Although the main application for the GraphGrid is often a regular rectangular grid, there are other applications in which one or more rubber bands can be placed diagonally, in addition to the regular horizontal and vertical axes.
07.1 – 3D coordinate system
By adding an extra rubber band as a third axis, which passes diagonally through the intersection of the other two axes (the origin) at an angle between 30 and 45 degrees, a 3D coordinate system is created. Here you can create drawings of three-dimensional bodies.
07.2 – Shape outline
You can use the rubber bands to compose the outlines of 3D bodies as well, such as a cube or pyramid. Again, you can distinguish between different (visible or invisible) line segments with higher- and lower-running rubber bands. The indents at all four outher sides of the GraphGrid allow you to position the rubber bands at any position and angle.
