I would like to create a family table of a piece of equipment (filter box) that could via a macro (or others) take as an "input" the number of filters we would like ("number of filters in height" x "number of filters in width"), to then generate the desired assembly with the number of filters wanted using elements that I would have previously designed ( 1 x 2 filter pack; 2 x 2; 3 x 2; 1 x 3; 3 x 3; ...).
It is already possible to do a lot of things with the "Equation Management" tool, if it is a number of occurrences according to a variable or a congestion, no need to make a gas plant. And you can use the assembly custom properties if needed.
