I use Rhino for 99.9% of my modeling.. I got it 3 years ago and have never looked back.. I wouldn't want to use anything else.. For me Carrara's modeling is weak..But that's because I'm used to CAD like precison and accuracy.. It depends on what you want to get out of it.. For some things Carraras modeling tools are fine, and then for others, Carrara can't even begin.. Amapi 5 is worth learning, hell it's free with Carrara, .. I think they give it with Carrara because they know that most people are going to want to model with better tools... Nurbs cannot be compared to what is offered in Carrara.. They are vastly superior.. It's like comparing bitmaps to vectors.. 2 different universes...But I do love Carrara for it's Scene/Texturing/Animation/Export/rendering features... I wonder if Eovia is looking into adding Nurbs modeling to Carrara in the future? It would make it a much more powerful program.. kaom
