Hi @bimgeek,
sounds good. thanks for the update.

Hi @ks-cph,

Thanks for the report!
In Archicad, Component Schedules are created based on Building Materials used in construction elements. For example, a composite wall will have components based on the skins/layers of the Composite attribute, a profiled beam will have components based on the Building Materials attached to the polygon parts of the Profile.
This functionality is also available for GDL-based elements (Object, Door, Windows, etc.): you need to define the Building Material in the GDL script and all geometries from subsequent GDL script will belong to that component. E.g. you can model the window frame and glass in two separate components.
However, for most of the library elements in the Archicad Library shipped with Archicad this is not developed. They do not define building materials at all, so the whole library element will belong to one component. This is why we export only one component to Speckle. (I realized that in the Archicad Component Schedule you cannot list the one and only component for windows, possibly because there is no real material behind. So it might be a bug in the Speckle Connector, we should just skip the component in these cases, to be similar to Archicad's Component Schedule).
Regarding the displayValue, you are right you can see some material information, but this is based on the Surface attribute and not on Building Materials.
If you have any questions, please let us know!

Regards,
József
