Your teacher will help you set up an account. You should use the scribble tool in TinkerCAD to draw a flat shape that will be laser cut. Insert images of your TinkerCAD work onto your digital portfolio.

Blocks and hand drawn shapes can be pieced together just like LEGO to build a bigger shape.
You can design and build any shape in any colour.
You have a 360 degree view from all sides and all angles to check every side of your design.
You can create layers and levels which allow you to stack shapes on top of shapes.
CAD Computer Aided Design / CAM Computer Aided Manufacture
CAD Computer Aided Design / CAM Computer Aided Manufacture
Computer Aided Design (CAD) involves designing using a computer and specialist software. It can be used to virtually model ideas in 3D. This is especially useful as design work can be viewed from many angles before being manufactured.
When you link the computer to a machine this is called Computer Aided Manufacture (CAM). The machine can process the design information and accurately machine out your work. This will allow you to produce a high quality puzzle design.
Some of the many advantages of CAD / CAM are shown below.
Accuracy
Easy to make modifications (changes)
Sharing ideas (across the Internet / e-mail)
More than one person can work on a design (big companies and complex projects)
Speed
3D models can be virtually prototyped to show a client
Production is very quick
Machinery can work continuously or through the night if necessary
Production can be repeated time and time again
CAD is the the first part of the manufacture process.
You are going to use TinkerCAD to model your maze design in 3D. It can then be laser cut from the 3D file.
Join your class using the code or the button below.
Make sure you insert photo’s of your 3D model onto you digital portfolio.

Follow your teachers demonstration and instructions on how to draw basic shapes.
Your teacher will cut out your 3D CAD design on the laser cutter.
Step 3. Export as SVG + AirDrop
Step 3. Export as SVG + AirDrop
Now that you have finished your design, you need to export it as a SVG file.
You need to design the following
You need to design the following
3 different shapes
3 shapes of 3 different thicknesses
3 new colours, a different colour for each shape
Take a screenshot of your 3D model OR click Send To > Download Picture
You need to do the following
You need to do the following
Select the individual shape you want to export. A blue box with highlight the shape
Click export from the top right menu
Choose SVG
Click download
Open the Files app on your iPad and find the downloaded SVG file
AirDrop the SVG file to your teacher
You will have 3 shapes on TinkerCad so you must follow this step 3 times for each file

Step 4. Handmade design
Step 4. Handmade design
After copying your designs on to your piece of wood, cut out the 3 shapes with a coping saw.
Follow the cutting techniques demonstrated by your teacher to avoid splitting or ripping the wood and to avoid damage to the saw blade.
Step 5. Finishing
Step 5. Finishing
Once you have cut your 3 shapes and are happy with the designs, you will need to sand the edges with sandpaper to remove any splinters or rough sides.
#4 sandpaper and #0 will be fine to achieve a smooth finish.
You should also use the sandpaper to remove any pencil lines on the surface of the wood so that it looks nice and clean.
Step 6. Evaluation poster
Step 6. Evaluation poster
Create a poster on Google Slides on all your designs and models. You should include screenshots and your own photos.
On your poster you should make comparisons of the following:
On your poster you should make comparisons of the following:
The 3D CAD design
Your own paper template drawing
Your laser cut model
Your hand cut model
Be descriptive when writing about your work and explaining whats better, faster, easier or more fun. Also explain and discuss the benefits of the different processes.

Follow your Tinkercad design but draw it on cardboard and cut it out.
You will then compare your design you cut out from cardboard with your other CAD design that your teacher cut out for you on the laser cutter.
You need to do the following
You need to do the following
Copy your 3 Tinkercad shapes and draw them onto cardboard
Cut out your shapes as neatly as possible
Stack and position your 3 shapes in the same was as your Tinkercad design
Take a photo of your cardboard model
Add and compare your cardboard model photo and Tinkercad photos side by side on a Google Slide - example of outcome below.
Class example
Class example
All shapes, sizes and designs are a close match but if you look carefully they do not match perfectly.
Student example
Student example
Most shapes match closely but the cardboard square isn't a perfect square that matches the Tinkercad design.
Student example
Student example
All shapes, sizes and designs are a close match but we can still spot differences.
Student example
Student example
The shapes look similar but do not match, the blob is a different shape and the star has been positioned differently in a different place.
