Looking to create a dynamic block for a fixed ladder. Can get the stringers (sides) to stretch, but am having trouble with the rung spacing. Would like to stretch the top rung to a certain elevation while the rungs are equally spaced between 12"-14". Any help will be greatly appreciated.
In the attached dwg you find an example how to solve such issues. You can adapt it to your needs.

Do 3 visibility states. 1 for 12", 1 for 13" and 1 for 14", and use a linear array.
If you have drawn your top section at 2" all you need to do is add the whole top section to the stretch.

You can not get both in the same block, >12" and <14".
You must decide if either
you want to be sure, that the distances are always >12" (then can the distance for short lengths of the ladder be > 14)
OR
you want to be sure, that the distances are always <14" (then can the distance for short lengths of the ladder be <12").
I attached a file with two block variants. If the length of the ladder is too short, can one of the conditions be violated. For greater lengths of the ladder you will fulfill both restrictions, but you will get two different results.
Your choice ...

Example: if the ladder is 17'-10", I would like the rungs equally spaced at 1'-0 9/16".
BTW: Using these values the first step (from bottom to the top line of the first rung) will be 3 9/16". This seems to me very unergonomic and contradicts stair rules.
