Paneling Tools Morph3D smooth morphing

Hello, in order the use the smooth morphing function of the Morph3d node, I need to input the surfaces of grid1 and grid2 which is the offset grid. But I don’t know how to convert them into a surface or the polysurface of the Brep I’m trying to panel. Also the offset that the offset grid node does, how can I recreate it to offset the original surface and input into surface for grid2?
