I think my originl question may have been slightly misinterpereted, I'm interested in knowing what specific software HASTAK actually use.

As helpful as peoples suggestions have been and I will be checking out each of these packages, just for curiosity's sake if nothing else. I'm keen to know what HASTAK use so I can either find a cheap/free cut down version to play with or something similar to what they use. that way I can develop an insight into the way they develop the toys/figures.

it may even be something they have developed in house?

Who knows I may even be able to build up a portfolio and eventually get a job with them working remotely in Australia. wishful thinking I know.
