Mr Leary

Vigorously test the model created to confirm if it meets all the needs, criteria and specifications of the original design, including discussing with possible clients.Note anything which could be improved and return to the design phase to improve.

Use 2D and 3D computer aided design as well as models e.g. cardboard, foam modelling, clay. to build a model of the design.

The Design Process: Iterative Design.

The iterative process is an approach to continuously improving a concept, design, or product. Creators produce a prototype, test it, tweak it, and repeat the cycle with the goal of getting closer to the solution.

Consider a problem, research the problem and design a possible solution to this problem using:- Spider diagrams- Discussion- Drawings

Export - .STL file

Create G-Code file

Ultimaker Cura

See seperate hand out for setting up and using Cura.

Advanced design skills in Tinkercad:

  • Creating complex design patterns using duplicate and repeat.
  • Creating 'tools' to cut out more complicated or curved shapes.
  • Accurate locating of holes or other pieces.
  • Articulated designs

Before you can begin with these skills you must be familiar with the following tools:- Duplicate and repeat- Group and ungroup- Holes and solids- Align

The Design Process



Following an Iterative design process helps us to constantly improve our designs.



What could you use C.A.D and C.A.M. for?


Use testing and evaluation techniques to consider how successful your design has been

Test and Evaluate

Use Tinkercad and 3D design to design an item.

What is Computer Aided Design and Computer Aided Manufacture?(or C.A.D. & C.A.M.)

Computer aided design (CAD) and Computer Aided Manufacture (CAM) is the use of computer software to design new products in both 2D and 3D and then produce them using Computer aided machinery.

Why is Cad/cam essential in design?

  • Log in to Tinkercad.
  • Go to 'Activities'.
  • Click on 'Learning Tinkercad (CAD)'
  • Choose the tutorials your teacher asks you to do.


We will use Tinkercad Tutorials to learn the basics of designing with 3D software.

By following the tutorials you will be designing your own items in Tinkercad in no time!
