messageSize (4 bytes): A 32-bit unsigned integer. The total size of this message and its payload in bytes. The value of this field MUST be set to a number divisible by four and greater than or equal to 0x00000010.

controlCode (4 bytes): A 32-bit unsigned integer containing the control code for this message. The value of this field MUST be equal to 0x00000081.

targetResource (4 bytes): A 32-bit unsigned integer. This field MUST be set to a valid resource handle referencing a resource of type TYPE_GEOMETRY2DGROUP. This handle identifies the resource that is the target for this message.

ChildrenCollectionSize (4 bytes): A 32-bit unsigned integer. The size in bytes of the ChildrenCollection array.

ChildrenCollection (variable): A variable-length array of handles to resources of type TYPE_GEOMETRY2DGROUP or TYPE_MESHGEOMETRY2D (as defined in section 2.2.1). Describes the 2-D geometry resources that are contained in this geometry 2-D group. The number of elements in this array MUST be equal to the value of the ChildrenCollectionSize field divided by four.
