Hi tuananhnp, sorry no Moi doesn't have sub-d modeling functionality like that as of yet.

It does have a sub-d converter though so that you can bring in a sub-d model to use as a base object in MoI.

You do that by using a separate poly modeling program to do the box modeling and then bring the result over into MoI using the SubD > Convert > "From file" conversion tool in MoI.
