Incorporating an stl model in Moi

 From:  ggagnon

Many models available to carving people come in stl format only.
I would like to create a model in Moi, import one of those stl model then save it as an stl file. I don't need to edit the stl portion.
There is no option to import stl file in Moi. Beside resorting to Rhino, how could I do this?
Thanks,
Gaston
