Implementation

All important work is done inside TransformDlg::OnApply() handler for the Apply button

IModel* iModel = (IModel*)m_kernCAD.GetModel();

retrieves IModel interface, from which all other interfaces are accessed.  Interface to the current entity is kept into iSect variable. It is obtained in the same procedure using calls identical to

An instance of ITransform interface implemented by the object is obtained with a query: 

iSect->QueryInterface(IID_ITransform, (void**)&iTransf);

m_kernCAD.UpdateSurface();

call in the end of the function is required to recalculate surface of the object after changes of its parameters.

The offset operation is performed with IMeshMods.Offset in the same function. IMeshMods is obtained via query ISection > IMesh > IMeshMods.
