With the context menu sections of a 3D view can be cut or copy and paste into another normal view or 3D view. Conversely, sections can also be cut or copy from a normal view to be pasted in the 3D view.
When a layer is pasted from a 2D to 3D, the user will be able to choose the same options (elevation or image, rasterization of vectors) that if the layer were added directly from the data source.
