Hi SI-LIST, Thanks in advance for your help and thanks for many years of good reading. This is not an SI question per se but deals with issues relating to translation into SI/PI/Gerber generation tools from our various vendors. What often makes this so difficult is that because the translation problems often span multiple vendors it is difficult to pin one vendor down to fix it. We have had a great deal of agita, time and money spent, just trying to get accurate translations from our PCB tool into our SI/PI tools. One problem in particular has been problems with SELF-INTERSECTING POLYGONS that cause the translators to either gag or produce incorrect fills or via structures In addition, this ongoing problem is often version dependent. What seems to work with one collection of tool versions is broken when one of the vendors comes out with a new version. Have others run into these ongoing problems and if so how have you been able to handle it?
