on Isometric Sketches from Different Viewpoints. The SOLIDWORKS drawing is also supplied as an optional preview of the upcoming Graphics 3 presentation on Orthographic Projection Basics.

3D objects can be represented in 2D by sketching is isometric view.
Coded plans are a blueprint for drawing simple objects.
Lines are drawn only where surfaces intersect, and hidden features are not shown.
