Picture of How to make a Tesseract in Sketchup
This instructable will show you how to design a Tesseract in Sketchup. A Tesseract is '...the four-dimensional analog of the cube...'. (From http://en.wikipedia.org/wiki/Tesseract). To complete this instructable, you will need a basic - moderate knowledge of how to use Sketchup.

Step 1: You Will Need

For this instructable, you will need:

1. A computer with the following specifications: http://support.google.com/sketchup/bin/answer.py?hl=en&answer=36208

2. Sketchup installed on the above computer. If you don't know how to install software then maybe try an easier instructable. If you don't have Sketchup installed then look here: http://www.sketchup.com/intl/en/download/

3. 30 minutes to 1 and a half hours depending on you previous knowledge of Sketchup and how quickly you work. (The first time took me about 2 hours to work out where I was going to start and the best way to construct it).

4. A mouse. Trust me - invaluable.

Step 2: Open Sketchup

Unless you have disabled it,, when you first open Sketchup you will see the 'splash screen'. The first thing you want to do is set the template. As I'm Australian, I prefer to use metric (millimetres) unless I'm working on a bigger project like furniture. (6 feet seems easier to visualise than 182.88 cm). I find that apart from the units, it doesn't really matter which template you use (also, if you choose inches and want to input a value in millimetres, all you have to do is add the desired suffix to the value and Sketchup will automatically change it for you). However for perfection's sake we will choose Product Design and Woodworking. If this step is too complicated for you, I suggest using a search engine (please tell me you know how) to find some easier tutorials to start off with).

Step 3: Starting the model

Follow the text and look at the picture if something is not clear:

Firstly, once the 'creation window' has opened, click on the Rectangle/Square tool.
Click on the Origin with the rectangle tool selected.
Use the rectangle tool to create a square 50mm by 50mm.

you should add this to the free 3d printing group to get it made for free:
nice step by step instructions!

Thankyou, will do. First ible so wasn't sure how it would go.

Technically, it's not a tesseract unless it can be rotated in four dimensions. As sketchup only supports 3 :( its impossible to make a real one. Basically, if you rotate this, it should look like it's cycling the inside cube to the outside, and vis versa. You probably know this, but I'm trying to avoid having someone else saying that this is "4D", then arguing about it with someone else, or me.

Well, you can make a model that will act like one on a computer, for example http://tomkail.com/tesseract/
Just thing of this version on sketchup as a "drawing" of a 4d model, like a cube on paper

Hi jduffy54, yes I do know that technically, a tesseract is a 4d shape, as it is only possible to represent this in an animation, I was going for the 'frozen in time' look for the model. Perhaps someone with animation experience will be able to expand on this and create an 'ible for creating an animation of an actual tesseract. Meanwhile we will have to live with the limitations of model building software like Sketchup.
Yeah, I use sketchup too. There is an animation thing you can do, but I'm not sure if you can move the model in it.
