Axonometric projection is a type of parallel projection used in technical drawing and engineering design to represent three-dimensional objects on a two-dimensional plane.
In axonometric projection, the lines of sight from the viewer to the object are parallel to each other, and the object is rotated to show three of its faces simultaneously.
The three types of axonometric projections are isometric, dimetric, and trimetric, depending on the angles at which the object is rotated.
Isometric projection is the most common type of axonometric projection and is used to represent objects that are symmetrically aligned along three axes.
In isometric projection, all three axes are shown equally foreshortened, and all angles between the axes are 120 degrees.
Dimetric and trimetric projections are used when objects are not symmetrically aligned along three axes.
In dimetric projection, two of the three axes are shown at different foreshortened angles, while the third axis is perpendicular to the plane of projection.
In trimetric projection, all three axes are shown at different foreshortened angles, resulting in a more realistic representation of the object.
Axonometric projection is useful in technical drawing and engineering design because it allows the designer to show multiple views of an object in a single drawing, making it easier to understand the object's shape and dimensions.
However, axonometric projection does not accurately represent the relative sizes of different parts of the object or the perspective distortion that occurs in real life, so it is not suitable for creating realistic or artistic representations of objects.
