automated stair elevation - array issue

[HwLeeGBC]

Hi all, I'm trying to make a stair for elevations that can automatically match unit rise and run by changing number of steps.

the issue is the array for the steps, it modify the block in unpredictable way

Variables:

the block can be modified in height and length

number of steps can be modified in block reference

steps rise and run adjust are self adjusting through changing number of steps

Thanks

ps
the array path curve would be D1

any help would be appreciated or even negative feedback if such kind of array is not possible

I don't think that what you are trying to do is possible using an array.  You might be able to simulate an array using visibility states and a double-lookup and get it to work but it would be very complicated/advanced and I'm not even sure if that is possible.
