One of the big game changers in Creo 3.0 was the new multi-CAD functionality. Called “Unite,” this breakthrough technology tackles the challenge of working in an environment where not everybody has the same CAD system.
While Creo has worked toward better multi-CAD performance for years, this release amplified the vision of a world where engineers no longer find themselves locked into a single file format. Now, there are no intermediate translation steps and no fixing and repairing models. Best of all, you’ll have fewer reasons than ever to recreate parts from scratch.
Creo Parametric with Unite helps manufacturers collaborate more effectively across teams and drive the consolidation of CAD systems.
