Managing Unknown Objects

QuickDraw 3D creates an unknown object when it encounters an unrecognized type of object while reading a metafile. Your application might know how to handle objects of that type, so QuickDraw 3D provides routines that you can use to get the type and contents of an unknown object.

Note
You cannot explicitly create an unknown object.
