I am trying to open an IDF file from OrCAD PCB Editor.  When I open it, all of the components on the top side look correct, but the components that are rotated at 90 or 270 degrees are reversed.  I have tried checking the "Reverse Underside Components" box, which has no effect.  I believe I could fix this by changing the part origin from pin 1 to the part center, but I'd rather not have to do that for all of the parts on my board.  Is there some trick to getting my bottom side components to come in correctly?
