The purpose of this critical text is to give direct feedback to developers at PTC.
Creo Parametric 3.0 is such an inefficient software compared to other modeling tools. I don't want to tell names here, but I work with two other well known CAD tools. Modeling with Creo means you have to make cumbersome steps to reach your goal. Many things can be done much faster with other software. Most disappointing point is, that you often can't undo certain steps. You often have to search for a feature or an option, where with other tools you are one step ahead.
I can imagine that PTC has some difficulties transforming Pro/E from an direct modeling to a parametric system. This would explain a lack of a proper organized modeling environment everybody can work with intuitively.
All in all, Creo at the current state is not efficient enough and I would not recommend it.
