Really? Cheez... the pdf-format really sucks as online manual.
Anyway, target helper -object can be placed using either button in
the toolbar (button with several circles, tries to look like a
shooting target) or via insert menu. It's basically a non-renderable
object (looks like several lines crossed and a hotpoint in the
middle) that is used mainly as
-target for point-at behaviour
-target for track behaviour
Other good use is to group model and target, apply a deforming
modifier to the group and move the target inside the group. As
modifiers modify the objects by the volume of the bounding box, you
can change and animate the effect of the modifier by moving the
target helper around.
I can't help you more until i get carrara reinstalled and files
unpacked from my backups.
