Select the cube, face, or segment along the left navigation.

Then, place the object on the grid where you want it. If your selection is red, on the grid, then it is a location where you can not place the object.

HINT

Draw your shape from back to front and from bottom to top, to assure proper alignment of cubes.

When adding adjacent cubes, be sure to click on the face of the cube you want to be touching.

Create Mode

There are two ways to move objects:

1. Using the Arrow. Simply select and drag the object(s) to a new location.

2. Unit Movement Buttons

The other buttons along the top navigation serve various functions:

Rotate the entire figure by dragging the image or by using the sliders.

Use the Eraser to erase individual objects. You can also select multiple objects with the Pointer and then use the eraser to erase those objects.

Explode- Change all cubes into faces. If two cubes share a face, the face will not be shown. Note that you can not undo this action.

Use the Paint Brush to select a color before you create an object. You can also change the color once an object is created by selecting the object with the color you wish it to be.

Inspect Mode

In the Inspect Mode, you can:

See a 3D or 2D version of your isometric drawing.

Print your isometric drawing, as it is shown in the workspace.

Rotate your isometric drawing.

Choose to display your isometric drawing with or without axis.

Choose to display a solid or transparent isometric drawing.

You can reset all the view at any point by choosing the Reset View button.

# data[].attributes.attachment_link.readable_text
Would you like a personalised pencil case which is exactly the right size for the number of pens, pencils, etc, you generally carry around? Then make your own!

You'll need to think through some initial questions before you start planning your design:

How long is the longest pen, pencil, ruler or other object you might want to carry in it?

How many pens, pencils, etc, do you want to carry about?

If you bunch then all together, and measure round them with a piece of string, what diameter pencil case do you need?

When you've decided on the dimensions of your pencil case, have a think about what shape would be a good idea. You may well decide that a cylinder, cuboid or triangular, hexagonal or octagonal prism would work well.

What does the net of the shape you want look like?

How many separate pieces do you need?

What shape is each piece?

Which sides need to fit together?

Try modelling the net of your pencil case with scrap paper, folding the paper net into shape and sticking it together with sellotape. Does it work? Is it the right size for your pens and pencils?

Once you're happy with your paper prototype, you need to decide what materials you will use for the real thing:

Does it need to be a rigid material or could you use recycled fabric?

Will you need to alter the measurements in your design to use the chosen material?

Do you want the same material for all the pieces, or could the ends be made of something different from the rest?

How will you stick or fasten the pieces together?

How will you do up the pencil case?

Do you want to put a design on any of the pieces before making up the pencil case?

How will you ensure your pencil case stays shut?

Elly has been invited to a fancy dress party. She wants to go as a witch and decides to start with the hat.

Choose one of the hats shown here, or design your own.
What shapes would you need to cut out to make it?
If you're not sure how to make a witch's hat, you could start with a top hat or a fez, and then see how you need to adapt them to make a witch's hat.

You could start by drawing the shapes you think she might need on squared paper, then cut them out to see if they fold into the right sort of hat.
Sellotape will do at this stage to stick your hat together.

When you're happy with your design, try making it with paper, card or fabric.

If you use A4 or A3 paper, try different ways of laying out the pieces you want on the paper.

What is the tallest witch's hat you can make from a sheet of A3 paper?

Here are some questions you might like to consider:
If you wanted to make the tallest hat possible from your A3 paper, would you choose to make a witch's hat, a wizard's hat, a top hat or a fez?
How much difference does having a brim make?
The fez could be modelled as a cylinder or as the frustum of a cone. How does this change the maximum possible height?

Bentwood boxes
Bentwood boxes are on display inside some of thehouses, in front of certain poles and in the exhibitTsimshian Prehistory. Bentwood boxes were made in all sizes, and were used to store food, clothing and many household and ceremonial items. Some were painted and others were elaborately carved, but the majority were left undecorated. Contemporary artists have revived the art of making bentwood boxes. These boxes demonstrate the remarkable carpentry of the West Coast people. The sides were made from a single plank of cedar; it was bevelled or kerfed to allow the four sides to be bent into a box shape. After careful shaping of the plank, it was steamed, bent and sewn together using cedar roots or wooden pegs. The base was prepared so that the edges fitted snugly into the bottom, creating a watertight box. A lid was then added.

This bentwood box was made by the Bella Bella and later acquired (probably through trade) by the Haida. The carved and painted designs show Bear and Whale.

Click on the image of the box to see a Quicktime VR object movie (551K) of the box. This movie can be viewed with any Quicktime player, but is best viewed using Apple's Quicktime VR Player.
