get(k: SETTING) Any
get(k: SERIALIZER_SETTING) Any

Return value of the setting named k.

Raises:

RuntimeError – If there is no setting with name k.

static name(k: str) SETTING | SERIALIZER_SETTING
static rname(k: SETTING | SERIALIZER_SETTING) str
set(k: SETTING, v: Any) None
set(k: SERIALIZER_SETTING, v: Any) None

Set value of the setting named k to v.

Raises:

RuntimeError – If there is no setting with name k.

ifcopenshell.geom.main.create_shape(settings: create_shape.settings, inst: ifcopenshell.entity_instance.entity_instance, repr: ifcopenshell.entity_instance.entity_instance | None = None, geometry_library: GEOMETRY_LIBRARY = 'opencascade') ShapeType | ShapeElementType | ifcopenshell.ifcopenshell_wrapper.Transformation | ifcopenshell.geom.occ_utils.shape_tuple | OCC.Core.TopoDS.TopoDS_Shape

Return a geometric representation from STEP-based IFCREPRESENTATIONSHAPE or Return an OpenCASCADE BRep if settings.USE_PYTHON_OPENCASCADE == True

Note that in Python, you must store a reference to the element returned by this function to prevent garbage collection when you access its children. See #1124.

Raises:

RuntimeError – If failed to process shape. You can turn detailed logging to get more details.

Returns:

  • inst is IfcProduct and repr provided / None -> ShapeElementType

  • inst is IfcRepresentation and repr is None -> ShapeType

  • inst is IfcRepresentationItem and repr is None -> ShapeType

  • inst is IfcProfileDef and repr is None -> ShapeType

  • inst is IfcPlacement / IfcObjectPlacement -> Transformation

  • inst is IfcTypeProduct and repr is None -> None

  • inst is IfcTypeProduct and repr is provided -> RuntimeError

(for IfcTypeProducts provide just IfcRepresentation as inst).

If ‘use-python-opencascade’ is enabled in settings then

  • instead of ShapeElementType it returns shape_tuple,

  • instead of ShapeType it returns TopoDS.TopoDS_Shape.

Example:

settings = ifcopenshell.geom.settings()
settings.set(settings.USE_PYTHON_OPENCASCADE, True)

ifc_file = ifcopenshell.open(file_path)
products = ifc_file.by_type("IfcProduct")

for i, product in enumerate(products):
    if product.Representation is not None:
        try:
            created_shape = geom.create_shape(settings, inst=product)
            shape = created_shape.geometry # see #1124
            shape_gpXYZ = shape.Location().Transformation().TranslationPart() # These are methods of the TopoDS_Shape class from pythonOCC
            print(shape_gpXYZ.X(), shape_gpXYZ.Y(), shape_gpXYZ.Z()) # These are methods of the gpXYZ class from pythonOCC
        except:
            print("Shape creation failed")
