2. Hexagonal Prisms - the Development
A development is a flat template of a 3D shape that when folded up in the correct way makes the actual shape of the 3D object.
Developments are particularly useful when modelling new design ideas or to prepare for folding shapes in sheet metal.

3. Hexagonal Prisms - the Development
Here the development of the sides will be drawn. This does not include the top and bottom of the prism.
Project the height of the prism across the page.

4. Hexagonal Prisms - the Development
Now, using a compass, step out the lengths of each side onto these lines.
Draw vertical lines at each of these points.

5. Hexagonal Prisms - the Development6 1
To make things easier we number each of the corners of the hexagon. 5 2
Do this as shown on the Plan, Elevation and development. 4 3
Plan 1 2 3 4 5 6 1
A development always starts and ends with the same numbered corner. When it folds up these should meet.
Here one number is above the other. This is because corner number 3 is in front of corner 1. 5 4 3 2

Project the cuts across onto the development marking the appropriate corners as you go. 5 2 4 3

Now join your dots up to complete the development. 5 2
As the hexagonal prism has no curves, use a straight edge to join the dots. 4 3
