Associative Pattern For Object

Hello,

My name is Gualda and I have a question about NX10. I have an object and I would like to do and associative pattern following a matrix or a datum. Firstly what I have tried is to do directly a Copy, but it doesn’t have the possibility to be associative which the first object, which should be the master. I show in the next picture P_1.

Also I have tryed creating a featured group and using featured pattern, but it also affected to the original object, chaning the geometry as you can see in picture P_2.

There isnt any comand special for object?

Thanks!!!
