Stretch 2 Arrays

[SilverlineWoods]

Hi everyone. Using AutoCAD2025. Is there away to stretch two arrays at the same time where the intermittent one stays centered between the primary one? Attached is a sample of the panel I design. The bottom portion has weep holes spaced evenly between the drill holes. Since I have to change the panel size for each application, I would like to keep the drill holes 16" on center max with the weep holes centered in between. Any help will be very much appreciated!

Not sure if I understood 100% but I think this is what you meant?

There are ways to increase the amount of holes as well and have it fully parametric.

New attachment might help clarify. Panels range from 4" to 192" so I have to manually change the quantity of the drill layer (16" on center max) and manually center the weep layer. Wondering if there is a way to link the weep layer array so it stays centered between the drill layer array when I change the drill array quantity after stretching?

Test the attached 1st attempt, if that meets your request.

I think it's possible without using constraints but it's for sure the best way to go here.
Sadly I don't have full autocad anymore

That's perfect! Thank you. Any chance you could give a brief explanation or guide me to something that could show me how this is done? Definitely want to use this in the future.

In the example above (post #4) I used two path arrays. 

In the following video I used two (IMO more performant) rectangular arrays. The main principle in both is the same. 

Correction

Error at 12:11   The Between value for the 2nd array must be "Step" (not Step/2). Sorry

If you have further questions, feel free to ask again.

Really appreciate it! I will have to play around with it after I get some of these panels made.
