Not from the drawings.. directly from the 3D model. Of course, if your outsourcing your CNC work you'll want to include a "control" drawing that shows critical tolerances.
I've designed and built many fairly complex plastic injection molds and prototypes without a single drawing. It's very fast and accurate if you have control over all the processes. The outside tool houses we use "HAVE" to accept 3D models to qualify as vendors. The ones that truley utillize all of the advantages of 3D data do a much better job.
