The base problem with all substandard work (CAD/CAM being NO exception) in all of its manifestations from concept (screen doors for submarines), drawing, checking, manufacturing, installation, and customer buyoff, is to CHECK the work and what your part of the proocess is.
The author would do well to implement this piece of advice by doing a complete scan of his entry for spelling, grammer, and just plain sentence structure.
The old addage holds true here, clean your own house first.
