Ultimate meaning of isometric drawing – design a cube house at scale The meaning behind isometrics is that you express volume, as well as the general three dimensional object.įor shadows there are a couple of repetitive patterns which I describe in one of my exercises on drawing an isometric 3. Truth be told, there is no isometric drawing out there that will look right if it does not have cast shadows. The next level of understanding is to get how cast shadows work for an axonometric. Isometric axonometrics are by far the most popular and have all three axees at 120 degrees distance from each other, with the same unit of measure for all three axes. In real life everything we see is in perspective and, hence it cannot have a scale or it cannot be measured in any way. This coordinate system varies for each type of drawing and can have different units of measurement along each axis.Īxonometric actually means ‘measured by axees’ and it is a very affordable way of drawing a three dimensional technical volume that has scale and represents the specific architectural volume or composition in a measurable way which would not be possible otherwise. Isometric projection as we know it has been invented by Professor William Farish (1759–1837) in the XIX century and has been an invaluable tool for architects and engineers to use in their work.īy definition, an axonometric drawing is a three dimensional technical drawing where all the dimensions of the projection are drawn in reference to a coordinate system. Time to talk about isometric perspective and what is the meaning of isometric drawing.
