Hi Pim,

The Fracture Object is needed to get Single Clones from the Sweep. I produced the Path (for the Sweep) with the Cloner and then used the Sweep. This is a needed step if the Sweep Profile should stay the same diameter but the Path diameter grows.
The Fracture takes it apart to access the ID.

The number of objects, in which way, the ones visible pre-frame or in total over time, and from which file? If you have the Forumla only here in mind, use a Cloner. (Do I get the question at all correctly?)

The Constant Frame, in the file set to ten frames. If they should progress faster use a smaller number.

Let me know if that clears the questions.

The formula
(pow(2;trunc($1/$2)))*$3
It is a Power function, that has one variable as Truncate in it. The $-numbers are the input values.
I'm sure you are aware of this information, but for anyone reading along, and is new to it:

All the best
