Has anyone seen problems with generating artwork files
using the Gerber RS274x Format on Cadence?  We are
running version PE13 still and I recently sent out a board
using this "new" Gerber only to find out that one of the
shapes on the top layer did not plot- No errors nor warnings
regarding this were given and the boards will have to be
reworked at a considerable cost and loss of time in the factory.
