Creo 4.0 from PTC is set to release in mid December and has many new features we are excited about. It includes tools to improve productivity and has also been optimized for model based enterprise and 3D printing. So while you may be content with your old version of Creo or Pro/ENGINEER, we promise the new features are worth the upgrade.
Creo 4.0 from PTC has changed the way you interact with 3D models. Context sensitive toolbars have replaced geometry based selections allowing for increased productivity. Instead of searching for relevant menu options, context-sensitive commands are available at your fingertips.
