| | HandOrientation | Property to get the orientation of family instance hand. |
| | Host | If the instance is contained within another element, this property returns the containing element. An instance that is face hosted will return the element containing the face. |
| | HostFace | Property to get the reference to the host face of family instance. |
| | HostParameter | If the instance is hosted by a wall, this property returns the parameter value of the insertion point of the instance along the wall's location curve. |
| | Id | A unique identifier for an Element in an Autodesk Revit project. (Inherited from Element .) |

| | IsSlantedColumn | Indicates if the family instance is a slanted column. |
| | IsValidObject | Specifies whether the .NET object represents a valid Revit entity. (Inherited from Element .) |
| | IsWorkPlaneFlipped | Identifies if the instance's work plane is flipped. |
| | LevelId | The id of the level associated with the element. (Inherited from Element .) |
| | Location | This property is used to find the physical location of an instance within project. (Overrides Element Location .) |
| | MEPModel | Retrieves the MEP model for the family instance. |
| | Mirrored | Property to test whether the family instance is mirrored. (only one axis is flipped) |
| | Name | A human readable name for the Element. (Inherited from Element .) |
| | OwnerViewId | The id of the view that owns the element. (Inherited from Element .) |
| | Parameter Guid | Retrieves a parameter from the element given a GUID for a shared parameter. (Inherited from Element .) |
| | Parameter String | Retrieves a parameter from the element given its name. (Inherited from Element .) |
| | Parameter BuiltInParameter | Retrieves a parameter from the element given a parameter id. (Inherited from Element .) |
| | Parameter Definition | Retrieves a parameter from the element based on its definition. (Inherited from Element .) |
| | Parameters | Retrieves a set containing all of the parameters that are contained within the element. (Inherited from Element .) |
| | ParametersMap | Retrieves a map containing all of the parameters that are contained within the element. (Inherited from Element .) |
