First on the V6, now on the V7. It is true that the V6 presentation was difficult to use for an untrained user. (students on internships for example). We have just migrated to TOPSOLID V7, so training of our design office in our premises. In the group, there were 2 young people, 1 engineering student and a 20-year-old colleague who had never worked in 3D design..... These 2 boys immediately understood this interface which is super intuitive.
Our company has migrated to the PDM and to the new super intuitive interface.

PS: I took the liberty of sending him a letter citing this question ;-)
