It contains concrete AsBuiltItems with serial numbers, lot numbers, work order information, actual quantities, installation dates, and quality status. | Key attributes: as_built_status, build_date, configuration_snapshot, editing_state (+12) · Relations: has_root_as_built_item->AsBuiltItem, responsible_person->PersonOrRole | ToolObject | 16 | 2 | 0 | 2 |
| IdentifiedThing | AssemblyTree | Manufacturing-oriented assembly structure. An AssemblyTree describes how a product is organized for manufacturing or assembly. It may represent an mBOM-like structure, a manufacturing view of the product, a plant-specific assembly structure, or a structure prepared for downstream process planning and execution. | Key attributes: build_strategy, configuration_spec, editing_state, effectivity (+10) · Relations: has_root_assembly_tree_item->AssemblyTreeItem, responsible_person->PersonOrRole | ToolObject | 14 | 2 | 0 | 2 |
| IdentifiedThing | AssemblyTreeItem | Assembly-structure item representing the manufacturing or assembly usage of a part definition. It describes how a part-like item is needed, grouped, consumed, installed, assembled, or produced from the manufacturing point of view. It can point back to the ProductTreeItem it is a manufacturing view of. | Key attributes: default_unit, effectivity, find_number, line_number (+14) · Relations: has_assembly_tree_child->AssemblyTreeItem, is_manufacturing_view_of->ProductTreeItem, uses_part_definition->WindchillPart, responsible_person->PersonOrRole | PartItem | 18 | 4 | 0 | 3 |
| IdentifiedThing | IdentifiedThing | A thing with a stable semantic identifier. | Subclasses: PersonOrRole, SemanticItem, ToolObject · Key attributes: description, id, name | | 3 | 0 | 3 | 0 |
| IdentifiedThing | PartItem | Abstract superclass for all part-like Windchill concepts in this model. A PartItem clusters common attributes shared by managed parts, product tree items, assembly tree items, and as-built items. These common attributes include identity, name, description, version, lifecycle state, editing state, source-system information, and responsibility. Concrete subclasses specialize this common level for definition, product-structure usage, manufacturing-structure usage, or physical realization. | Subclasses: AsBuiltItem, AssemblyTreeItem, ProductTreeItem, WindchillPart · Key attributes: editing_state, item_version, lifecycle_state, description (+5) · Relations: responsible_person->PersonOrRole | ToolObject | 9 | 1 | 4 | 2 |
| IdentifiedThing | PersonOrRole | A person, role, actor, or organizational responsibility. | Key attributes: email, description, id, name | IdentifiedThing | 4 | 0 | 0 | 1 |
| IdentifiedThing | ProductTree | Engineering-oriented product structure. A ProductTree defines the product from the product-definition or engineering point of view. It contains a root ProductTreeItem and may represent an eBOM-like structure, a configured product structure, or another engineering decomposition interpreted from Windchill. | Key attributes: configuration_spec, editing_state, effectivity, lifecycle_state (+7) · Relations: has_root_product_tree_item->ProductTreeItem, responsible_person->PersonOrRole | ToolObject | 11 | 2 | 0 | 2 |
| IdentifiedThing | ProductTreeItem | Product-structure item representing the usage of a part definition inside an engineering or product tree. A ProductTreeItem is part-like because it has name, description, version, lifecycle state, and editing state, but it is more specific than the reusable WindchillPart: it represents the part as used at a particular position in a particular product structure. | Key attributes: default_unit, effectivity, find_number, line_number (+13) · Relations: has_product_tree_child->ProductTreeItem, uses_part_definition->WindchillPart, responsible_person->PersonOrRole | PartItem | 17 | 3 | 0 | 3 |
| IdentifiedThing | SAPMaterial | Material represented in SAP. | Key attributes: material_number, material_type, sap_plant, description (+5) · Relations: responsible_person->PersonOrRole | ToolObject | 9 | 1 | 0 | 2 |
| IdentifiedThing | SemanticItem | Tool-independent semantic item that may be represented by several objects in different enterprise systems. | Key attributes: represented_by, description, id, name · Relations: classification_assignments->ClassificationAssignment, responsible_person->PersonOrRole | IdentifiedThing | 4 | 2 | 0 | 1 |
| IdentifiedThing | ThreeDXEngineeringItem | Engineering item represented in 3DEXPERIENCE. | Key attributes: maturity_state, revision, three_dx_type, description (+5) · Relations: responsible_person->PersonOrRole | ToolObject | 9 | 1 | 0 | 2 |
| IdentifiedThing | ToolObject | A representation of an object in a specific authoring or enterprise tool. | Subclasses: AsBuiltTree, AssemblyTree, PartItem, ProductTree, SAPMaterial, ThreeDXEngineeringItem · Key attributes: external_id, source_system, tool_name, description (+2) · Relations: responsible_person->PersonOrRole | IdentifiedThing | 6 | 1 | 6 | 1 |
| IdentifiedThing | WindchillPart | Managed Windchill part definition. A WindchillPart represents the reusable product or part object managed in Windchill, for example a component, assembly, purchased part, manufactured part, or product-level item. It is the part definition that may be used by product tree items, assembly tree items, and realized by as-built items. | Key attributes: default_unit, make_buy, windchill_container, windchill_number (+11) · Relations: responsible_person->PersonOrRole | PartItem | 15 | 1 | 0 | 3 |
