The class StructuralMember is the base class of all structural items. This class is not abstract and could be used to define any generic structural element, but it is recommended to use any defined subclass if available. StructuralMember instances must be contained in PhysicalModels.
Classification of StructuralMember instances can be achieved via instances of StructuralMemberType.
StructuralMember should be used as a base of any specialized class.
Equivalent to IfcStructuralMember.
StructuralPhysicalModel (Structural Physical Model) EntityClass Deprecated
PhysicalModel should be used in place of this class.
Base Class: BisCore:PhysicalModel
Inherited properties
| Name | Description | Type | Extended Type |
|---|---|---|---|
| ParentModel | The parent bis:Model contains the bis:Element that this bis:Model is sub-modeling. | navigation | |
| ModeledElement | The bis:Element that this bis:Model is sub-modeling. This bis:Model models the same Entity as the sub-Modeled bis:Element, but at a finer granularity. | navigation | |
| IsPrivate | If IsPrivate is true then this bis:Model should not appear in lists shown to the user. | boolean | |
| IsTemplate | If IsTemplate is true then this bis:Model is used as a template for creating new instances. | boolean | |
| JsonProperties | A string property that users and/or applications can use to persist ad hoc JSON values. | string | Json |
| LastMod | The last time any element in this Model was modified. | dateTime | |
| GeometryGuid | A GUID that changes whenever any element in this GeometricModel has a change to its geometry. | binary | BeGuid |
| IsNotSpatiallyLocated | If IsNotSpatiallyLocated is true, then the elements in this bis:GeometricModel3d are not in real-world coordinates and will not be in the spatial index. | boolean | |
| IsPlanProjection | If IsPlanProjection is true, then the elements in this bis:GeometricModel3d are expected to be in an XY plane. | boolean |
This class has been deprecated. Do not use.
Applications, services and components should never create instances of this class. Use PhysicalModel instead.
Wall (Wall) EntityClass
Base Class: StructuralPhysical:StructuralMember
Inherited properties
| Name | Description | Type | Extended Type |
|---|---|---|---|
| Model | The bis:Model that contains this bis:Element. | navigation | |
| LastMod | The last modified time of the bis:Element. This is maintained by the core framework and should not be set directly by applications. | dateTime | |
| CodeSpec | The CodeSpec property identifies the bis:CodeSpec used to generate and validate the code value for this bis:Element. The combination of CodeSpec, CodeScope, and CodeValue properties must be unique for each bis:Element instance. | navigation | |
| CodeScope | The CodeScope property identifies the bis:Element that provides the uniqueness scope for the code value. The combination of CodeSpec, CodeScope, and CodeValue properties must be unique for each bis:Element instance. | navigation | |
| CodeValue | The CodeValue property stores a human-readable real-world identifier of the Entity represented by the bis:Element. The combination of CodeSpec, CodeScope, and CodeValue properties must be unique for each bis:Element instance. | string | |
| UserLabel | An optional friendly name given by the user (as opposed to the formal name stored in the CodeValue property). | string | |
| Parent | The parent bis:Element that owns this bis:Element. | navigation | |
| FederationGuid | The GUID used to federate this bis:Element across repositories. | binary | BeGuid |
| JsonProperties | A string property that users and/or applications can use to persist ad hoc JSON values. | string | Json |
| Category | The bis:SpatialCategory used to categorize this bis:GeometricElement3d | navigation | |
| InSpatialIndex | If true, this element will have an entry in the Spatial Index. | boolean | |
| Origin | The placement origin of this bis:Element. | point3d | |
| Yaw | The Yaw angle (in degrees) of the orientation of this bis:Element. | double | |
| Pitch | The Pitch angle (in degrees) of the orientation of this bis:Element. | double | |
| Roll | The Roll angle (in degrees) of the orientation of this bis:Element. | double | |

| PhysicalMaterial | Indicates the bis:PhysicalMaterial of which the bis:PhysicalElement is made. | navigation |
A Wall is a vertical construction element that can enclose or divide spaces. Walls are typically vertical or nearly vertical, planar elements, often designed to bear structural loads.
Classification of Wall instances can be achieved via instances of WallType. Walls must be contained in PhysicalModels.
Equivalent to IfcWall.
