An isometric drawing is a type of technical drawing that shows an object with equal measures on three axes at 30 degree angles to give the impression of three-dimensions on a two-dimensional plane. It is constructed using a horizontal line intersected perpendicularly by a vertical axis, with two additional axes at 30 degrees to the left and right that allow lengths to be marked off and connected in a way that suggests depth.

1. Isometric Drawing
- it is a kind of drawing which is derived from
two Greek words ISO meaning equal
and METRIC means measure.
- it also means equal measure
- it is constructed on three axis namely the
vertical axis, the 30-degree left cross axis
and the 30-degree right cross axis.
