It is the process of Representing a Figure| a Shape | any Landscape or Building of Real life on the 2 dimensional plane.
In an isometric view, parallel lines don’t converge anywhere, they are seen as parallel. This is because each axis is being represented with the same Magnitude [Length].
If you were to start a picture by taking 1 unit in the Y axis, then you must take the same length along the X and Z axes too. This is what Isometric image to be more useful when it comes to depicting accuracy.
With Isometric drawing you can Bring a 3 Dimensional Object on to a 2 Dimensional Plane. Isometric drawings are the reasons as to how Video games were able to achieve much popularity.

Points to Remember
All Spatial Metrics are Equally Scaled. When we say, Spatial Metrics, we mean, the Length, the Height and the Depth, which on a figure is represented by the X-axis, Y-axis and the Z-axis.
