Problems with Gerber data from Expedition

Hello  All,


For some of our customers we have to create Gerer data. We create this data from the Expedition Output menu.  When importing  the generated data into a gerber viewer like Pentalogix's Viewmate we find that the generated gerber data contains so-called 'self-intersecting polygons'. As a PCB-designer I simplie ignore these errors and perform a visual check of the generated data.



If i send these files to the pcb manufacturer, the moment the manufacture finds these errors, the production stops and I receive an error report and a request to 'repair' the gerber data. The only way I can do this right now is by importing the Gerber data into Gerbtool (Wise) and perform a save.


Does anyone recognize this problem and , more importantly, how do you deal with this ?
