Isometric Drawing

Stage: 3 Challenge Level: Challenge Level:1

If you are not familiar with Isometric Perspective, start by reading our article 3D Drawing.

axes on isometric paperThe diagram on the right shows a set of three coordinate axes on an isometric drawing.  What is the angle between each pair of axes?

Because the angles between the three axes are all the same, each one must be 120 degrees. 

Is it possible to keep the distance between all adjacent grid points equal, and have some other angles between the axes?

The photo below shows a multilink structure.  Draw it on isometric paper.  

Which properties of the original structure does your drawing preserve, which are not preserved?  You should think about:

  • the relationship between the lengths of the edges of the cubes
  • the angles between them
  • parallel and perpendicular lines
