I would like to create instance from random objects (all inside a same family of course) and I don't know if it is possible or how to do.
I tried System -> create object "my family" and it doesn't work. I hoped that I can use System -> create object "my family(a random number)" but I can't. (EDIT : forget about my family(a random number), it's based on UID or IID : it's not the subject, just a bad idea :D )
Using array is not permited because it allows only number or text.
Any idea ?
