Agreed, architects usually classify walls into things like: - partitions - masonry (block walls, brick walls) - exterior walls (i know, there's an overlap with IsExternal) - core walls -...

Yeah this is a great idea but I don't know the best way to implement this (permanent ratings? flagging mechanism? anonymous vs named reports?) I also reckon we can (and...

Yes - that blog post is outdated and at the time it was a theoretical possibility but as mentioned it's basically a really bad idea to mix any sort of...

I should probably mention that Scale doesn't exist on IfcRigidOperation. This makes the behaviour inconsistent and ambiguous as to how to handle IfcLengthMeasure.

@pjanck why is the Scale attribute omitted for IfcRigidOperation? How do you handle mixing of unit types between object placements which are IfcLengthMeasure + IfcPlaneAngleMeasure = ?

Ping @Andrej730 because for BBIM we typically use the IFC definitions not the XML and we noticed that the XML was missing data that the IFC contained. I vaguely recall...

It's probably something to fix in the XML then, as I think for user defined pset templates (i.e. stored in IFC propertysettemplate entities) you can have non IfcLabel enums and...

100% agree. I only bring this up because people around the world are delivering "COBie" (mostly contractually) and nobody is really asking these questions :(

Hold on, what happens to timeseries? For the other usecases, I think it makes sense to deprecate and they seem pretty straightforward, but for timeseries it breaks a pretty fundamental...

Agreed, this is a larger issue which applies to (almost?) all enums.
