Axonometric Projection

Axonometric projection is a type of parallel projection that represents a three-dimensional object on a two-dimensional plane without converging lines of projection. Unlike perspective projection, axonometric projection maintains the true scale and proportions of the object along its principal axes, allowing for accurate measurement and clear visualization of the object’s geometry. This method is particularly useful in technical and engineering drawings where clarity and the preservation of dimensional integrity are crucial.

Axonometric projection is further divided into three main subtypes: isometric, dimetric, and trimetric projections, each differing in how the object’s axes are oriented relative to the drawing plane.

Axonometric Projection uses parallel projectors that are normal to the picture plane.

Isometric Projection

Isometric projection is the most commonly used axonometric projection, where the object is oriented such that the angles between each of the three principal axes (X, Y, and Z) are equal, typically at 120 degrees. In this configuration, all three axes are scaled equally, making it straightforward to measure and draw the object. The equal...

Dimetric Projection

Dimetric projection involves two of the three principal axes being equally foreshortened, while the third is scaled differently. This results in two of the axes appearing at the same angle relative to the drawing plane, while the third axis is at a different angle. Dimetric projection can offer a slightly more realistic view than isometric...

Trimetric Projection

Trimetric projection is the most complex form of axonometric projection, where all three principal axes are scaled and oriented differently. This approach provides a more flexible and potentially more realistic representation of the object, as each axis can be independently adjusted. However, the complexity of this projection makes it more challenging to construct and interpret...
