Isometric Drawings
Isometric Drawings
To communicate important details and technical information about your ideas and designs, you need to be able to visualize those ideas and represent them in a way that others can understand. To imagine in three dimensions you need to build spatial visualization skills. The ability to visualize in three dimensions is important to many careers, particularly careers in STEM disciplines. Research shows that practicing and improving spatial visualization skills improves success in college engineering programs.
Engineers and designers often sketch an isometric view to communicate information about objects because an isometric sketch appears three-dimensional. An isometric sketch is a type of technical drawing, therefore it should include all important information about the object. An isometric view appears three-dimensional because three sides of the object are shown—width, depth, and height.
The figure on the right shows the orientation of the axes in an isometric view and identifies the orientation of the front, right side, and top of the object. Sketching isometric views freehand is a useful skill when conceptualizing or sharing an idea and helps improve your spatial visualization skills.
Isometric Sketch Characteristics
Isometric Sketch Characteristics
The sketch appears three-dimensional because three sides are shown.
All principal dimensions (width, depth, and height) are represented in true proportion.
Width and depth lines are drawn at 30 degrees from horizontal.
All height lines are vertical.
The shapes of the object faces are distorted (not represented as true shapes).

Shading
Shading
All of your isometric drawings should be shaded. Use the cube to the right as a reference.
Front = Dark Shading
Right = Light Shading
Top = No Shading
*use your best judgment for curves or diagonal faces - just keep it consistent
