FamilyInstance Properties

The FamilyInstance type exposes the following members.

Properties

	CanFlipHand	Property to test whether the orientation of family instance hand can be flipped.
	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)
	DemolishedPhaseId	Id of a Phase at which the Element was demolished. (Inherited from Element)
	DesignOption	Returns the design option to which the element belongs. (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.
	FromRoom[Phase]
	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 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[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)
	Parameter[Guid]	Retrieves a parameter from the element given a GUID for a shared parameter. (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).
	Room[Phase]
	Space	The space in which the instance is located (during the last phase of the project).
	Space[Phase]
	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.
	SuperComponent	Property to get the super component of current family instance.
	Symbol	Returns or changes the FamilySymbol object that represents the type of the instance.
