From scratch or using one of the Design and Make models?
If it's from scratch then you can't really do that in VCarve (although it does depend to some extent exactly what it is that you want to do) as VCarve doesn't have the tools to create models. Only Aspire has that capability in the Vectric product range.
If it's an existing model that you want to machine then VCarve (v8 and on) can certainly do that and there is a whole range of tutorial videos available at http://support.vectric.com
that will show you how.
