Creo Surfacing Restyle & Reverse Engineering REX

Description

Learn to transform physical products from digital scan data into digitally-correct complex Creo surface & solid geometry as an integral part of your product development process. Participants will learn to manipulate point cloud imports scanned from clay or existing products using Creo Restyle to learn Reverse Engineering Extension workflows and techniques. 

Using Creo to reverse engineer enables a productive use of imports in Creo Assemblies of intellectual property, for checking interference to develop more effective products.

This Creo Restyle Reverse Engineering training class is a two-day intensive course developed for seasoned product designers and engineers. We guide you in creating surfaces and solids from scan data with a series of hands-on exercises.
