How do I change set/location measurements?

[Raspberry]

Dear Jamesw,

thank you for your tip. For some reason, it doesn't let me select that function. I can percolate the set, but not the "objects". Even if I select everything. Bummer.

I wonder what to do, when your locations changed, and you want to change the parameters of your previz to make it fit?

But thank you for your answer anyway.
