Isometric drawing is the method which is used to represent the 3D object in 2D using the vertical lines that are drawn vertically and horizontal lines that are drawn at 30 degrees to the base. Usually, in an isometric drawing, there are two sets of lines - parallel and those that are not parallel. The isometric view of the object is drawn from a direction where the angles between the projection of the x,y, and z planes are equal to 120 degrees.
