You'll need to visualize each roof plane individually in a Parallel 3D view. Select in plan and then view selected as 3D.
In the Internal Rendering 'hidden line' method, apply the "Look to perpendicular of clicked surface" to get an orthographic view of the plane as edges. Copy this to a floor plan view. The assembled views can then be exported via DWG to the cutter.
