Oblique Projection
The drawing preserves:
The drawing does not preserve:
- the relationship between the lengths of the edges of the cubes - all edges are equal in reality, but not on the drawing
- the angles between them - all edges are right angles in reality, but some are 45 degrees on the drawing
- perpendicular lines - because not all right angles are preserved
Advantages of oblique projection include that it is straight-forward to draw, and the relationship of each cube to the others is clear.
Disadvantages include the number of features of the original structure which are not preserved.
