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 ?
