An axonometric view is a type of orthographic projection used in technical drawing that represents three-dimensional objects on a two-dimensional plane. In this view, the object is rotated along one or more of its axes, allowing for a simultaneous depiction of multiple sides, typically without perspective distortion. Common types of axonometric views include isometric, dimetric, and trimetric projections, each varying in the angles and scales used to represent the dimensions. This technique is useful for visualizing complex structures in architecture and engineering.
It is the plan view of your drawing rotated 45 degrees and projected upwards.
An axonometric view is useful when you want to show all three dimensions of an object without any perspective distortion. It is commonly used in technical drawings, architecture, and engineering to display objects in a clear and easily understandable way. This type of view allows for accurate measurement and depiction of the relationship between different parts of the object.
A. There is more versatility due to the fact that the drafter shows the top and side by projecting oblique lines from a frontal orthographic view. Rather than having to turn the object being sketched to make three sides visible (axonometric).
A. Axonometric and oblique drawings-three-dimensional drawings constructed without the use of perspective-are gaining popularity because they are quicker and easier to execute, and because their dimensions remain true to scale for any view. Because these views are easy to draw with instruments, they become suitable for use on working drawings.
Isometric, axonometric, and planometric are all types of projection methods used in technical drawing and 3D modeling. Isometric projection represents three dimensions in a single view with equal scaling along all axes, creating a visually balanced appearance. Axonometric projection also depicts three dimensions but allows for different scales along each axis, resulting in a more varied perspective. Planometric projection, on the other hand, presents a two-dimensional view of an object, typically emphasizing its layout or floor plan without depth representation.
Isometric view is a type of axonometric projection where three dimensions are represented in a single view, with the angles between the axes typically set at 120 degrees, allowing for a more visually engaging representation of an object. In contrast, orthographic view consists of multiple 2D projections (top, front, side) that show the exact dimensions and shape of an object without perspective distortion. While isometric views illustrate depth and volume, orthographic views provide precise measurements and details necessary for technical drawings.

Both are 3D view of an object. With perspective view, the far end of the object looks smaller (think "vanishing eye point"). With isometric view, the near and far end of the object looks the same.
Planometric is yet another drawing system which gives a 3D view. It is also known as AXONOMETRIC or PLAN OBLIQUE as it is very similar to OBLIQUEdrawing in that lines are either vertical or at 45°.The difference is that instead of the front view being a true view as in OBLIQUE; the PLAN view is the true view in PLANOMETRIC.However the plan view is drawn at 45° and the front and side views are projected upwards from the plan. The drawing opposite shows the set up.The red face, the top of the box, is identical to the plan and it is drawn exactly to size. It is basically a square which has been rotated through 45°.Planometric is very popular with architects when a plan is often the most important view.It does not however take any account of PERSPECTIVE and in this way suffers in the same way as OBLIQUE and ISOMETRIC.
Axonometric optical drawings primarily include three types: isometric, dimetric, and trimetric projections. In isometric projection, the angles between the axes are all equal, typically at 120 degrees, leading to a uniform scale along all three axes. Dimetric projection features two axes at equal angles, resulting in two scales, while the third axis has a different scale. Trimetric projection allows for all three axes to have different angles and scales, providing the most flexibility and detail in representation.
