wrong units in files lead to wrong volumes

[louistrue]

volume is wrong, probably because units are defined wrong in ifc:

{"id": 279, "type": "IfcWallStandardCase", "properties": {"loadBearing": null, "isExternal": null}, "object_type": null, "volume": {"gross": 0.00664241232415517}, "area": {"gross": 0.017952465740960002}, "dimensions": {"length": 22.440582176200003, "width": 0.37, "height": 0.8}, "materials": ["Copper pipes length 5 m 42x1,5 mm"], "material_volumes": {"Copper pipes length 5 m 42x1,5 mm": {"volume": 0.00664241232415517, "fraction": 1.0}}}

should be "gross": 6.642412324 not "volume": {"gross": 0.00664241232415517}
