Isometric drawings have a clear distinction from the other two wherein it has all dimensions to the same scale. There are three types of axonometric drawings - isometric, dimetric, and trimetric. It is also different from a two-point perspective in that an axonometric drawing shows three sides of an object while the two-point perspective only shows two sides of the project with lines heading towards the vanishing points. Isometric drawings are also axonometric, but what exactly does that mean? Axonometric drawings, or perspective or axonometry, is an orthographic projection to represent 3D objects with an oblique plane. Interestingly, this means there is no horizontal line in an isometric drawing. Any non-vertical lines are constructed at an angle of 30 degrees from the horizontal axis. F.D.K, 1995, A Visual Dictionary of Architecture).
It is a paraline drawing with all the lines parallel to the principal axes drawn at real lengths and same scale (Ching.
Derived from Greek meaning ‘equal measure’, isometric drawings are not distorted as the foreshortening of the axes is equal. What is An Isometric Drawing?Īn isometric drawing is a type of axonometric drawing, based on the isometric projection, that has the same scale on all three axes (X, Y and Z axes). Let’s find out more about these drawings and how you can use them in your projects. Despite the lack of such details, isometric drawings are still relevant and useful in architecture.
