List of datatypes with Enum types used by attributes about ids

[aothms]

This was not done in 4.3.2 for whatever reason.

It's not heavily advertised / published, but it does exist. Just fyi.

#4916=IFCPROPERTYENUMERATION('PEnum_TankAccessType',(IFCLABEL('LOOSECOVER'),IFCLABEL('MANHOLE'),IFCLABEL('NONE'),IFCLABEL('SECUREDCOVER'),IFCLABEL('SECUREDCOVERWITHMANHOLE'),IFCLABEL('OTHER'),IFCLABEL('NOTKNOWN'),IFCLABEL('UNSET')),$);

I understand... the underlying type of enums is an actual IFCLABEL in the IFC file... while the 'template' is coming from the enumeration type.
I will see to improve the tool and the documentation appropriately.

The underlying type of property enums is an IfcLabel. This is not true for enums. Enums are EXPRESS ENUMERATION types. Those two are not to be confused. Property enums were serialized as a computer interpretable listing in .ifc and .ifcxml as declared in a project library e. g.:

#4370= IFCPROPERTYENUMERATION('PEnum_TankAccessType',(IFCLABEL('NONE'),IFCLABEL('LOOSECOVER'),IFCLABEL('MANHOLE'),IFCLABEL('SECUREDCOVER'),IFCLABEL('SECUREDCOVERWITHMANHOLE'),IFCLABEL('OTHER'),IFCLABEL('NOTKNOWN'),IFCLABEL('UNSET')),$);

This was not done in 4.3.2 for whatever reason.

Enums (not property) are part of the EXPRESS schema. They are not IfcLabel in an ifc file and also not parsed as such. Enumerations are a set of named numerical values. This is also something that makes 4.3.2 backwards incompatible since the order of the constants was changed. IfcLabel is enclosed in single quotes and enums in dots ('' vs ..).

Oh, my we could have used this last month! 😄

I think most BBIM users also heavily use custom pset template definitions with property enumeration. So it's pretty common here :)

would be nice to add to IDS Audit tool? @CBenghi
