The picture below shows three views of a figure from the front, right, and top. The entire figure uses a total of seven cubes. Can you construct the figure using the isometric drawing tool? (Be sure to use cubes of the proper color, too.)
You should be able to choose any of the 8 potential orientations, with a orthographic projection, and get a perfect isometric view of your model. Just follow the math in your referenced Wiki article for setting up the view matrix, and do an orthographic projection for your projection matrix, and you're all set.

Recently, PlantPerson and I were chatting about the potential of isometric games in Blender. When Plant suggested that it might not be possible to make a proper isometric camera in Blender, I decided to take it as a challenge
Setting Up a True Isometric Camera
To set up a true isometric camera in Blender, open a new scene and select the camera. Press the N key over the 3D Viewport in order to bring up the Transform Properties window. Now change the rotation settings as follows:
Hi Everyone,
Im glad i found this thread as ive been trying to figure out why my orthographic camera was zooming in when I moved it and now i know. Ive tried your fake isometric camera blendenzo which is lots better for me but still doesnt make the scene look quite right.
I was hoping one of you may have made some progress with this? While looking through the gameengine API i found this code but cant get it to work with my camera ( all the objects disappear- maybe its just making the camera look somewhere else?) I hope the code is some use to one of you?
Perhaps you can help me understand why you are even interested in an isometric view. The several forms of axonometric projection, including isometric, were developed as a means to produce a pictorial image of an object as a simplified alternative to true perspective, back when it was prohibitively difficult and time consuming to draw a true perspective in most cases, although they were clearly preferable. The trade-off was, isometric views appear distorted and unnatural, although they are relatively easy to draw by hand with a 30-60 triangle.
I think that instead of saying SketchUp has lots of problems with its parallel projection subsystem, I should have said it has one long-standing graphical bug that causes loads of problems for users who find that sort of camera more conducive to their workflow.
It is impossible to convert a drawing created in isometric projection to a 3D drawing as the isometric projection is only a method of visually representing 3D. The 2D elements in a isometric projection have no intelligent 3D co ordinates.
Ian is correct. You can't really rebuild a 3D model from 2D linework via conversion, especially with piping isometrics because they are not to scale. The drawing in your screenshot appears to be generated, not drawn, perhaps with AutoPLANT, OpenPlant, PDS, or some such system. Those products would have the 3D model used to create the isometrics.
I've got a problem or two with an AD thing I'm working on. This old console telly is one of the elements in a project I've set myself (details below).First, the different planes just won't butt up precisely: there's always a tiny gap, even though the stroke is turned off. I've found this before, and I don't think it's a side-effect of using the isometric projection.Second, how can I get a curved edge between the top panel and the sloping front and get the bitmap fill to follow the curve?
Isometric drawing, sometimes called isometric projection, is a type of 2D drawing used to draw 3D objects that is set out using 30-degree angles. It's also a type of axonometric drawing, meaning that the same scale is used for every axis, resulting in a non-distorted image. Since isometric grids are pretty easy to set up, once you understand the basics of isometric drawing, creating a freehand isometric sketch is relatively simple.
This post explains all you need to know about isometric drawing. You'll learn exactly what defines an isometric drawing, how it differs from one-point perspective, what to do to get started creating your own isometric projection, and even more. Elevate your art skills further by following the tutorials in our how to draw guide (which will teach you how to draw pretty much anything).
From The Other Wiki: Isometric projection is a form of graphical projection, more specifically, a form of axonometric projection. It is a method of visually representing three-dimensional objects in two dimensions, in which the three coordinate axes appear equally foreshortened and the angles between any two of them are 120 degrees.
In the days before true 3-D graphics, isometric projection was one of the ways artists suggested depth. Developed and formalized in the 19th century for technical and architectural drawings, it remains a popular way of creating 3-D-esque graphics in video games, especially for handheld systems.
Of course, in many cases in video games, the projection is not actually isometric in the mathematical sense, because a 26.57 slope is much easier to draw on square pixels than a 30 slope.note A right angle triangle where one acute angle is 26.57 has a corresponding side whose length is exactly half of the length of the other side. But that would be nitpicking, so these games are called "isometric" anyway. The term can also refer to the vastly different Trimetric Projection (such as in Fallout and Fallout 2 or SimCity 4), where all three angles are different.
