Hi Stardust,

No, unfortunately it's like 3dcnc says above - the way that the model data is structured in MoI and in other CAD programs is with having large spline surfaces that are joined to each other at trimming boundary edges. This type of structure works very well for mechanical objects and allows for very accurate boolean operations but it is not very suited for lumpy bumpy organic type shapes like you would get with ZBrush.

The way ZBrush represents geometry is totally different, objects over there are made up of a whole lot of little polygon elements. That type of structure then does not work well for booleans but it does work well for brush sculpting functions.

If you want to use brush type functions, you will need to export your model into ZBrush or a similar type of organic deformation type modeler, MoI is focused on an entirely different kind of modeling style than that.

Different modeling programs use different fundamental methods for representing objects and each different method has its own set of strengths. MoI's method is heavily focused on building mechanical objects using profile curves and boolean operations. ZBrush has a very different approach.

It's not just a difference only in UI or scripting, but a difference in how the 3D model data itself is structured.
