The important spatial skills that you build from a basic understanding of shape nets can therefore develop further into other more challenging design applications. For more on this, see our page on polar, cylindrical and spherical coordinate systems.īeing able to understand how a three-dimensional shape is made up of two-dimensional components is not only a useful skill if you need to construct a box, but is also vitally important in any aspect of 3D design.Įngineers and designers use complex and powerful computer aided design (CAD) packages to help design everything from flat-packed furniture to the world’s largest cruise ships. This is also an approximation, but it incorporates a distorted view of the surface of the globe that allows distances to be measured accurately on a flat map. Even if there were 100 segments in the net above, it would still be an approximation.Ĭartographers eventually overcame this problem by making maps based on a cylinder, called a projection. It is therefore impossible to make a completely accurate 2D net of a 3D shape with double curvature. Looking again at your pieces of orange skin, they not only curve top to bottom, but they curve side to side as well, unlike the page, which can only curve in one direction. No matter how many segments, each one will still have a flat surface. However, there is a flaw with this approach. If you were to line them up, then they would look similar to the net of a sphere. When you have eaten the flesh, you are left with the pieces of skin.
