Attached is one of the OOTB shear plate families from RS. I want to do something similar to the array of circles in one of our families but I can't quite figure out what the factory did. I added the squares (separate family) to the shear plate family then added an array and assigned my array the same parameter as the factory-made array. But mine isn't functioning the same. When you flex the family, you'll notice that the array of circles spaces itself evenly when the plate is lengthened/shortened where as my array of squares just sort of sits there. When you change the Number of Holes parameter, the number of circles and squares changes so I at least got THAT correct.
