Hi Elang, sorry no generally it isn't possible to do the same type of control point editing on NURBS surfaces as you would do in a poly modeling program.

The fundamental reason is because you can't add in a single new point on a NURBS surface, NURBS surfaces are defined by a grid of points with rows and columns. You can't insert a single point you can only insert an entire row or column.

Yes, that type of surface point editing is not a focus of Moi's toolset. If you need to sculpt control points to make organic shapes like you describe you are better off doing that in a poly modeling/subd program which is entirely focused on that type of work and has many other tools to support it.

MoI isn't the right tool to do that type of 3D control point editing.

But you can use a hybrid workflow with MOI where you can incorporate the end result of your sub-d model as a base surface in MOI using the sub-d conversion tool in MOI under SubD > Create > "From file".

MOI's type of modeling works well on things that are primarily defined by 2D profile curves, especially mechanical type shapes and using boolean operations.
