NewFamilyInstance Method (XYZ, FamilySymbol, StructuralType)

Inserts a new instance of a family into the document, using a location and a type/symbol.

Namespace: Autodesk.Revit.Creation
Assembly: RevitAPI (in RevitAPI.dll) Version: 17.0.0.0 (17.0.1090.0)

Syntax

C# 
public FamilyInstance NewFamilyInstance(
	XYZ location,
	FamilySymbol symbol,
	StructuralType structuralType
)
Visual Basic 
Public Function NewFamilyInstance ( _
	location As XYZ, _
	symbol As FamilySymbol, _
	structuralType As StructuralType _
) As FamilyInstance
Visual C++ 
public:
FamilyInstance^ NewFamilyInstance(
	XYZ^ location, 
	FamilySymbol^ symbol, 
	StructuralType structuralType
)

Parameters

location
Type: Autodesk.Revit.DB XYZ
The physical location where the instance is to be placed.
symbol
Type: Autodesk.Revit.DB FamilySymbol
A FamilySymbol object that represents the type of the instance that is to be inserted.
structuralType
Type: Autodesk.Revit.DB.Structure StructuralType
If structural then specify the type of the component.

Return Value

A valid instance of the given family if the creation is successful. An exception will be thrown otherwise.

Remarks

Use this method to insert a family instance that does not require a host element or level. For creating instances of level-based families use one of the NewFamilyInstance methods of the Revit.Creation.Document class.

The type/symbol that is used must be loaded into the document before this method is called. Families and their symbols can be loaded using the Document.LoadFamily or Document.LoadFamilySymbol methods.

Some Families, such as Beams, have more than one endpoint and are inserted in the same manner as single point instances. Once inserted these linear family instances can have their endpoints changed by using the instance's Element.Location property.

Note: if the created family instance includes nested instances, the API framework will automatically regenerate the document during this method call.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException Thrown if the symbol is not active.
Autodesk.Revit.Exceptions InvalidOperationException Thrown if the family is level-based, for new instances of such families require a valid level to be supplied at the time of creation.
