Thank you very much for answering. 
I don`t have Rhino. 
I`ve made scan of plastic bottle (SLS) and I wanted make bottle container. I`ve made Zbrush automatic retopology (quads). Imported it as obj to MoI3d. Next I used Subd MoI plugin to smooth it out. Mesh is dense but bolean operation on cube container worked just fine. 
  
I hope in future MoI3d will have ools for resurfacing (new topology). It should allow manually create surface based on 3d scans. I think it`s actual topic becouse of 3d printing and scanning times. Or maybe some automatic solution to make that process more avaible ;)
 
Thanks Michael for that link with technique that is also a good way.
