If you have already been using Microsoft Visio for a while, you probably have notice that many downloadable shapes contains the words: 2D, 3D or isometric. Luckily you can easily find templates on-line containing an isometric grid as its background image, such as the ones found here. Unfortunately Microsoft Visio does not support such feature, which makes this article relevant for any tool you may use. The easiest way to freely draw isometric elements is to use an isometric grid. An isometric grid can be described as an backgroud pattern of isometric shapes that can be used as a guide for your shapes and drawings. For example: Many flavours of drawing tools are currently available in the market, I opted to embed Microsoft Visio in this discussion as it turned out to be considerably popular among Information Technology engineers. To project your drawing isometrically, let’s say: a generic computer network topology, all your elements (devices, cabling, surfaces, etc) must obey this rule and as a result you will end up with the following aspect: The whole idea consists in keeping the three coordinate axes (x, y and z) equally foreshortened and making the angles between any two of them as 120 degrees. The concept of an isometric projection (from the Greek, ísos: “equal” and metrikós: “measure”), or parallel perspective, had existed in a rough empirical form for centuries as a method for visually representing three-dimensional objects in two dimensions. ![]()
