Hi Pilou,

> What is exactly the finality of the Object system?

The main goal is to make it easier to work on a more complex project that has many different pieces in it, by allowing certain basic functions like hide/show/isolate/select/deselect work on a predefined batch of objects.

But you still use it in combination with the regular tools, for example it is not meant to replace every single tool such as Move/Copy/Fillet, etc...

You can use it to more easily select objects that are used in those tools though, and really its overall main purpose is to make it easy to manage visibility so you can turn off different sets of objects quickly to make it easier to work one smaller area of a complex model at a time.
