Part occurrenceAn occurrence with a Part component is a

Assembly occurrenceAn occurrence with no Part component, and having other occurrences as children, is called an 
Assembly occurrence
, or 
Assembly
. An Assembly is basically a node used to store other nodes, like a group or a folder. For example, the function Merge Parts By Assemblies finds all the Assembly occurrences in the Tree and merges their Part occurrences children as one resulting Part occurrence.		Assembly
Assembly icon
Empty occurrenceAn occurrence containing no geometry (no Part component or a Part component containing no geometry), no light (no Light component) and having no children, is called an empty occurrence. For example, the function Delete Empty Occurrences finds all the Empty occurrences in the Tree and deletes them.Empty occurrence

About Icon color

Depending on its status, an occurrence's icon will be displayed in the Product Structure with a dedicated color:
  • A cyan icon corresponds to an occurrence owning a prototype, and not expanded in the tree.
  • An orange icon corresponds to an occurrence having children, and expanded in the tree.
  • A gray icon corresponds to an occurrence not owning a prototype, and not expanded in the tree.
