Handling Annotations in IFC2x3 (SPS007)

[acdeepika]

I am validating an IFC file with the IFC2x3 schema in SPS007.
The file contains IfcAnnotation objects related to a spatial structure using IfcRelContainedInSpatialStructure.

While this is schema-valid in IFC2x3, SPS007 reports a spatial containment error for these annotations.

According to the Coordination View 2.0 Entity List (CoordinationView_V2-0_EntityList_IFC2x3_Version-1-6_Final.pdf), on page 13, IfcAnnotation is marked red (0) in all columns, meaning it is out of scope for Architecture, Building Services, and Structural disciplines in CV2.0.

I understand this is why the validator flags the error. However, the current validation error can be misleading; it appears to indicate an issue with the containment itself, when in fact the entity type is simply not part of the CV2.0 MVD.

Attached is the file with the above-mentioned issue.

Could you please help us with the following questions

1. Is it possible to move such cases to the N/A section instead of reporting them as errors?
2. Could the error be updated to indicate that the entity is "not part of CV2.0 scope" rather than a generic spatial containment error?
3. Is there any recommended workaround we can use to avoid this error while still maintaining schema correctness?

This is an error in the Validation Service logic and not related to the CV2.0 MVD. SPS007 checks for an IfcRelContainedInSpatialStructure relationship to IfcAnnotation from IfcSpatialElement. IfcBuildingStorey does not inherit from IfcSpatialElement, which is why the SPS007 error is being raised. The relating entity superclass should actually be IfcSpatialStructureElement, not IfcSpatialElement. Your sample model (thanks for providing! 😁) passes when the .feature file is corrected accordingly.

Our next scheduled update for the Validation Service is Monday 25 August. We will include this fix in the upcoming release. You can stay notified on new releases by subscribing to this thread on the buildingSMART forums.
