Sviluppo Virtuale del Prodotto 7 / 21
Overview and aims
Partners for the Advancement of Collaborative Engineering Education (PACE)
The PACE consortium has the main objective to disseminate and increase knowledge and practical tools for the development of industrial product (CAD, CAE) and the culture of the PLM (Product Lifecycle Management) that allows to integrate all processes and systems configuring the business process from product development to production to parts in a single workflow and information.
Now, the Politecnico of Torino, thanks to its partnership with the PACE consortium, can offer all the advantages given by the software of the PACE project, to all of its student
