So the idea is that now you have here access to the primitives of the this drawing where you can use primitives to make interesting figures. For example you can manipulate the original line drawing in a process and generate more primitive line drawings, such as these line segments and circles divided into semicircles, and so on. Then you can take these new primitives, which are more primitive than previous primitives, and then make different figures, for example 1, 2, 3 and 4 can combine into the box and 1, 2, 3 and 4 into this box, and 1, 2 and 4 and 5 making this figure and so on.
