The FamilyInstance type exposes the following members.
Properties

| CanFlipWorkPlane | Identifies if the instance can flip its work plane. |
| CanRotate | Property to test whether the family instance can be rotated by 180 degrees. |
| CanSplit | Identifies whether a particular family instance can be split at a point on it's defining curve (by Split(Double)). |
| Category | Retrieves a Category object that represents the category or sub category in which the element resides. (Inherited from Element.) |
| CreatedPhaseId | Id of a Phase at which the Element was created. (Inherited from Element.) |

| Document | Returns the Document in which the Element resides. (Inherited from Element.) |
| ExtensionUtility | Property to check whether the instance can be extended and return the interface for extension operation. |
| FacingFlipped | Property to test whether the orientation of family instance facing is flipped. |
| FacingOrientation | Property to get the orientation of family instance facing. |
| FromRoom | The "From Room" set for the door or window in the last phase of the project. |
| FromRoomPhase | |
| Geometry | Retrieves the geometric representation of the element. (Inherited from Element.) |
| GroupId | The id of the group to which an element belongs. (Inherited from Element.) |
| HandFlipped | Property to test whether the orientation of family instance hand is flipped. |
| HandOrientation | Property to get the orientation of family instance hand. |
| HasSpatialElementCalculationPoint | Identifies if this instance has a single SpatialElementCalculationPoint used as the search point for Revit to identify if the instance is inside a room or space. |
| HasSpatialElementFromToCalculationPoints | Identifies if this instance has a pair of SpatialElementCalculationPoints used as the search points for Revit to identify if the instance lies between up to two rooms or spaces. |
| 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, as long as the family of the instance isn't work plane based. |
| Id | A unique identifier for an Element in an Autodesk Revit project. (Inherited from Element.) |
| Invisible | Property to test whether the family instance is invisible. |
| IsModifiable | Identifies if the element is modifiable. (Inherited from Element.) |
| IsSlantedColumn | Indicates if the family instance is a slanted column. |
| IsTransient | Indicates whether an element is transient or permanent. (Inherited from Element.) |
| 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 ElementLocation.) |
| 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.) |
| ParameterGuid | Retrieves a parameter from the element given a GUID for a shared parameter. (Inherited from Element.) |
| ParameterBuiltInParameter | Retrieves a parameter from the element given a parameter id. (Inherited from Element.) |
| ParameterDefinition | 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.) |
| Pinned | Identifies if the element has been pinned to prevent changes. (Inherited from Element.) |
| Room | The room in which the instance is located (during the last phase of the project). |
| RoomPhase | |
| Space | The space in which the instance is located (during the last phase of the project). |
| SpacePhase | |
| StructuralMaterialId | Identifies the material that defines the instance's structural analysis properties. |
| StructuralMaterialType | This property returns the physical material from which the instance is made. |
| StructuralType | Provides the primary structural type of the instance, such as beam or column etc. |
| StructuralUsage | Provides the primary structural usage of the instance, such as brace, girder etc. |
