Wel the intention is to create the 3D model programatically using a 3rd part program,and then create the file that can be used in Carrara. So the question is what file format (if possible text only) could be used so that I can load that model into carrara to be used. 

Maybe the SDK and then, create some plugin when I can find time? 

The idea behind is, that I somhow want to create company results into some spectacular visual way and it would be nice if I can half automati it in some way. Maybe too far fetached ;-)
