Python Get Building Materials

Hi all,

I'm tring to do my first Python programm running in Archicad.

Everything stops at the beginning with this command:

building_materials = acc.GetBuildingMaterials()

it aswer "AttributeError: 'Commands' object has no attribute 'GetBuildingMaterials'"

I need it to retrive the material index with the floowing commands:

BUILDING_MATERIAL_NAME = "Estrich + Parkett 15 cm"

for bm in building_materials:

if bm.name == BUILDING_MATERIAL_NAME:

bm_index = bm.index

break

Thank you in advance

Hi Davide, welcome to the forum!

There is no command "GetBuildingMaterials", only "GetBuildingMaterialAttributes". Maybe that solves this already.

Let me also recommend you Tapir; which is not a replacement but enhances the capabilities of the Python connection drastically.
