Isometric cube math


I am attempting to create an isometeric cube. this drawing is close but not quite right
the green and blue lines are correct (the green diamond is 2X * X)

however I’m not sure how long the RED lines should be (in relation to “X”) to make it look like a cube. the current drawing is too TALL

@DaveS, likely two issues:

  1. all red lines should be the same length as the green lines
  2. to give perspective, the two back-most green lines and the back-most red line (which appears in the top of the cube) should be a shade or weight lighter than the fore-most lines.

I hope that helps.

Kind regards, Andrew
