Hello,
I’v noticed that some property names has change from IFC2x3 to IFC4 even their definition is the same and even the property set is the same.
Also, I did not see in the change lock any comments about that change.
For example:
EnvironmenalClass has changed to ExposureClass
ContructionType has changed to ConstructionMethod
Anyone knows the reason for this changes, and if they are registrated in same document so I can modify easely my property mapping method from my bim autohirng tool?
I think, if buildingSMART moved to using version control to manage the schema, that this will no longer be a problem.
In a pinch, you could take the computer interpretable Psets from both IFC2X3 and IFC4 and diff them.
