Supply us with a sample .vnc (GibbsCAM) file that uses all of the features for which you will need the postprocessor to create code.  Post the job with a GibbsCAM library postprocessor.  Modify the posted output to your liking, including why you are changing the particular code.  We will need the .vnc file, the original posted file and the modified file to provide a quotation for the post you desire.
