Definition of Axonometric projection:
Three-dimensional architectural drawing of a building in which visible elevations are based on the floor plan. Such drawings, although true to scale, are incorrect in terms of perspective because all lines remain parallel instead of receding to a common vanishing point.
Parallel projection in which an object appears to be rotated to show its all three dimensions. Axonometric projections are classified according to how the principle axes are oriented relative to the projected surface. Isometric projection is a type of axonometric projection.
