Array with changing size in a Revit family

[virajvoditel]

I want to create an array based family in Revit as shown in the attached image. The sizes vary progressively and can be related with a simple formula, for e.g. side of square 2 = 2 x side of square 1 and so on.

Basically the reason for wanting to use the Array command is because the number of objects is to be kept as a variable. As an alternative what I'm doing is creating the maximum number of objects possible and giving them a visibility parameter according to the number entered by the user. But this may not always be the case that I know the maximum number possible. It needs to be a variable.

TL;DR: A linear array whose parameters change progressively is what I want.

Is this possible in Revit?

And you aren't alone... unfortunately though, currently all items in an array have to be identical.

You could do something like that with Dynamo, where the size of generated geometry is a function of its distance from a point.  The whole thing would not be a family, and the individual items would not be a Revit Array, and to make changes you would have to do so through Dynamo.
