Archicad 17 Using building materials with the fill tool

There is a new function with the fill tool which allows you to assign a building material to a fill. I cant think of any reason to have this.
When and what would you use this function for.

The dialog itself gives a hint - see attached. I believe that this is in part to grab the thermal properties of the fill as associated with a Building Material for the "Thermal bridge simulation on ArchiCAD [2D] details" of EcoDesigner STAR. See the video with that name at near the bottom of this page:
http://www.graphisoft.com/archicad/archicad_17/energy_evaluation/

It also captures the intent of a 3D element that has been exploded into 2D elements. See:
http://helpcenter.graphisoft.com/guides/archicad-17-int-reference-guide/documentation/fills/fill-cat...

which says in part:
For construction elements (Wall/Slab/Beam/Column/Roof/Shell/Morph/Mesh): Cut fills are assigned via the Building Material attribute. When such an element is exploded (e.g. in a Detail Drawing), the resulting fill will be in the Cut Fill – Building Material category. A detail Fill in this category retains the Physical properties of the original construction element.

and later:
For example, if you draw a fill as a detail patch, to be used as a cut fill, change its category from “Drafting” to “Cut Fill – Building Material”. This way, this fill will behave like the Building Materials of construction elements in the project,
I'm glad you asked, as I hadn't noticed this feature.

Thanks Karl,
Does this also mean we can add cut fill materials to an existing thermal simulation. Meaning we can model up a quick simulation of a hypothetical wall assembly to test its performance, without creating an actual wall in the model.

Don't know ... never tried the 2D detail bridge thing. Maybe ask in the Sustainable Architecture forum?
