My commercial works - packaging

[champ]

How do you get the schematics for the packing I've noticed that it has odd shapes on some of your packing. Is their a template for Xara for the Shapes to make it into a foldable printable product that you can design in Xara? Also how would you go about making the perspective properly like shown in your drawings of product box? It seems really hard to get the text and images on proper perspective then again I'm still new to the drawing version of photo & graphic designer.
