IfcClassification - The use of - and / in the classification name.

[shorter]

Apologies if I have posted this already.

 

If I enter XX/YYY as a classification name in the ifc classification pset, I get XX/YYY listed as classification in the IFC when viewed in Solibri or BIM Collab.

 

If I enter XX-YYY, I get nothing.

 

Is this a Vectorworks bug or IFC semantics?

The IFC specification use the CamelCase naming convention for the property set definitions and not the Kebab Case: "… start with the prefix "Pset_" and continue with the English words in CamelCase naming convention" (buildingSMART).

I am talking about the classification fields that are standard in every standard ifc pset. I am not talking about a new pset.

 

for example, the Wall has Cost Index fields that map to the Classification Name and Classification Reference fields in the ifc attributes of the wall, eg Uniclass2015 Ss_25_10.

 

if I enter XX-YYY in place of Uniclass2015 it does not export. XX/YYY does.

 

The issue is that we have been told to use the hyphen and I am not sure the hyphen is a permitted character in that field or if it’s a vw bug.
