Thanks a lot Michael.

This list is very welcome !!!!
This is a long awaited list!!!!

@You : "...

But you write also :"obj.isCurve - true if it's either a standalone curve or an edge curve."
So...this sentence invalidates the "manual" method I wrote in my previous message ?
LOL :)
Anyway If that's the case, It's better this way !

Grazie (thanks)
