System info:

- Windows 10
- python 3.12.9
- compas 2.10.0
- compas-ifc 1.5.0
- compas-viewer 1.4.0
- compas\_occ 1.2.1

I am testing compas for the first time, based on the tutorials found here: [tutorials/IFC/README.md at main · compas-dev/tutorials · GitHub](https://github.com/compas-dev/tutorials/blob/main/IFC/README.md)

This is my script:

```auto
path = 'model.ifc'
model = Model(path)

spaces = model.get_entities_by_type("IfcSpace")

viewer = Viewer(width=1200, height=600)

for entity in spaces:
	viewer.add(entity.body_with_opening, name=entity.name)

viewer.show()

```

I get the following AttributeError: ‘Viewer’ object has no attribute ‘add’

Could anyone tell me what i am doing wrong? Thank You in advance.

Hey @Daiva

Could you try `viewer.scene.add(...)` instead?  
I suspect the example code my be a little outdated.

Please let me know if that does it.

Chen
