You should do some reading and learn the basics of polygon modeling to understand how things will smooth.
With "unsmoothable" I mean that the model isn't modelled with smoothing in mind and thus will look like crap when smoothed.
OK.., good idea.., never thought of that, maybe i'll ask my teacher now that im at CGI school.., he might know something about it too!!
thanks 
take it easy and life will be easy
