| Item | SPF | XML | Change | Description | IFC2x3 to IFC4 |
|---|---|---|---|---|
| IfcStructuralResultGroup | ||||

| IsLinear | MODIFIED | Type changed from BOOLEAN to IfcBoolean. |
Instances of the entity IfcStructuralResultGroup are used to group results of structural analysis calculations and to capture the connection to the underlying basic load group. The basic functionality for grouping inherited from IfcGroup is used to collect instances from IfcStructuralReaction or its respective subclasses.
HISTORY New entity in IFC2x2.
IFC4 CHANGE WHERE rule added.
| # | Attribute | Type | Cardinality | Description | B |
|---|---|---|---|---|---|
| 6 | TheoryType | IfcAnalysisTheoryTypeEnum | [1:1] | Specifies the analysis theory used to obtain the respective results. | X |
| 7 | ResultForLoadGroup | IfcStructuralLoadGroup | [0:1] | Reference to an instance of IfcStructuralLoadGroup for which this instance represents the result. | X |
| 8 | IsLinear | IfcBoolean | [1:1] | This value allows to easily recognize whether a linear analysis has been applied (allowing the superposition of analysis results). | X |
| ResultGroupFor | IfcStructuralAnalysisModel @HasResults | S[0:1] | Reference to an instance of IfcStructuralAnalysisModel for which this instance captures a result. |
| Rule | Description |
|---|---|
| HasObjectType | The attribute ObjectType shall be given if the analysis theory type is set to USERDEFINED. |

| IfcRoot | |||||
| 1 | GlobalId | IfcGloballyUniqueId | [1:1] | Assignment of a globally unique identifier within the entire software world. | X |
| 2 | OwnerHistory | IfcOwnerHistory | [0:1] |
Assignment of the information about the current ownership of that object, including owning actor, application, local identification and information captured about the recent changes of the object,
NOTE only the last modification in stored - either as addition, deletion or modification. | X |
| 3 | Name | IfcLabel | [0:1] | Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule. | X |
| 4 | Description | IfcText | [0:1] | Optional description, provided for exchanging informative comments. | X |
| IfcObjectDefinition | |||||
| HasAssignments | IfcRelAssigns @RelatedObjects | S[0:?] | Reference to the relationship objects, that assign (by an association relationship) other subtypes of IfcObject to this object instance. Examples are the association to products, processes, controls, resources or groups. | X | |
| Nests | IfcRelNests @RelatedObjects | S[0:1] | References to the decomposition relationship being a nesting. It determines that this object definition is a part within an ordered whole/part decomposition relationship. An object occurrence or type can only be part of a single decomposition (to allow hierarchical strutures only). | ||
| IsNestedBy | IfcRelNests @RelatingObject | S[0:?] | References to the decomposition relationship being a nesting. It determines that this object definition is the whole within an ordered whole/part decomposition relationship. An object or object type can be nested by several other objects (occurrences or types). | X | |
| HasContext | IfcRelDeclares @RelatedDefinitions | S[0:1] | References to the context providing context information such as project unit or representation context. It should only be asserted for the uppermost non-spatial object. | ||
| IsDecomposedBy | IfcRelAggregates @RelatingObject | S[0:?] | References to the decomposition relationship being an aggregation. It determines that this object definition is whole within an unordered whole/part decomposition relationship. An object definitions can be aggregated by several other objects (occurrences or parts). | X | |
| Decomposes | IfcRelAggregates @RelatedObjects | S[0:1] | References to the decomposition relationship being an aggregation. It determines that this object definition is a part within an unordered whole/part decomposition relationship. An object definitions can only be part of a single decomposition (to allow hierarchical strutures only). | X | |
| HasAssociations | IfcRelAssociates @RelatedObjects | S[0:?] | Reference to the relationship objects, that associates external references or other resource definitions to the object.. Examples are the association to library, documentation or classification. | X | |
| IfcObject | |||||
| 5 | ObjectType | - | This attribute is out of scope for this model view definition and shall not be set. | ||
| IsTypedBy | IfcRelDefinesByType @RelatedObjects | S[0:1] | Set of relationships to the object type that provides the type definitions for this object occurrence. The then associated IfcTypeObject, or its subtypes, contains the specific information (or type, or style), that is common to all instances of IfcObject, or its subtypes, referring to the same type. | X | |
| IsDefinedBy | IfcRelDefinesByProperties @RelatedObjects | S[0:?] | Set of relationships to property set definitions attached to this object. Those statically or dynamically defined properties contain alphanumeric information content that further defines the object. | X | |
| IfcGroup | |||||
| IsGroupedBy | IfcRelAssignsToGroup @RelatingGroup | S[0:?] | Reference to the relationship IfcRelAssignsToGroup that assigns the one to many group members to the IfcGroup object. | X | |
| IfcStructuralResultGroup | |||||
| 6 | TheoryType | IfcAnalysisTheoryTypeEnum | [1:1] | Specifies the analysis theory used to obtain the respective results. | X |
| 7 | ResultForLoadGroup | IfcStructuralLoadGroup | [0:1] | Reference to an instance of IfcStructuralLoadGroup for which this instance represents the result. | X |
| 8 | IsLinear | IfcBoolean | [1:1] | This value allows to easily recognize whether a linear analysis has been applied (allowing the superposition of analysis results). | X |
| ResultGroupFor | IfcStructuralAnalysisModel @HasResults | S[0:1] | Reference to an instance of IfcStructuralAnalysisModel for which this instance captures a result. | ||
