Hi Pilou,

> About the "same name" for different object : is that the same in Rhino ?

Yes, same thing in Rhino and many other programs. For example, I just tested in PaintShop Pro, Expression, and ViaCAD, and none of these have any problem with assigning the same name to more than 1 object.

It's just a label that you can assign as you wish to help you tag things.
