Nice, the only thing to think about is Zones and Systems maybe, which are subtypes of groups and use the same relationship. For end-users I can imagine it is confusing that Zones and Systems count as groups.

Seeing we have a SYS000 planned as well, I do think we should exclude subtypes and only specifically have IfcGroup trigger activation in this rule.

We have GRP001 already active and explicitly includes systems (and zones as a subtype of systems) in the feature description. SYS000 is indeed in the backlog but SYS001 is disabled. My preference would be to leave this rule as-is, especially since the feature description references a concept template that includes systems. We could still move forward with SYS000 and scope it to IfcSystem and subtypes. A model correctly utilizing those entities would then activate the GRP and SYS functional parts, which IMHO makes sense. It seems logical that a zone is a group of spaces and a system is a group of things like electrical circuits or other distribution systems like stormwater drainage pipes, inlet, and manholes. |

Per JIRA discussion: Merge GRP000 as-is. SYS000 deleted from catalog as SYS is not in the final list of functional parts. |
