Evan Yares takes a closer look at Creo Freestyle and why it should matter to designers:
The Freestyle extension in PTC’s Creo Parametric 2.0 program is one of the most interesting SubD surface modelers. It’s not only included at no extra charge with the base program, it’s well-integrated with Creo’s parametric modeling capabilities, allowing you to create aesthetic surfaces with SubDs, and precise surfaces (for interfaces) with NURBS.
He concludes with a head-to-head video from PTC that compares working with surfaces in Creo Freestyle versus Pro/ENGINEER Wildfire 5.0:
While it’s likely that PTC is trying to encourage their Pro/E users to upgrade to Creo, the video really highlights the difference in modeling methodology using SubD surfaces versus NURBS surfaces. It’s worth a watch, even if you’re not a Pro/E or Creo user, because it shows what can be done with SubD surfaces. If you do any kind of aesthetic surface design, you want SubDs.
