Khalid,
Cut3D will slice large / thick models into portions that are equal to the available material thickness. The toolpaths for each slice of the model only machine the 3D portion - the sides of the model and don't waste time cutting the flat top surface of the material.
Each slice can be machined using just Cut3D. It's also possible to use VCarve Pro to setup and machine multiple slices from a single sheet of material. Save each slice + toolpaths in Cut3D and then Import all the slices (.v3d files) into VCarve Pro and move them around to allow multiple pieces to be machined from the material in one go.
I hope this makes sense and below is an image that might help.
Notice that models such as the 3D head shown in the image below can automatically be sliced above and below a plane passing through the model. So both sides can be machined and assembled.
