#cube

A cube is a three-dimensional shape with six square faces, twelve edges, and eight vertices. It is one of the most familiar geometric solids and is a special type of rectangular prism where all sides are of equal length. A cube has a high degree of symmetry. Angles between its faces are right angles. It is often referred to as a “regular hexahedron”. Also cube is one of the Platonic solids, known for its perfect symmetry and simplicity. Nevertheless, the…

In the Digital Fabrication course, we are in the middle of a sea, full of technical details, and students need motivation. This is why I felt I should do something simple and educational but funny at the same time; a “kissing the cube” exercise. The planned exercise was about programming the robot to touch every facet of a cube without colliding with it. Of course, we couldn’t manage to kiss all the facets due to the limitation of the robot’s…

The tetrahedron is a popular platonic solid for designers. We’ve explained how to draw them using equilateral triangles here before. Recently I’ve found (sorry, lost the web address) a much quicker way of modeling a Tetrahedron using a cube. It’s very simple, just connecting the three opposite corners of the cube automatically makes them equal, resulting in the four equal faces. Of course this time you’ll have to calculate the actual edge length, but if you use the “box diagonal”…
