Hi,

I am trying to create a parametric open web joist family, I have everything adjustable the way I want it, and have a parametric array dependent on length.  When the array formula functions such that there are extra web members beyond the chords, which are the length of the line I draw in the building project, the joist is built, but when I edit the formula so the web members stay within the chords and therefore the line I draw to make the joist, Revit says "Can't make type 18inchJoist.  Do any of you have ideas for how to fix this(keep web inside of chords and be buildable)?  Sorry if that description is confusing, I will upload the file and you can tinker with it and if you have any suggestions I would really appreciate it!
