I am creating a set of parametric stairs. All of my constraints are in place for my 2 main work points. I am now trying to make an associative path array to depict the stair treads. Path array works great initially, however when I change my variables for stair height, my stair treads tilt with my work line in such a way that they're no longer parallel to the floor. The angle of the stairs must be variable as it will change from one set of stairs to another. All that said, I am wondering if there is some variable or command that will make the treads retain their ucs orientation regardless of the angle of my path line. I've tried every option while creating the array with no luck. Please Help.
