Search IFC4.3 entities by name or description keyword.

Returns matching entities with their name, layer, schema, and short definition. Supports partial name matching and description text search.

Args:

• query (string): Search keyword (e.g. "Wall", "beam", "spatial", "opening")

• limit (number): Max results, 1-100 (default: 20)

• offset (number): Pagination offset (default: 0)

• response_format ('markdown' | 'json'): Output format (default: 'markdown')

Returns: List of matching entities with name, layer, schema, and short definition.

Examples:

• "Wall" → IfcWall, IfcWallType, IfcWallStandardCase, ...

• "spatial" → IfcSpatialElement, IfcSpatialStructureElement, ...

• "beam" → IfcBeam, IfcBeamType, IfcBeamStandardCase, ...

Get the complete definition of an IFC4.3 entity including attributes, inheritance, WHERE rules, and description.

Returns the entity's structural definition from the EXPRESS schema merged with the Markdown documentation.

Args:

• name (string): IFC entity name (e.g. "IfcWall", "IfcBeam", "IfcProject")

• include_inherited (boolean): Include attributes inherited from supertypes (default: true)

• include_inverse (boolean): Include inverse relationship attributes (default: false)

• include_description (boolean): Include Markdown description text (default: true)

• response_format ('markdown' | 'json'): Output format (default: 'markdown')

Returns: Entity definition with attributes, types, inheritance chain, WHERE rules, and description.

Examples:

• "IfcWall" → Wall entity with PredefinedType, supertype chain to IfcRoot

• "IfcProject" → Project entity with global context attributes

Get the inheritance hierarchy of an IFC4.3 entity.

Shows ancestor chain (supertypes up to IfcRoot) and/or descendant tree (subtypes).

Args:

• name (string): IFC entity name (e.g. "IfcRoot", "IfcProduct", "IfcWall")

• direction ('descendants' | 'ancestors' | 'both'): Which direction to show (default: 'both')

• depth (number): Max depth for descendant tree, 1-10 (default: 3)

• response_format ('markdown' | 'json'): Output format (default: 'markdown')

Returns: Inheritance hierarchy showing ancestors and/or descendants.

Examples:

• "IfcRoot" with direction="descendants" → full class hierarchy tree

• "IfcWall" with direction="ancestors" → IfcWall → IfcBuiltElement → ... → IfcRoot

• "IfcProduct" with direction="both" → both ancestor chain and subtype tree

Get or search IFC4.3 PropertySet definitions.

In 'get' mode, retrieves the full definition of a named PropertySet including individual property names, data types, and IFC type mappings. In 'search' mode, searches PropertySets by keyword.

Args:

• name (string): PropertySet name (e.g. "Pset_WallCommon") or search keyword

• mode ('get' | 'search'): Lookup mode (default: 'get')

• limit (number): Max results for search mode (default: 20)

• offset (number): Pagination offset for search mode (default: 0)

• response_format ('markdown' | 'json'): Output format (default: 'markdown')

Returns: PropertySet definition with properties (name, dataType, ifcType, valueKind) and descriptions.

Examples:

• name="Pset_WallCommon", mode="get" → Full PropertySet definition with 10 properties

• name="Wall", mode="search" → All PropertySets related to walls

• name="thermal", mode="search" → PropertySets with thermal properties
