*2.1. Sample*

The sample consisted of 65 civil engineering undergraduate students from the University of La Laguna. A proportion of 30% the students knew PLM applications for collaborative work in CAD environments. However, 95% of the them had not worked in a collaborative 3D modeling experience. They considered that group work in engineering environments is very important for their professional activity and 97% reflected that working with cloud-based data is fundamental for an engineer.
