You can use the Q3Object_GetLeafType function to get the leaf type of a QuickDraw 3D object.

A QuickDraw 3D object.

DESCRIPTION

The Q3Object_GetLeafType function returns, as its function result, the leaf type identifier of the QuickDraw 3D object specified in the object parameter. You should call this function only when the specified object is a leaf object (for example, when you've read the object in from a file). If the leaf type cannot be determined or is invalid, Q3Object_GetLeafType returns the value kQ3ObjectTypeInvalid.
