As part of a Geometry & Art ICT unit, we use the free online 3D design application, Tinkercad. This is particularly useful for helping students to understand that all objects they see on a daily basis are made up of geometric shapes. Tinkercad enables students to resize and merge various geometric shapes to design both familiar and new objects alike.
The Anchor Design Activity
The activity below, which gets students designing an anchor, is a good introduction to Tinkercad.
As an extension, ask the students if they can redesign the anchor to include four legs instead of just two.
If you have access to a 3D Printer, the designs created in Tinkercad can be 3D printed. To do this, first click the design menu, then select ‘Download for 3D printing’. A warning window will then appear on the screen. Click the option ‘.SLT’. This is the 3D file type that most 3D printer brands recognise. Once downloaded, you can open the 3D file on your 3D printer’s software.
