As shown in the below image - what IFC class do the gold elements belong to? The bolts belong to
PredefinedType = BOLT, but what about the metal plates and stiffeners?
I would imagine it is
IfcPlate, as shown here but there are some conflicting descriptions. The first is that the page says:
NOTE Definition according to ISO 6707-1: thin, rigid, flat, metal product, of a thickness greater than that of a sheet.
So this seems correct, it is a thin, rigid, flat, metal product, with a thickness greater than a sheet. However. the
IfcPlateTypeEnum only gives 4 enums: it is obviously not a
CURTAIN_PANEL and the name
SHEET implies a thin sheet, kind of like what I’d usually expect for a
PredefinedType=CLADDING for thin metal cladding sheets. This leaves me with
USERDEFINED, which I’d rather avoid since this is a very common element and
NOTDEFINED which again I’d rather avoid if there is a better choice.
Perhaps it falls under
IfcDiscreteAccessory, as it is an “accessory”, perhaps, although it only has
SHOE, of which this is none of them.
