I guess that a visual cue which properties are part of the standard and which are custom might help in this situation? For example, different colour of the text/icon or frame around the cards (if that's possible in blender)
I might get thrashed a lot for saying this. I think the primary issue with the IFC format is how the Pset works. The fact that most of the Pset information is not linked to the geometry by default is a problem I feel. (Kind of like the proprietary BIM software where if a geometry/material parameter is changed, the associated geometry and even the other parameter changes) The option of decoupling the Pset with the geometry should not even exist IMHO.
@@spaciotechtonics I think what you're describing already exists. Where it makes sense for an ISO standard to link properties to geometry, they have already done so. For example, Fire rating is naturally not linked to geometry. However parametric layer set thickness (technically not a pset, but still a parametric attribute) is. Same with profile offsets, profile cardinality point (center, top, left, etc). So yes, exactly as you describe if you change a material parameter, the associated geometry is changed and qtos are recalculated. Perhaps we will come across this in a future video (or you can try it now with BlenderBIM Add-on's native parametric modeling abilities, and change properties like height, thickness, profile, etc and see the geometry update correspondingly)

Great idea!
Good idea Daniel, thank you for your sharing it with us!

You should not get trashed out for saying this, all opinions are welcome, so if they are valid good ideas they might get solved :)
@BIMvoice I'm hoping so too. What do you think about this @Dion Moult?

@@DionMoult Great to know that this exists. A video on this would be great if you can.
