I understand that you are frustrated. But I do hope you don't quit on the image. I thought Carrara 8.1 had draping. I haven't used it though. And it definitely has assembly room modelling with soft selection tools - you can fake-drape it over the bones :). Unlike actual bodies this doesn't need to be precise and it even doesn't need to follow the pose very closely, so it's a good situation for fake-draping.

I am still using Carrara 8.1, because it fits all of my needs. And the image is about your art, not DAZ. The challenge is also not about DAZ, it's about Carrara, which even at version 8.1 is a very cool piece of software :).
