Clicking a square in the control screen will add a block to the grid. Use your right mouse button to remove a block. This program helps you build block-models and its main aim is to help you draw a variety of views.

(This demo only allows you to build small towers of up to two blocks high. The licensed version also allows you to work in realistic perspective and with random heights.)

Click on [control line of view].

Place the mouse over the drawing and drag it while holding the left mouse button. The viewpoint of the drawing changes and now you can see what the front, side and top view look like.

After you have drawn these views, you can look up the answer and see whether your answer was correct. This view screen allows you to temporarily render certain views invisible so that you can check one view without already seeing the others. There is also the option of including measure tools used for measuring lengths, angles and surfaces but we will discuss that later.
