Imagine has randomly oriented faces.  Wavefront uses the outward
normal to determine the orientation of faces.  InterChange cannot
magically determine the proper orientation of all the faces.  (If
someone has an algorithm for this, please educate me.)

The Wavefront "orient #" command (not the button command) will attempt
to orient the faces properly, but it only works on a single
sub-object, not the entire set of sub-objects in your scene.

Or, you can copy all the faces to another object, flip all the faces,
and then re-merge the two.  Of course, this doubles the number of
faces in the object.

By the way, we don't have a registration for you.  Did you register
your copy of InterChange?
