"Lost in Translation" was the title of a film. And the perfect title here i think. This field is wide. Down to the bottom it has to do with curve descriptions. Wether Vue is not able to read them correctly or the providing software is not able to write them as needed. Both is possible. Even 3DS is not completely standardised so that there are variations. And therefore misunderstandings between software packages. You need to do testings which export format of the software you use for modeling is best for importing into Vue. I sometimes have to do chains. Export it from Cinema in one format, import it into Amorphium (or Amapi or Poser or...) and export it in another format from there again to get good results. It is anoying but who do you want to blame? Indeed, a visual smoothing will not help because the original model (for Vue the imported one is "the original") has not enough facets. What i have sometimes done even is to exchange spline curves (or nurbs) with simple polygons (very fine ones) to be sure that nothing can happen in translation there. That is the effect Paul is talking about. DXF (when i remember it right) does not support any sort of spline curves. So the export filter of the modeling software has to make fine polygon lines out of them while the 3ds contains spline desciptions that Vue misinterpretates.
