To explore plans and elevations you can use Wisweb applets from the Freudenthal Institute.
Try Cube houses to build 3d models and generate different views.
First select drawing to see the view then select 3d-model to give you a model you can rotate and look at the different views.
There are eight different models you can explore (use the drop down menu).

Building Houses allows you to create buildings and see the plan, front and side elevations as you build. (If that link does not work – try this).

You can add (build) or remove (break down) bricks and control the size of the square base.
Building houses with side views challenges you to construct 3D models given the plans and elevations; the task is made more challenging by specifying that as few cubes as possible should be used.

Note that in order to achieve the minimum number of cubes, ‘floating’ cubes are needed. You could build a solid model to begin with then see if you can remove any cubes.

building houses does not seem to be working any more. Any idea why?
You are right Nic – how strange. I have now given an alternative in the post above.
this just comes up with java and never loads?:S
That’s strange Chloe – I just tried all the links and they were slow but did eventually load. I’m not sure what has happened here – they used to load quickly. I will investigate further.
It comes up with this:
Helaas, Java is niet geinstalleerd of staat uit .
=D
You do need Java installed for these applets Anastasia otherwise they will not run.
not working for me either, even with java updated and installed
