v9.0 (2011)

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.

This method differs from X3DObject.FindChild because this method will not return itself if its family matches the specified family. For example, calling 'cube.FindChild("", siMeshFamily)' will return the cube itself but this method will return null.

X3DObject X3DObject.FindChild2( Object in_varName, String in_pbstrType, Object in_famArray, Boolean in_bRecursive );

oReturn = X3DObject.FindChild2( [Name], [Type], [Family], [Recursive] );

X3DObject

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 siAttractorCtrlType Attractor Control Object type (electric force) siCameraPrimType Camera Primitive type siCameraRootPrimType Camera Root primitive type siChainBonePrimType Chain Bone Primitive type siChainEffPrimType Chain End Effector Primitive type siChainRootPrimType Chain Root Primitive type siCirclePrimType Implicit Circle Primitive type siCloudPrimType Cloud Primitive type siConePrimType Cone Primitive type siCrvListAggregatePrimType NURBS Curve List Aggregate Primitive type siCrvListPrimType NURBS Curve List Primitive type siCubePrimType Cube Primitive type siCylinderPrimType Cylinder Primitive type siDiscPrimType Disc Primitive type siDodecahedronPrimType Dodecahedron Primitive type siDragCtrlPrimType Drag Control Primitive type siEddyCtrlPrimType Eddy Control Primitive type siFanType Fan Force Object type siFurPrimType Fur Primitive type siGeoShaderPrimType GeoShader Primitive Type siGravityCtrlType Gravity Force Control Object type siGridPrimType Grid Primitive type siIcosahedronPrimType Icosahedron Primitive type siLatticePrimType Lattice Primitive type siLightPrimType Light Primitive type siModelNullPrimType Model Null Primitive type siModelType 3D Model type siNullPrimType Null Primitive type siOctahedronPrimType Octahedron Primitive type siPolyMeshType Polygon Mesh type siSpherePrimType Sphere Primitive type siSpiralPrimType Implicit Spiral Primitive type siSpotInterestPrimType Spot Interest Primitive type siSpotRootPrimType Spot Root Primitive type siSquarePrimType Implicit Square Primitive type siSrfMeshPrimType NURBS Surface Mesh Primitive type siTetrahedronPrimType Tetrahedron Primitive type siTorusPrimType Torus Primitive type siTurbulenceCtrlPrimType Turbulence Control Primitive type siVolumeDeformType Volume Deform type (implicit sphere volume) siVortexCtrlType Vortex Control Object type (magnetic force) 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 siGeometryShaderFamily Geometry shader family siImplicitGeometryFamily Implicit Geometry family siLatticeFamily Lattice family siLightPrimitiveFamily Light Primitive family siMeshFamily Mesh Geometry family siNullPrimitiveFamily Null Primitive 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

Python Example

#
# FindChild vs. FindChild2 Python Example
#
from win32com.client import constants as const
Application.NewScene("", False)
# Create a cube
Application.CreatePrim("Cube", "MeshSurface", "cube", "")
root = Application.ActiveSceneRoot
cube = root.FindChild("cube")
# Use "FindChild" to get the first child of the cube of "siMeshFamily" family;
# NOTE: FindChild also considers the parent object if it is of the same family
child = cube.FindChild("", "",const.siMeshFamily)
# FindChild returns the cube itself as its first child
Application.LogMessage("FindChild : " + child.Name)
# Use "FindChild2" to get the first child of the cube of "siMeshFamily" family;
# NOTE: FindChild2 always ignore the parent regardless of its family
child = cube.FindChild2("", "",const.siMeshFamily)
# FindChild2 returns the first child of the cube, none in this example
if not child:
	Application.LogMessage("FindChild2: <none>")
else:
	Application.LogMessage("FindChild2: " + child.Name)
# Expected results:
# INFO : FindChild : cube
# INFO : FindChild2: <none>
