What Are Subassemblies Made of?
Subassemblies are made up of three fundamental components: points, links, and
shapes. A point is self-explanatory, a link is a line that is drawn between two
points, and a shape is the result of three or more links forming a closed shape, as
shown in the following diagram. Each point, link, and shape in a subassembly has
at least one code. These codes are used to identify the purpose of a component
and control its style, behavior, and relationship to other parts of the design.
A collection of styles that apply to multiple codes is called a
code set style
