Hi Karsten,
attached is my attempt for a grid array with adjustable centres,columns and rows in the 'X' & 'Y'
and the ability to rotate the object. I'm not sure if it's the proper way to do it but it works.
Will you have a look and let me know if it's Ok.
It would be good if the Generative Array info could be accessed as I needed to reset one of the values
of the inputs after removing a connection.

Many Thanks.
Barry.
