## X3DObject.FindChild

### Deprecated

v9.0 (2011)--see X3DObject.FindChild2

### Description

Finds the first X3DObject child object of an X3DObject that matches a set of search criteria. The search is done recursively by default, the function returns the object that meet all supplied criteria i.e. name, type and family(ies). This function is typically used for retrieving an object if you know its type or name for instance.

### C# Syntax

    X3DObject X3DObject.FindChild( Object in_varName, String in_pbstrType, Object in_famArray, Boolean in_bRecursive );

### Scripting Syntax

    oReturn = X3DObject.FindChild( [Name], [Type], [Family], [Recursive] );

### Return Value

X3DObject

### Parameters

Parameter | Type | Description
--- | --- | ---
Name | String or CollectionItem | A name expression or a CollectionItem, the expression can also contain wildcard characters. The name can be empty if the name is not required.
Type | String | The type of object defined by siType or an empty string if no type is used. The type can be a specific X3DObject type such as siModelType and si3DObjectType or a primitive type such as siPolyMeshType or siSrfMeshPrimType. If a primitive type is supplied, the function considers only the children objects defined with a primitive of this type. The valid types are listed below.
Possible Values: | Description:
si3DObjectType | 3D Object type
siArcPrimType | Implicit Arc Primitive type

siWaveCtrlType | Wave Control Object type
siWindType | Wind Force Object type
Family | siFamily or Array of siFamily elements. | An array of families defined by siFamily or an empty array if none are required. The families are used for narrowing down the search, the array can contain X3DObject families like si3DObjectFamily or primitive families such as siNurbsSurfaceMeshFamily or siNullPrimitiveFamily. Only the children objects that match the supplied families are considered. If primitive families are supplied then only the objects defined with a primitive that belongs to one of them are considered. The valid families are listed below.
Possible Values: | Description:
si3DObjectFamily | 3D Object family
siCameraFamily | Camera family
siChainElementFamily | Chain Element family
siControlObjectFamily | Control Object family
siCurveFamily | Curve Geometry family
siGeometryFamily | Geometry family

siNurbsCurveListFamily | Nurbs CurveList Geometry family
siNurbsSurfaceMeshFamily | Nurbs Surface Mesh Geometry family
siSurfaceCurveFamily | Surface Curve Geometry family
siSurfaceFamily | Surface Geometry family
Recursive | Boolean | Recurse if True, otherwise the search is done on the immediate children. Default Value: True
