Difference between Isometric, Oblique and Orthographic Drawing

Isometric Drawing:

Oblique drawing:

Orthographic Drawing:

Isometric drawings  are three dimensional drawings while oblique drawings are two dimensional images of three dimensional objects. An Orthographic drawings are basically the same as an oblique drawing but the difference between these two drawings is that when an orthographic drawing is projected, six different pictures of the object can be seen whereas an oblique drawing is just a two dimensional image of an object.
