IFC tutorial scripts broken with compas_ifc 1.7.0 and compas_viewer 2.x

Comece lendo viewer.py, spatial_tree.py e attribute_tree.py e, em seguida, compare seus imports, chamadas a viewer, configuração do Treeform e tratamento da geometria com as APIs atuais listadas. Atualize os três scripts para compas_ifc 1.7.0 e compas_viewer 2.x, incluindo a escala de unidades IFC, e confirme que os tutoriais são executados com o ambiente especificado.

Environment

• OS: Windows 11
• Python: 3.12
• compas_ifc: 1.7.0
• compas_viewer: 2.0.2
• ifcopenshell: 0.8.5

Problem

The tutorial scripts viewer.py, spatial_tree.py, and attribute_tree.py
use outdated APIs that no longer work with current package versions.

Fixes required

viewer.py / spatial_tree.py / attribute_tree.py

1. body_with_opening no longer exists

# OLD
viewer.add(entity.body_with_opening, name=entity.name)
# NEW
geom = entity.geometry
if geom:
    viewer.scene.add(geom, name=entity.name)

2. viewer.add() no longer exists → use viewer.scene.add()

3. from compas_viewer.layout import Treeform no longer exists

# OLD
from compas_viewer.layout import Treeform
# NEW
from compas_viewer.components.treeform import Treeform

4. from compas_ifc.entities import Entity no longer exists

# OLD
from compas_ifc.entities import Entity
# NEW
from compas_ifc.entities.base import Base as Entity

5. viewer.layout.sidedock.add_element() no longer exists

# OLD
viewer.layout.sidedock.add_element(Treeform(...))
# NEW
treeform = Treeform(...)
treeform.update()  # required to populate the widget
viewer.ui.sidedock.add(treeform)

6. Treeform columns API changed

# OLD
Treeform(tree, {"Name": ".name", "Value": ".attributes['value']"})
# NEW
Treeform(tree, columns={"Name": lambda n: n.name, 
                         "Value": lambda n: n.attributes.get("value", "")})

7. Scale needed for correct geometry size (IFC units are in mm)

from compas.geometry import Scale
S = Scale.from_factors([0.001, 0.001, 0.001])
geom.transform(S)
