AS3/PV3D Need a quich hand to get started


I’m trying to learn PV3D, using examples I can find from the web, can someone tell me why a lot of tutorials seem out of date compared to the as3/trunk/src I have downloaded on my machine.
A lot of examples use Plane, and this class (org.papervision3d.objects.Plane;) is clearly removed (?) from the latest packages…!!

Help! How can I get started the right way ?

Many thanks to you !
