Can anyone tell me how to join objects in Carrara. When I import two objects into the Assembly room, I can't seem to get them both into the Vertex modelling room at the same time so that I can join them together and work on them together. I know I can create numerous primatives in the modelling room and work on them but it seems impossible to import multiple objects (two would do!). I would like to be able to construct one piece of my final object, save it, construct another piece, save that, construct a third piece, then join them all together. Surely that is possible, or what use is the modelling room?
