Difference between Isometric, Oblique and Orthographic Drawing

An Isometric drawing is a method of visually representing three-dimensional objects in two dimensions, in which the three coordinate axes appear equally foreshortened and the angles between any two of them are 120 degrees. It is used in technical and engineering drawings.

An Oblique drawing is a simple type of graphical projection used for producing pictorial, two-dimensional images of three-dimensional objects.

An Orthographic drawing is a means of representing a three-dimensional object in two dimensions. It is a form of parallel projection, where the view direction is orthogonal to the projection plane, resulting in every plane of the scene appearing in affine transformation on the viewing surface.
