Traditionally, when doing surface design work, you need to spend a lot of time figuring out how to best get the surfaces to flow and be as smooth as you require them to be. A lot of the time you need to have a certain level of expertise to achieve this. But, Creo Parametric introduces new capabilities for freeform surface design, which comes in the form of Creo Parametric freestyle. This is standard with all seats of Creo Parametric.
WHAT IS DOES CREO PARAMETRIC FREESTYLE OFFER USERS?
Freestyle introduces a new concept. You no longer need to worry about the complexities of setting up the surface area, as the system is now able to take care of this for you. All you need to worry about is the specific form you are trying to build.
