We have migrated to Creo 2.0 and are having issues with fixtures. In the past we did not classify a lot of things as fixtures, we have mostly used "gen assy". Sincefixtures are causing us problems in Creo 2.0, we are wondering if there is a real advantage to try to get them to work. Most of our parts are near net shape castings on fixtures or made using vise setups. What are the major advantages of classifying items as fixtures?
