I was perfectly happy using Creo 4.0 for my day-to-day design tasks with no real sense of urgency to move to a newer release of the software. Then I was asked to investigate Creo 7.0 to determine whether there were tools or workflows that could benefit the way our organization creates and leverages their solid models.
After working with Creo 7.0 for a couple of days, I went from little sense of urgency to upgrade to “How soon can we get this rolled out and into the hands of our users?”
In fact, I am encouraging all my customers to make that move as soon as possible, and the reasons for doing so are many.
