Family Parameter Formula for determining number of arrayed studs

Hello there i am new to creating parametric families

 

I am trying to work out a formulae that can determine the number of studs i can fit in a length that can be varied, with 600mm spacing between the studs. Also with a constraint on the arrayed studs not being allowed to end on top of the independent last stud that is flipped.

I have tried the formula for number of studs being "length/spacing" but this does not give an integer so doesn't work for the actual number of studs that could fit into a length of say 1350mm, as shown in the picture

 

There might be a simple solution that i am missing, but maths is not a strong point of mine :leicht_lächelndes_Gesicht:

Great for the integer problem thank you, but how would i determine the "calculated distance" to be no smaller than 70mm? to keep the last arrayed stud from overlapping

Not a real Revit problem, but more a math issue.

Solution is to test if the distance is less than 70 mm, if so then deduct one from the array Qty

Please mention Revit version, especially when uploading Revit files.

Beside from using a family with formula, you could use curtain walls or railings with a rule to set the mullions or posts/balusters.

Looks like you are building a line-based array. If so, and you pull the line the full extents of the wall, with a fixed spacing, wouldn't Length/Spacing-1 work?

Actually skip the minus 1. I think what you're after is an additional Stud Placement w/ a Visibility Parameter  to turn it off should it overlap the fixed end Stud.    Like this:

If use a curtain wall.
