how to resize a copy without affecting the original or resize the original without affecting the size of the copy
Make the copy unique ?
If you just scale a component, without opening it for editing, only that copy will change.
Are you using the DC internal copies?
If so then you need to address each copy by its index.
Like use for lenX
= choose( copy+1, 10,20,45,10,15)
= current("val" & copy+1)
where you have a list of attributes val1 to val10 where 10 is the max number of items
thanks for the answer as always correct
