You could look at Blender,which is a free program that will allow you to create 3D models from 2 and 2.5D vectors. In the paid category, Vectric Aspire is very good - pricey, but very good. You can use their trial version for free to determine if it is what you are looking for. You may want to look at the Carveco offerings. They are subscription based. I'm not sure if they can do what you want, though.
