Hi,

I don't know if it's the good practice to continu a topic or create a new one but I propose to complete this topic by asking an advice.

I don't understand how to use the USERDEFINED and NOTDEFINED construction type.

In the case the Ifc Standard don't give me what I search can I invent a construction type ?

For example I have a eye rinse. I think this is an IfcSanitaryTerminal IFC Class.

In BlenderBIM ifc searcher I have this choices :

IfcSanitaryTerminal BATH, BIDET, CISTERN, SHOWER, SINK, SANITARYFOUNTAIN, TOILETPAN, URINAL, WASHHANDBASIN, WCSEAT, USERDEFINED, NOTDEFINED

What is the best practice ? Creating an EYERINSE type, choose the USERDEFINED, choose the NOTDEFINED or let a blank case ?

Hey, in your case of an eye rinse I would use IfcSanitaryTerminal set to "SANITARYFOUNTAIN" and further add an extra PSet Pset_SanitaryTerminalTypeSanitaryFountain with the "FountainType" field set to "EYEWASH" -> see PEnum_FountainType.

In IFC there is also practice to set ObjectType if PredefinedType = USERDEFNIED

Hi Doia, I didn't expect there was a "third" layer IFC ! Thank you for the tip, i have to ckeck this.

Hi Andrej, thanks I understand now that I can use the ifclabel to name an USERDEFINED element.
