A guess form information posted:

have 3 attributes pick up distancey1 to 3, say dy1..dy3, then use choose(smallest(round(copy+1),4),0,dy1,dy2,dy3)
the smallest keeps it within the choose criteria

it maybe best to upload your project

@pcmoor, thank you very much for your help and for your time.

I'm a newbie, and I learned a lot about the "CHOOSE" function from your example. The result is close to what I want, however, I wonder: What happens when I want to increase the number of copies from the DC controller (and also their positions on the Y axis)?

Is this possible with DC or should I learn ruby?

Once again, I thank you very much for helping me.

Hi friends.
I have a DC called "cube", which I want to control by another DC called "data_entered_by_user".
The "cube" must be copied as many times as the user enters in "data_entered_by_user". And the copies must be positioned on the Y axis, according to the distances set by the user in "data_entered_by_user".
I thought the "CONCATENATE" function would do it, but it doesn't work. Is there any way to achieve this?

Hi friends.
I have many walls of different thicknesses, heights and lengths, for which I use them as Groups; but I add some Dynamic Attributes to them.
Question: Is it possible to Redraw them all at once? Maybe with some ruby ​​code?

Hi. I want to show the Volume of the geometry in a DC, to later calculate quantities and costs.
I used this code:

Sketchup.active_model.selection.grep(Sketchup;;ComponentInstance).each do |s|
    if s.volume>-1
      s.set_attribute "dynamic_attributes","vol_inch", s.volume 
      s.set_attribute "dynamic_attributes","volumen_mm", "0"
      s.set_attribute "dynamic_attributes", "_volumen_mm_access","VIEW"
      s.set_attribute "dynamic_attributes","_volumen_mm_formlabel","Volume (cubic ft) " 
      s.set_attribute "dynamic_attributes","_volumen_mm_formula", "ROUND(vol_inch*16387.064,3)"
    end     
    $dc_observers.get_latest_class.redraw_with_undo(s)
 end

Works. But when I modify the geometry the volume does not change.
Is there a way to get the volume in a DC constantly and dynamically as the geometry changes?
