Isometric Projection

Isometric Projection

What is Isometric Projection?

Isometric Projection is the preferred method of representing an object in 3D as it allows for a more realistic representation of the object when compared with Oblique Projection.

When a product is drawn in Isometric Projection it is drawn 'corner on' rather than 'front on' as in Oblique Projection. It is also important to note that you use scaled measurements throughout the drawing and do not need to half any measurements (like you had to with Oblique Projection).

As the product is drawn corner on, lines run off from the corners of the object at 30 degree angles and both to the left and right - this differs from the 45 degree angle lines drawn to one side as used in oblique.

Please see the examples below of a simple cube drawn in isometric and in oblique.

Formative Isometric Projection Task

To start learning how to draw in Isometric Projection you will work as a class to draw one of the pre-cut wooden blocks in Isometric Projection. You will also participate in taking measurements from this wooden block and will guide your teacher as he draws the example on the board (You will also follow along and draw it at the same time on your drawing board).

Summative Isometric Projection Task

You will select 3 from the range of wooden blocks and will draw these in Isometric Projection. Your assessment for Isometric Projection will be based on how accurately you can draw these three Isometric Projection drawings that you complete.
